This page is intended to coordinate group orders from distributors such as Adafruit, TAP Plastics, and other such places. We'll use this to maintain lists during the process of coordination, and all lists on the page should be considered provisional and subject to revision and eventually deletion after the order is made. Please date any list you add here, and mention the name, slack handle, and/or email address of the main contact for the order. If you add an item to a list currently being coordinated, please inform the main contact for the order, or else your items may not be purchased.

Order lists should be organized first by requesters and second by the items request, with their quantities and per-item price. So for example, if Wintermute and Neuromancer each want to order a Raspberry Pi Zero, Wintermute wants to also order a Pi Zero case, and Neuromancer wants an HDMI board, the list they would create would look like this:

* Wintermute
# Raspberry Pi Zero ($5, quantity: 1)
# Raspberry Pi Zero case ($2, quantity: 1)
* Neuromancer
# Raspberry Pi Zero ($5, quantity: 1)
# Raspberry Pi Zero HDMI board ($3, quantity: 1)

Items should have enough information associated with them to uniquely identify the items from the distributors web store or physical store.

== Previous Hacker Trips To China ==
::''This will be the 7th Noisebridge Hacker Trip To China.'' 
::''In previous years' Hacker Trip To China, we've visited cities that currently have a hackerspace, visited my manufacturer, Seeed Studio, and other manufacturers. We also visited Tsinghua University, considered the most prestigious university in China, and other schools -- all of which have now starting hackerspaces. China continues to explode with hackerspaces! We also went to the International Exhibition of Inventions Kunshan (IEIK 2014), near Shanghai. And everywhere we went, we were shown around by local geeks, to see what they thought was interesting where they live. Also, wherever we went, those of us interested gave talks, presentations, workshops, and demos. In 2016 we gave presentations at NY University - Shanghai, DFRobot (an open hardware company in Shanghai), Shanghai Maker Carnival, Zhengzhou High School Number 2, "Second Generation and Start-ups" conference in Hangzhou.''

== This year's Hacker Trip To China ==
'''When:''' Tentatively 11-October-2017 (Shanghai?) through tentatively 1-November-2017 (Beijing?).

'''Flight, transportation, and hotel Info''': We were each be on our own to book our own air fare to meet in our starting city (tentatively Shanghai) on 11-October (tentatively), and fly home from out ending city (tentatively Beijing) on 1-November (tentatively). Of course, you can decide to come and go as you please. 

I'll organized the itinerary and the hotels and other transport. I'll pay in advance for some of this, and you can pay me back when we're in China. 

'''Where:''' In each of the cities we will go to, we'll visit some of their local hackerspace(s), and will be shown around by local geeks to see what interested them where they live. We'll also have plenty of time to do "normal" (and spectacular) tourist things too! 

'''Here's some possible places we might visit, leaving plenty of room for the serendipity that makes our Hacker Trip To China truly unique and memorable:''' 
* We may start our trip by meeting in '''Shanghai''' on 11-October-2016. In Shanghai we will visit [http://www.etonnet.com/ my manufacturer (Etonnet)] that I have used for [http://www.tvbgone.com TV-B-Gone] remote controls and [http://www.neurodreamer.com NeuroDreamer] sleep masks, where we will all get to see how products are made, from start to finish, learning how manufacturing works. We will also visit [http://xinchejian.com/ XinCheJian] hackerspace in Shanghai. If there is another [http://www.shanghaimakercarnival.com/ Shanghai Maker Carnival] while we are in town, we will be welcomed there, and we will have a table where we can all show off our projects and give workshops (if you like). We can also visit companies started by hardware hacker geeks, such as [http://www.dfrobot.com/ DFRobot]. We can also visit the [http://www.flickr.com/photos/maltman23/4064240200/in/set-72157622640069902/ Shanghai electronics mall] (a smaller version of the famous electronics mall we will later visit in Shenzhen).
* We may go from Shanghai to '''Hong Kong''' and visit [http://www.dimsumlabs.com/ Dim Sum Labs] hackerspace. We'll also see lots of other cool stuff in Hong Kong. 
* Then we may go across the border to mainland China again, to '''Shenzhen''' to visit [http://www.chaihuo.org/ Chaihuo Makerspace], [http://www.szdiy.org/ SZDIY] hackerspace, [http://litchee.cn/en/ Litchee Lab], and a few other hackerspaces, some of which are real, and hundreds of which are brand new (this year) over-the-top bizarre government-started places where they want to create "the next Apple" (we won't visit them all!). If there is another [http://www.makerfaireshenzhen.com/english Maker Faire Shenzhen] while we are in town, we will be welcomed there, and will be given a booth where we can all show off our projects and give workshops (if you like). We will also visit [http://www.seeedstudio.com Seeed Studio] - the open source hardware company - to meet the cool folks there and to see their manufacturing facilities. We may meet with the founders of [http://dangerousprototypes.com/ Dangerous Prototypes] - another open source hardware company. We'll also visit other manufacturers, to see where all the things we use in our daily lives come from (such as springs, cables, PCBs, packaging, etc., etc.). Of course, we'll also visit the famous (and totally awesome!) [http://www.evilmadscientist.com/article.php/shenzhen/print Huaqiangbei electronics market] in Shenzhen (where, we may again be shown around by a professional buyer from Deal Extreme (dx.com). 
* We may then make our way to '''Beijing''' where we may visit [http://www.bjmakerspace.com/ Beijing Makerspace], and other hackerspaces. We'll also visit Tsinghua University, where they built the world's largest hackerspace last year, and where I've been hacker in residence. Beijing has lots and lots of way amazing stuff to visit and be a part of!

For most of us, our trip will end at the end of three weeks, as many people on our trip will fly home from our last city on (tentatively) 1-November-2016.

''I will probably be in Beijing, as hacker in residence at Tsinghua University for the 6 weeks preceding out Hacker Trip To China 2017. Everyone is welcome to join me in Beijing for any or all of this residency. (And, of course, everyone is free to arrive and leave whenever you like.) 
I will tentatively be flying home from Beijing on 2-November. ''

'''Cost:''' For the Hacker Trip To China 2016, I paid $1,997 total (for 4 weeks), including air fare from SF, food, lodging, transportation, and everything -- including some electronics stuff and some clothing that I bought. 
''As in past years, part of this year's trip may be paid for by Tsinghua University and other places that invite us to give presentations.''

'''#hashtag:''' [https://twitter.com/hashtag/httc2017 #httc2017]      (Hacker Trip To China 2017)

 
 

== Possible itinerary outline for Hacker Trip to China 7 ==

''Everyone is welcome to join me while I am hacker in residence at Tsinghua University from 31-August through 10-October.''
''10-October-2017 -- '''Leave home''' for '''Shanghai''' (arrive in Shanghai on 11-October)''
''11-October-2016 -- We all tentatively meet in '''Shanghai''' -- hotel: Le Tour Traveler's Rest''
'''11-October to 17-October -- Shanghai'''
'''17-October to 19-October -- Hong Kong'''
'''19-October to 24-October -- Shenzhen'''
'''24-October to 28-October -- Beijing''' ''

== You will Need a Chinese Visa!! ==
To go to China, you needed to get a visa!

Everyone should get a multiple-entry Tourist L visa (if you only get a single-entry visa, you won't be able to go to Hong Kong).

* And to get a visa, you need to have a passport that is valid ''at least'' 12 months after you planned to fly away from China (so, e.g., if you are leaving China on 1-November-2017, then your passport needs to be valid through 31-October-2017). Your passport must also have at least ''one entirely blank page''.

* You also need:
** a printout of a filled-out [http://www.china-embassy.org/eng/visas/fd/W020130830801798289342.pdf Visa Application Form V. 2013 of the People's Republic of China] (after we have everything we need I'll email you my filled out form as an example to follow).
** a copy of the information pages of your passport.
** a copy of your most Chinese visa (if you have been to China before).
** one 2"x2" recent color photo (not a printout).
** a screenshot or printout of hotel reservation confirmation (I'll email this to you when I have this).
** a copy of your airline tickets (both to and from China).

* For US citizens, the visa cost $140 (much cheaper for other nationalities). Starting this year, US citizens can get a multiple-entry visa, good for 10 years. We should all apply for a Tourist L visa.

You can pay the fee by Visa, MasterCard, Money Order, Cashier's Check or Company Check. ''Cash or Personal checks are not acceptable.''

To get a visa, you can go to your local Chinese consulate. No appointment is required. You go in one day, and it will be ready for pick up 4 business days later. My experience is that it takes about an hour the first day, and takes only a few minutes to pick up the visa a few days later. (2 to 3 business-day and 1 business day/same-day express service is available for $20 or $30.) 
''NOTE: The Chinese consulates are all closed for holidays on: 27-30 January, 29-30 May, 30-May, 9-June, 4-July, 4-September, 2-October, 9-October and other dates: 
[http://www.chinaconsulatesf.org/eng/lszj/t1424287.htm 2017 Chinese Consulate Holiday Schedule]''
 
(Citizens of US and Europe ''do not'' need a separate visa for Hong Kong.)

The trip is limited to 20 people total (including Mitch) 
-- the first 19 people (after Mitch) who are either there already, or who bought tickets to meet in our Trip's starting city (tentatively Shanghai) on or before 11-October-2016 are the people who are in this Trip        (which probably means flying away from home on or before 10-October) 


Note: Many people have gotten good deals on their plane fares (including me) with the help of my friend Vlad at:        [http://www.flystein.com/ Flystein] Feel free to email me, and I'll send your email to Vlad, who will be happy to help you with your flights.

Official, Semi-Official, one-off and other events at the Noisebridge space.

=Event Calendar=
<onlyinclude>
Not all events make it onto this calendar. Many events only make it to the [https://www.noisebridge.net/pipermail/noisebridge-discuss/ Discussion] or [https://www.noisebridge.net/pipermail/noisebridge-announce/ Announcements] mailing lists, [[IRC]] or in person at [[Meetings | Tuesday meetings]]. Best of all, Noisebridge is about people getting together at the space in San Francisco to do stuff. DO pay attention, as some events just arise organically from the bottom up!

'''Want to host your event at Noisebridge?''' We like seeing classes and talks on interesting things pertaining to various subjects of hacking. Most of all, we like seeing familiar faces. Please participate in the space and our [[Meetings|weekly Tuesday meetings]] to see if we're the right audience for what you want to share before announcing a new event. Additionally, please see our [[Hosting an Event|events hosting page]] for suggestions on how to use Noisebridge for your event/class/workshop.

|description = [[HackTheLeft|Hack the Left]] is an ''anticapitalist'' hackathon, going on for the entire long weekend of February 5th-7th at Noisebridge. This is an experiment to see what happens when you get a bunch of leftists in a room for a weekend with the intention to advance liberatory and ''anticapitalist'' projects using technology. This includes software projects like Tor and Signal, art projects like the Anti-Eviction Mapping Project and Men in Grey, hardware projects like mesh networks and signal jammers, and tools for rad organizations like Anti Police-Crimethink Project and Food Not Bombs. It's clear that there's a huge amount of opportunity for liberatory technology. It's up to us to build it.

== How to get trained to use the laser cutter ==

# Ask a trainer if they will train you
# Schedule a time with the trainer
## The laser training class size is limited to 5 students, so that everyone can see how to operate the laser.
# Get trained
# Get your name on the list of users before the first time you use the machine

The laser training class is pay-what-you-can, and the recommended minimum donation is $20.

== Basic Safety ==
The laser cutter is generally a very safe machine to use. However, as with all industrial machines, you need to treat it with respect. The main safety concerns are creating fires, hurting your eyes or skin, getting crushed by the machine, and creating toxic fumes.

The basics:
* ALWAYS WATCH THE LASER BEAM CUTTING YOUR WORK!
* OPEN THE LID if you see a fire
* BLOW IT OUT if the fire keeps burning
* DON'T CUT UNAPPROVED MATERIALS!

=== Fire ===

[[Image:Laser_water_estop.jpg|thumb|right|upright=3|alt=Laser cutter with water and estop| The water squirt bottle is sitting on top of the laser, and the estop is the round red button.]]

You can really hurt yourself or burn the building down with this machine. If you follow the safety rules, the chances of you causing this is close to zero. Some materials are very flammable on the laser cutter, and shouldn't be cut. Never cut an unapproved material, or a material you can't identify. A laser beam can also initiate a fire if the speed of the cut is too slow or the laser power is set too high.

Ways to not cause fires:
* ALWAYS WATCH THE LASER CUTTER WHENEVER IT IS CUTTING AS FIRES CAN HAPPEN. The laser affects your material by heating it. Your job can change in seconds with the accumulation of heat in your material. Never leave the room while the laser is in operation. If you leave the laser unattended, your access to the laser cutter will be permanently revoked.
* Use reasonable speed/power settings. Start with the recommended speed/power settings for your material. Be patient - resist the temptation to crank the power and speed to rush through your job. This can cause fires.
** There will be some light when material is cut. This light at the point of lasing may be ok as long as it stays with the motion of the laser. If a flame appears while the laser is in operation, stop your job and try again with lower heat settings.
* Know where the fire extinguisher is in case of a fire. The ONLY fire extinguisher that should be used on the laser cutter is the halotron extinguisher right next to the laser cutter. Other fire extinguishers are corrosive and will ruin the machine.

How to put out a fire:
* Push the estop. (To turn the machine back on after the estop was hit, you need to switch the power switch on the right hand side of the machine off and on again).
* Open the lid.
* If it's small, try and blow it out.
* If it's smallish, try and squirt it out with the water squirt bottle sitting on the right hand side of the machine.
* If that doesn't work, use the halotron fire extinguisher to the right of the laser cutter. Aim it at the base of the flame.

=== Damage to eyes and skin ===
The laser beam can instantly and permanently blind you. It can also burn your skin.
* You don't ever want any part of your body in contact with the beam.
* As long as the door is closed, you're safe to look at the laser. There are interlocks on the door that help ensure the laser never operates with the doors open. Don't disable them.

=== Crushing danger ===

The laser cutter is a dumb machine. It doesn't care whether your hand is in the way when it's moving. The head can move when the door is open. Always make sure everyone's hands are out of the machine before moving the head.

Also be very careful not to crash the head into other parts of the machine. Be very careful when moving the z-axis to not crash the head into the bed, and to not move the z-axis if the focus length acrylic circle is under the lens.

=== Fumes ===
The laser cutter burns the things it's cutting, which can create toxic fumes.
* ONLY CUT APPROVED MATERIALS. Cutting nonapproved materials can release really toxic gases, including chlorine and cyanide. These are really bad for humans, as well as being very damaging to the laser cutter.
* The ventilation fan should always be running if the laser cutter is on, even if it's not cutting. It's currently wired such that you can't turn on the laser cutter without the fan turning on, but please make sure it's running.

== Care of the machine ==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

The laser cutter is finely calibrated piece of machinery. Please close the lid gently, and do not push or jar the machine at any time. Do not lean or press on the tray - it's fragile, and needs to be perfectly flat for the laser cutter to cut properly. If you take the honeycomb bed or slats out, please be ULTRA CAREFUL with them - put them somewhere where they won't get damaged or warped.

== Paying for your laser time ==

The laser cutter has parts that wear out over time, which can be quite costly to replace, especially the laser tube. A new tube costs several thousand dollars. Thus, we require people to pay for the time on the laser they use, so we can pay for new parts. The cost for using the laser cutter is $5 per hour of cutting time.

To figure out how much time your job takes, press the File button, select your file, and then select Work Time from the menu. It will tell you in hours:minutes.seconds.

There is a laser cutter donation box on the wall of the Sparkle Forge room. Please pay for the cutting time you actually use, even if you end up running your job multiple times.

== Workflows ==

=== Overall Workflow ===

This is the overall structure of the workflow. Each part is elaborated below.

# Laser start up
# Material setup
# Convert file to DXF
# Load file onto the machine
# Dry run
# Cut/Engrave
# Laser shut down
# Cleanup

=== Laser start up ===

[[Image:Laser_chiller.jpg|thumb|right|upright=3|alt=Laser chiller| The laser chiller is the box on the bottom left of this photograph. If the laser doesn't beep when it turns on, you should turn on the chiller manually.]]

# Turn on power and ensure that the fan and chiller are running. If you do not hear beeps when the laser starts up, the chiller is not running and you must turn it on.
# Move the head as far forward and right as possible, close to the controls

=== Material setup ===

# Clean the bed of any scraps that may be on it
# Move the cut head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Raise the bed to the desired height, watching the laser head to avoid crashes
# Move the laser head as far back and right as possible
# Place material on the bed
# Focus the laser (do at least for each distinct thickness, optimally do for each piece of material)

=== Focusing the laser ===

[[Image:Laser_shelf.jpg|thumb|right|upright=3|alt=Shelf by laser cutter | This is the shelf to the left of the laser cutter. The acrylic disks used for focusing the laser are in the toolbox with the yellow lid.]]

Noisebridge has acryllic disks cut to various thicknesses that can be used to accurately focus the laser. Specifically the laser head needs to be locked to 8mm above the surface of the material you're cutting.

# Place the material on the cut bed
# Move the cut head to the center of the area to cut, watching the laser head to avoid crashes w/ material
# Loosen the wing nut and raise the head all the way up
# Place the focusing discs on the material under the head
# Lower the head until it just touches the focusing disc (8mm above material)
# Lock the head in place (tighten the wing nut)
# Remove the focusing discs

=== Convert an image in Inkscape to a DXF file ===

# Load the image into Inkscape
# Set the different cut paths to different colors (for controlling settings, etc.)
# Perform any debugging steps (by default you should perform all of them b/c of errors in the laser software)
# Save as a DXF. Be sure to make the units be millimeters so that importing later will correctly scale the image.

=== Debugging DXF Problems ===

Sometimes exporting to DXF introduces bizarre extra lines. There are two things to try to debug. The first is to convert objects to paths:

# Select all the problematic shapes
# Path > Object to Path

If this fails to resolve the issue, you can try a more radical solution which will eliminate all bezier paths entirely:

# Select all the problematic shapes
# Convert bezier paths to lines (Extensions > Modify Path > Flatten Bezier).

Flatness 0.5 is good to start with. Smaller = better approximation of the curves. A lower flatness number takes more time to compute, but also produces a better approximation to the curve.

Sometimes need to select the path's directly with the path tool (but not the points!).

Also see http://www.pstoedit.net/ for conversion from svg to dxf files.

=== Loading into the laser cutter software ===

# Import the file with File > Import
# Resize as needed, tho if the file was exported w/ millimeter units, the software should also import the image with the correct size.
# Set the cut order:
##* EITHER Set the cut order to inside-out (Handle > Cut optimize > Inside to outside)
##* OR Manually specify cut order with the Set cut property tool (Edit > Set cutting property). See below for more details.
# Set the speed and power for the layers as necessary, and the process mode for each layer to either cut (for continuous line cutting) or dot (for dashed line cutting) or scan (for engraving)
# Optionally, simulate the cutting/engraving process.
# Download to the machine (Laser Work panel on the bottom right).

=== Manually specifying cut order ===

In the Set cutting property window (Edit > Set cutting property), you can manually re-order the cut paths. In the window, you'll see an image of the workpiece, and to its right, two lists of paths. When you first open the window, all of the cut paths are in the left. If you select a path (either in the image or in the list) and click the button labeled ">>", this path will be transferred to the end of the right list of paths. If you click ">>>", all of the paths in the left list will be moved to the end of the right list (preserving order). Similarly, clicking "<<<" will move the right list to the end of the left list. If you select a cut path in the right list, the up and down arrow buttons will reorder that path in the chosen direction.

=== Loading speed and power settings from library ===

# In the top right panel, double click the layer of interest
# Click "Load parameters from library"
# Select the library item
# Click "Load"

=== Saving power and speed settings to library ===

# In the top right panel, double click the layer of interest
# Make sure the layer is set to the desired parameters
# Click "Load parameters from library"
# Click "Save as"
# Enter a name and optionally some notes
# Click "Ok"

=== Simulation ===

# Open the simulation window with either Edit > Preview or the toolbar button labelled with a monitor.
# Click the Simulation button in the right panel

=== Cutting ===

# Select the file to use using the File button
# Move the head to the initial guess origin with the arrow buttons
# Test the frame with the Frame button adjust origin as necessary
# Set the origin by pressing Origin
# Test the cut by turning the laser power off and pressing the Start/Pause button
# Turn the laser power on
# Cut by pressing the Start/Pause button

=== Engraving ===

TODO

=== Cancel a cut/dry run ===

# Pause with the Start/Pause button
# Cancel and move back to the origin with the Esc button

=== Laser shut down ===

# Move the head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Let the fan run for a little bit (~30 seconds)
# Turn the power off

=== Cleanup ===

[[Image:Laser_tray.jpg|thumb|right|upright=3|alt=Laser bottom tray| This is the bottom tray of the laser, which should be cleaned out after use.]]

# Remove pieces of material scrap left on the bed
# Open the tray door on the front bottom and empty the scraps left there

=== Calculating work time ===

On the computer:

* Open the simulation window (see above). Total work time and time of laser use are displayed in the top right. Donations should be calculated by laser use, not total work time.

On the machine:

* Whole file: File > Select file > Right Arrow > Work Time > Enter
* Current run: Pause the cut, then check time at the bottom right

== Fusion 360 ==
Fusion 360 is a free CAD (Computer Aided Design) program from Autodesk for designing 3D parts, and arguably the best one currently available. If you're designing something complex on the laser cutter, particularly with multiple parts that need to fit together, I highly recommend it over drawing programs like Inkscape. It also has CAM (Computer Aided Manufacturing) capabilities, which makes it very useful for CNC machining and laser cutting. There's a copy of the software on the laser cutter computer, and you can download it [http://www.autodesk.com/products/fusion-360/overview here]. It's free as long as you make less than $100k per year using it.

=== Workflow 1: The Quick and Dirty Way ===
This is the fastest way, and works a lot of the time
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Make sure your part is designed using a single sketch, and that you want to cut all the lines in that sketch. If not, go to [[#Workflow 2: The Middle Ground]]
# Right click on your sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 2: The Middle Ground ===
If you're not sure, this is probably where you should start.
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Right click on the top surface of the part you want to cut, and click Create Sketch
# Hit the P key to open the Project dialog box, then select the top surface of your part, and any other lines you want to cut
# Hit OK, then remove any lines you don't want cut
# Open the Sketches folder near the top of the tree, then right click your new sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 3: The Long Way ===
This allows more complicated things like exporting splines, which doesn't work with the above methods, kerf compensation, which makes your parts fit together snugly, but you can also use the above methods and then do it in RDWorks, or lead-ins and lead-outs, which can make for a cleaner cut, but I can't figure out how to get RDWorks to import correctly.
# Design a part to be laser cut by drawing a 2D sketch and extruding it
# Go to the CAM workspace by clicking the Model button in the top left, then selecting CAM
# Select the Waterjet operation (if you don't see this, turn it on under Preferences -> Preview)
## Set Type to Laser Cutting
## Select the Cutting Mode, either Through - Auto or Etch
## Look up the kerf of the material you're cutting in the [[#Known good materials]] section, and enter that in Kerf Width, or if your material's not listed, cut one a [http://www.thingiverse.com/thing:1166680 kerf gauge] and put the result in the wiki. The kerf changes depending on the thickness, speed and power. Setting a larger kerf width will make your parts fit tighter, and setting a smaller kerf will make them looser.
## Select the contours of your part that you want to cut
## Go to the Passes tab, and change Compensation Type to In Computer
## Hit OK to close the dialog box, and you can see a preview of your tool path. You can go back to edit it by double clicking the contour operation in the tree on the left
# To export to DXF, click the Post Process button, which says G1 G2. Make sure rdworkslaser is selected as your post processor, type a name for the export and hit Post. Then select the folder to put it in.
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]
# Fusion automatically orders the cuts from inside out and in the fastest order, but RDWorks doesn't always respect that order, so you may need to optimize the cut order again

=== Advanced Options ===
# If you're using your own computer for the first time and not the laser cutter desktop, you have to enable the laser cutter support which is still in beta, by clicking on your name in the top right, then Preferences, Preview, and checking "CAM - Waterjet/Laser/Plasma cutter support". You will also need to download the custom post processor that we use for this laser.
# There's a simulate button to the left of the Post Process button, if you want to do it in Fusion
# If you want to disable or tweak the lead ins and lead outs, you can go to the Linking tab. Lead ins and lead outs can fix the bump you get on the side of your part where the laser started and stopped, but they also make extra cuts in your scrap material, which you may want to keep. In this tab you can also specify the Entry Position for each cut path.
# You can disable Kerf Compensation by settting Sideways Compensation to Center under the Passes tab, though this is not recommended

== Techniques ==

=== Text Cutting ===

In Inkscape, after converting the text object to a path, it's necessary to ungroup the text as well, to create separate paths, prior to flattening the bezier curves.

Engraved text requires no other special technique because no cuts are made, but text cutting is non-trivial. Because of loops, it's sometimes desirable to use a stencil font, especially at smaller scales where legibility is important. 1001 Fonts has a number of stencil fonts for free. At 10pt, some good fonts are Marsh, Spacedock, and Allerta.

=== Negative Space Engraving ===

You can engrave a vector shape with a hole in the middle of it, so that you get enclosed portions that are not engraved in the middle of fully engraved portions. To do this, when you construct the image in your editor of choice, simply perform subtraction between the relevant paths, to remove the inner part. In the RDWorks laser software, the two paths will show up, and be independently editable (making them look like just two distinct paths to engrave), but they will engrave correctly as a negative space. Obviously test this w/ your software; this technique is known to work using Inkscape.

=== Kerf Compensation ===

For any given layer, you can compensate for the kerf (width of the cut) by opening it's settings and clicking the "Advance" button next to the "Seal" input box towards the middle-bottom. Enable sew compensation, and pick the direction and sew width (kerf size). The inward direction will make the actual cut move toward the inside of a closed cut path, outward will move it towards the outside.

In general, for cuts on the outside, you want to move outward, to move the actual cut edge be exactly where the path is in your design. For cuts on the inside, you want to use the inward direction.

== Troubleshooting ==

=== File doesn't appear in laser cutter after successful download ===
If the laser cutter has 99 files loaded into it, new files will not show up. To fix this, open up RDWorks8, and on the right side, select the Doc tab. Inside that tab, click Read to read all the files in the laser cutter, and then click Delete all.
[[Image:laser_cutter_read_files.png|thumb|right|upright=3|alt=read files | This is the button used to read stored files from the laser cutter.]] [[Image:laser_cutter_delete_all_files.png|thumb|right|upright=3|alt=delete all files | This is the button used to delete all stored files from the laser cutter to make room for new ones.]]

== Maintenance==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

== Chlorine material test ==

Before you cut any new material you *must* check that it is safe to cut; specifically that it will not produce chlorine gas when it is burned by the cutting laser. Chlorine is extremely dangerous in its gaseous form and so must be avoided at all costs.

To test a new material, you'll need a sample of the material, a small copper rod (about the thickness of a coat hanger), a pliars, and a handheld propane torch. We'll test for the presence of chlorine by burning a sample of the material in a high temperature propane flame and observe the visible emission spectra. Chrlorine produces a bright green light when burned, and so will be very obvious when you're testing your material.

First, turn on the ventilation on the Sparkle Forge. The switch for this is under the sign that says "For Non-Laser Fires Only", and above the non-laser fire extinguisher. Then, light the propane torch and set it to rest upright on a stable surface. Taking the pliar, hold the piece of copper in the blue part of the flame to heat it. As the copper begins to heat sufficiently it'll cause the flame to turn an orange color. A consistent orange color means that the copper has no residue material on its surface and so is clean enough to use as a test. If you observe non-orange flames when you burn the copper you may need to clean in further, either by waiting for the excess material to burn off, or by scrubbing the surface of the copper when it has cooled.

Once the copper is burning, take the hot copper and melt a sample of the new material onto it. For example if you were testing a new form of plastic you can roll the hot copper rod on the material, melting some of it onto the copper rod's surface.

With this done, place the copper rod back into the blue part of the flame. Observe the colors of the emission spectra from the new material burning. If you observe a bright green color, then the material contains chlorine and thus *must not* be burned further. Ventilate your surrounding area to avoid breathing it in. If you observe no green color as you burn your material sample, then the material is likely safe to use with the laser cutter.

Here is a video example by Zach in NYCResistor with a known good and known bad material: https://www.youtube.com/watch?v=D0_4NLmeSTI

== BANNED MATERIALS (NEVER USE THESE) ==

These materials '''must not be used in the laser cutter'''.

|-
| PVC || Contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Vinyl || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| PVC Foams || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Foam Core || Usually made with PVC which is harmful as listed above.
|-
| Styrofoam || Can cause flash fires

| ABS || Gives of hydrogen cyanide
|-
| Fiberglass ||
|-
| Metals || Cannot be etched by this type of laser. Also is harmful as the reflective surface may cause the laser to be reflected back up to the head, damaging it. If someone claims to be etching metal using this type of laser then they are etching a metal with a plastic coating, anodized surface, or some other etchable surface on top.

== Known good materials ==

These materials are known to be ok for use with the laser cutter. The speed and power of the laser cutter will need to be set appropriately for the material and thickness in use. Below is a table showing the suggested settings when cutting or etching them.

== How to get trained to use the laser cutter ==

# Ask a trainer if they will train you
# Schedule a time with the trainer
## The laser training class size is limited to 5 students, so that everyone can see how to operate the laser.
# Get trained
# Get your name on the list of users before the first time you use the machine

The laser training class is pay-what-you-can, and the recommended minimum donation is $20.

== Basic Safety ==
The laser cutter is generally a very safe machine to use. However, as with all industrial machines, you need to treat it with respect. The main safety concerns are creating fires, hurting your eyes or skin, getting crushed by the machine, and creating toxic fumes.

The basics:
* ALWAYS WATCH THE LASER BEAM CUTTING YOUR WORK!
* OPEN THE LID if you see a fire
* BLOW IT OUT if the fire keeps burning
* DON'T CUT UNAPPROVED MATERIALS!

=== Fire ===

[[Image:Laser_water_estop.jpg|thumb|right|upright=3|alt=Laser cutter with water and estop| The water squirt bottle is sitting on top of the laser, and the estop is the round red button.]]

You can really hurt yourself or burn the building down with this machine. If you follow the safety rules, the chances of you causing this is close to zero. Some materials are very flammable on the laser cutter, and shouldn't be cut. Never cut an unapproved material, or a material you can't identify. A laser beam can also initiate a fire if the speed of the cut is too slow or the laser power is set too high.

Ways to not cause fires:
* ALWAYS WATCH THE LASER CUTTER WHENEVER IT IS CUTTING AS FIRES CAN HAPPEN. The laser affects your material by heating it. Your job can change in seconds with the accumulation of heat in your material. Never leave the room while the laser is in operation. If you leave the laser unattended, your access to the laser cutter will be permanently revoked.
* Use reasonable speed/power settings. Start with the recommended speed/power settings for your material. Be patient - resist the temptation to crank the power and speed to rush through your job. This can cause fires.
** There will be some light when material is cut. This light at the point of lasing may be ok as long as it stays with the motion of the laser. If a flame appears while the laser is in operation, stop your job and try again with lower heat settings.
* Know where the fire extinguisher is in case of a fire. The ONLY fire extinguisher that should be used on the laser cutter is the halotron extinguisher right next to the laser cutter. Other fire extinguishers are corrosive and will ruin the machine.

How to put out a fire:
* Push the estop. (To turn the machine back on after the estop was hit, you need to switch the power switch on the right hand side of the machine off and on again).
* Open the lid.
* If it's small, try and blow it out.
* If it's smallish, try and squirt it out with the water squirt bottle sitting on the right hand side of the machine.
* If that doesn't work, use the halotron fire extinguisher to the right of the laser cutter. Aim it at the base of the flame.

=== Damage to eyes and skin ===
The laser beam can instantly and permanently blind you. It can also burn your skin.
* You don't ever want any part of your body in contact with the beam.
* As long as the door is closed, you're safe to look at the laser. There are interlocks on the door that help ensure the laser never operates with the doors open. Don't disable them.

=== Crushing danger ===

The laser cutter is a dumb machine. It doesn't care whether your hand is in the way when it's moving. The head can move when the door is open. Always make sure everyone's hands are out of the machine before moving the head.

Also be very careful not to crash the head into other parts of the machine. Be very careful when moving the z-axis to not crash the head into the bed, and to not move the z-axis if the focus length acrylic circle is under the lens.

=== Fumes ===
The laser cutter burns the things it's cutting, which can create toxic fumes.
* ONLY CUT APPROVED MATERIALS. Cutting nonapproved materials can release really toxic gases, including chlorine and cyanide. These are really bad for humans, as well as being very damaging to the laser cutter.
* The ventilation fan should always be running if the laser cutter is on, even if it's not cutting. It's currently wired such that you can't turn on the laser cutter without the fan turning on, but please make sure it's running.

== Care of the machine ==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

The laser cutter is finely calibrated piece of machinery. Please close the lid gently, and do not push or jar the machine at any time. Do not lean or press on the tray - it's fragile, and needs to be perfectly flat for the laser cutter to cut properly. If you take the honeycomb bed or slats out, please be ULTRA CAREFUL with them - put them somewhere where they won't get damaged or warped.

== Paying for your laser time ==

The laser cutter has parts that wear out over time, which can be quite costly to replace, especially the laser tube. A new tube costs several thousand dollars. Thus, we require people to pay for the time on the laser they use, so we can pay for new parts. The cost for using the laser cutter is $5 per hour of cutting time.

To figure out how much time your job takes, press the File button, select your file, and then select Work Time from the menu. It will tell you in hours:minutes.seconds.

There is a laser cutter donation box on the wall of the Sparkle Forge room. Please pay for the cutting time you actually use, even if you end up running your job multiple times.

== Workflows ==

=== Overall Workflow ===

This is the overall structure of the workflow. Each part is elaborated below.

# Laser start up
# Material setup
# Convert file to DXF
# Load file onto the machine
# Dry run
# Cut/Engrave
# Laser shut down
# Cleanup

=== Laser start up ===

[[Image:Laser_chiller.jpg|thumb|right|upright=3|alt=Laser chiller| The laser chiller is the box on the bottom left of this photograph. If the laser doesn't beep when it turns on, you should turn on the chiller manually.]]

# Turn on power and ensure that the fan and chiller are running. If you do not hear beeps when the laser starts up, the chiller is not running and you must turn it on.
# Move the head as far forward and right as possible, close to the controls

=== Material setup ===

# Clean the bed of any scraps that may be on it
# Move the cut head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Raise the bed to the desired height, watching the laser head to avoid crashes
# Move the laser head as far back and right as possible
# Place material on the bed
# Focus the laser (do at least for each distinct thickness, optimally do for each piece of material)

=== Focusing the laser ===

[[Image:Laser_shelf.jpg|thumb|right|upright=3|alt=Shelf by laser cutter | This is the shelf to the left of the laser cutter. The acrylic disks used for focusing the laser are in the toolbox with the yellow lid.]]

Noisebridge has acryllic disks cut to various thicknesses that can be used to accurately focus the laser. Specifically the laser head needs to be locked to 8mm above the surface of the material you're cutting.

# Place the material on the cut bed
# Move the cut head to the center of the area to cut, watching the laser head to avoid crashes w/ material
# Loosen the wing nut and raise the head all the way up
# Place the focusing discs on the material under the head
# Lower the head until it just touches the focusing disc (8mm above material)
# Lock the head in place (tighten the wing nut)
# Remove the focusing discs

=== Convert an image in Inkscape to a DXF file ===

# Load the image into Inkscape
# Set the different cut paths to different colors (for controlling settings, etc.)
# Perform any debugging steps (by default you should perform all of them b/c of errors in the laser software)
# Save as a DXF. Be sure to make the units be millimeters so that importing later will correctly scale the image.

=== Debugging DXF Problems ===

Sometimes exporting to DXF introduces bizarre extra lines. There are two things to try to debug. The first is to convert objects to paths:

# Select all the problematic shapes
# Path > Object to Path

If this fails to resolve the issue, you can try a more radical solution which will eliminate all bezier paths entirely:

# Select all the problematic shapes
# Convert bezier paths to lines (Extensions > Modify Path > Flatten Bezier).

Flatness 0.5 is good to start with. Smaller = better approximation of the curves. A lower flatness number takes more time to compute, but also produces a better approximation to the curve.

Sometimes need to select the path's directly with the path tool (but not the points!).

Also see http://www.pstoedit.net/ for conversion from svg to dxf files.

=== Loading into the laser cutter software ===

# Import the file with File > Import
# Resize as needed, tho if the file was exported w/ millimeter units, the software should also import the image with the correct size.
# Set the cut order:
##* EITHER Set the cut order to inside-out (Handle > Cut optimize > Inside to outside)
##* OR Manually specify cut order with the Set cut property tool (Edit > Set cutting property). See below for more details.
# Set the speed and power for the layers as necessary, and the process mode for each layer to either cut (for continuous line cutting) or dot (for dashed line cutting) or scan (for engraving)
# Optionally, simulate the cutting/engraving process.
# Download to the machine (Laser Work panel on the bottom right).

=== Manually specifying cut order ===

In the Set cutting property window (Edit > Set cutting property), you can manually re-order the cut paths. In the window, you'll see an image of the workpiece, and to its right, two lists of paths. When you first open the window, all of the cut paths are in the left. If you select a path (either in the image or in the list) and click the button labeled ">>", this path will be transferred to the end of the right list of paths. If you click ">>>", all of the paths in the left list will be moved to the end of the right list (preserving order). Similarly, clicking "<<<" will move the right list to the end of the left list. If you select a cut path in the right list, the up and down arrow buttons will reorder that path in the chosen direction.

=== Loading speed and power settings from library ===

# In the top right panel, double click the layer of interest
# Click "Load parameters from library"
# Select the library item
# Click "Load"

=== Saving power and speed settings to library ===

# In the top right panel, double click the layer of interest
# Make sure the layer is set to the desired parameters
# Click "Load parameters from library"
# Click "Save as"
# Enter a name and optionally some notes
# Click "Ok"

=== Simulation ===

# Open the simulation window with either Edit > Preview or the toolbar button labelled with a monitor.
# Click the Simulation button in the right panel

=== Cutting ===

# Select the file to use using the File button
# Move the head to the initial guess origin with the arrow buttons
# Test the frame with the Frame button adjust origin as necessary
# Set the origin by pressing Origin
# Test the cut by turning the laser power off and pressing the Start/Pause button
# Turn the laser power on
# Cut by pressing the Start/Pause button

=== Engraving ===

TODO

=== Cancel a cut/dry run ===

# Pause with the Start/Pause button
# Cancel and move back to the origin with the Esc button

=== Laser shut down ===

# Move the head as far forward and right as possible (near the controls)
# Raise the laser head as far up as possible
# Let the fan run for a little bit (~30 seconds)
# Turn the power off

=== Cleanup ===

[[Image:Laser_tray.jpg|thumb|right|upright=3|alt=Laser bottom tray| This is the bottom tray of the laser, which should be cleaned out after use.]]

# Remove pieces of material scrap left on the bed
# Open the tray door on the front bottom and empty the scraps left there

=== Calculating work time ===

On the computer:

* Open the simulation window (see above). Total work time and time of laser use are displayed in the top right. Donations should be calculated by laser use, not total work time.

On the machine:

* Whole file: File > Select file > Right Arrow > Work Time > Enter
* Current run: Pause the cut, then check time at the bottom right

== Fusion 360 ==
Fusion 360 is a free CAD (Computer Aided Design) program from Autodesk for designing 3D parts, and arguably the best one currently available. If you're designing something complex on the laser cutter, particularly with multiple parts that need to fit together, I highly recommend it over drawing programs like Inkscape. It also has CAM (Computer Aided Manufacturing) capabilities, which makes it very useful for CNC machining and laser cutting. There's a copy of the software on the laser cutter computer, and you can download it [http://www.autodesk.com/products/fusion-360/overview here]. It's free as long as you make less than $100k per year using it.

=== Workflow 1: The Quick and Dirty Way ===
This is the fastest way, and works a lot of the time
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Make sure your part is designed using a single sketch, and that you want to cut all the lines in that sketch. If not, go to [[#Workflow 2: The Middle Ground]]
# Right click on your sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 2: The Middle Ground ===
If you're not sure, this is probably where you should start.
# Make sure your sketch only contains straight lines, arcs, and circles, and no spline curves. If your sketch has splines, go to [[#Workflow 3: The Long Way]]
# Right click on the top surface of the part you want to cut, and click Create Sketch
# Hit the P key to open the Project dialog box, then select the top surface of your part, and any other lines you want to cut
# Hit OK, then remove any lines you don't want cut
# Open the Sketches folder near the top of the tree, then right click your new sketch and click Save As DXF
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]

=== Workflow 3: The Long Way ===
This allows more complicated things like exporting splines, which doesn't work with the above methods, kerf compensation, which makes your parts fit together snugly, but you can also use the above methods and then do it in RDWorks, or lead-ins and lead-outs, which can make for a cleaner cut, but I can't figure out how to get RDWorks to import correctly.
# Design a part to be laser cut by drawing a 2D sketch and extruding it
# Go to the CAM workspace by clicking the Model button in the top left, then selecting CAM
# Select the Waterjet operation (if you don't see this, turn it on under Preferences -> Preview)
## Set Type to Laser Cutting
## Select the Cutting Mode, either Through - Auto or Etch
## Look up the kerf of the material you're cutting in the [[#Known good materials]] section, and enter that in Kerf Width, or if your material's not listed, cut one a [http://www.thingiverse.com/thing:1166680 kerf gauge] and put the result in the wiki. The kerf changes depending on the thickness, speed and power. Setting a larger kerf width will make your parts fit tighter, and setting a smaller kerf will make them looser.
## Select the contours of your part that you want to cut
## Go to the Passes tab, and change Compensation Type to In Computer
## Hit OK to close the dialog box, and you can see a preview of your tool path. You can go back to edit it by double clicking the contour operation in the tree on the left
# To export to DXF, click the Post Process button, which says G1 G2. Make sure rdworkslaser is selected as your post processor, type a name for the export and hit Post. Then select the folder to put it in.
# Import the DXF in RDWorks, and continue with the standard workflow starting at [[#Loading into the laser cutter software]]
# Fusion automatically orders the cuts from inside out and in the fastest order, but RDWorks doesn't always respect that order, so you may need to optimize the cut order again

=== Advanced Options ===
# If you're using your own computer for the first time and not the laser cutter desktop, you have to enable the laser cutter support which is still in beta, by clicking on your name in the top right, then Preferences, Preview, and checking "CAM - Waterjet/Laser/Plasma cutter support". You will also need to download the custom post processor that we use for this laser.
# There's a simulate button to the left of the Post Process button, if you want to do it in Fusion
# If you want to disable or tweak the lead ins and lead outs, you can go to the Linking tab. Lead ins and lead outs can fix the bump you get on the side of your part where the laser started and stopped, but they also make extra cuts in your scrap material, which you may want to keep. In this tab you can also specify the Entry Position for each cut path.
# You can disable Kerf Compensation by settting Sideways Compensation to Center under the Passes tab, though this is not recommended

== Techniques ==

=== Text Cutting ===

In Inkscape, after converting the text object to a path, it's necessary to ungroup the text as well, to create separate paths, prior to flattening the bezier curves.

Engraved text requires no other special technique because no cuts are made, but text cutting is non-trivial. Because of loops, it's sometimes desirable to use a stencil font, especially at smaller scales where legibility is important. 1001 Fonts has a number of stencil fonts for free. At 10pt, some good fonts are Marsh, Spacedock, and Allerta.

=== Negative Space Engraving ===

You can engrave a vector shape with a hole in the middle of it, so that you get enclosed portions that are not engraved in the middle of fully engraved portions. To do this, when you construct the image in your editor of choice, simply perform subtraction between the relevant paths, to remove the inner part. In the RDWorks laser software, the two paths will show up, and be independently editable (making them look like just two distinct paths to engrave), but they will engrave correctly as a negative space. Obviously test this w/ your software; this technique is known to work using Inkscape.

=== Kerf Compensation ===

For any given layer, you can compensate for the kerf (width of the cut) by opening it's settings and clicking the "Advance" button next to the "Seal" input box towards the middle-bottom. Enable sew compensation, and pick the direction and sew width (kerf size). The inward direction will make the actual cut move toward the inside of a closed cut path, outward will move it towards the outside.

In general, for cuts on the outside, you want to move outward, to move the actual cut edge be exactly where the path is in your design. For cuts on the inside, you want to use the inward direction.

== Troubleshooting ==

=== File doesn't appear in laser cutter after successful download ===
If the laser cutter has 99 files loaded into it, new files will not show up. To fix this, open up RDWorks8, and on the right side, select the Doc tab. Inside that tab, click Read to read all the files in the laser cutter, and then click Delete all.
[[Image:laser_cutter_read_files.png|thumb|right|upright=3|alt=read files | This is the button used to read stored files from the laser cutter.]] [[Image:laser_cutter_delete_all_files.png|thumb|right|upright=3|alt=delete all files | This is the button used to delete all stored files from the laser cutter to make room for new ones.]]

== Maintenance==

'''Please don't perform any maintenance on the machine (including cleaning lenses/mirrors or aligning mirrors) unless you've specifically trained on it.'''

* TEMP note: some check(s) may be included outside of maintenance so a user can trigger a maintenance notification
* DON'T - let someone who has been trained do it
* how to tell if the lens is dirty (or getting old?)
* how to tell if the mirrors are dirty
** Cleaning the mirrors
*** ethanol solution? isopropanol? - see manual.
*** fabric must be non scratch - see manual.
* Checking and performing mirror alignment
** Safety - remove gratings and any other reflective surfaces before any maintenance that requires disabling the door sensors.
** TEMP note: in restrospect the alignment was a very dangerous situation. mirror paths were not checked before powering on the laser with the door open with many people around. (or maybe nigel is just insanely good at configuring mirrors... still... reddit.com/r/OSHA)
** Tape test - mirrors 1,2,3 and their corresponding exits. Slightly propped laser tube.
** vertical/horizontal alignment by brass dial.
* Checking chiller tank water volume
** Chiller alarm - what does it mean
** Checking tank water volume
** Refilling tank water
* Cleaning the bed and waste drawer (this section probably should be moved to usage)

== Chlorine material test ==

Before you cut any new material you *must* check that it is safe to cut; specifically that it will not produce chlorine gas when it is burned by the cutting laser. Chlorine is extremely dangerous in its gaseous form and so must be avoided at all costs.

To test a new material, you'll need a sample of the material, a small copper rod (about the thickness of a coat hanger), a pliars, and a handheld propane torch. We'll test for the presence of chlorine by burning a sample of the material in a high temperature propane flame and observe the visible emission spectra. Chrlorine produces a bright green light when burned, and so will be very obvious when you're testing your material.

First, turn on the ventilation on the Sparkle Forge. The switch for this is under the sign that says "For Non-Laser Fires Only", and above the non-laser fire extinguisher. Then, light the propane torch and set it to rest upright on a stable surface. Taking the pliar, hold the piece of copper in the blue part of the flame to heat it. As the copper begins to heat sufficiently it'll cause the flame to turn an orange color. A consistent orange color means that the copper has no residue material on its surface and so is clean enough to use as a test. If you observe non-orange flames when you burn the copper you may need to clean in further, either by waiting for the excess material to burn off, or by scrubbing the surface of the copper when it has cooled.

Once the copper is burning, take the hot copper and melt a sample of the new material onto it. For example if you were testing a new form of plastic you can roll the hot copper rod on the material, melting some of it onto the copper rod's surface.

With this done, place the copper rod back into the blue part of the flame. Observe the colors of the emission spectra from the new material burning. If you observe a bright green color, then the material contains chlorine and thus *must not* be burned further. Ventilate your surrounding area to avoid breathing it in. If you observe no green color as you burn your material sample, then the material is likely safe to use with the laser cutter.

Here is a video example by Zach in NYCResistor with a known good and known bad material: https://www.youtube.com/watch?v=D0_4NLmeSTI

== BANNED MATERIALS (NEVER USE THESE) ==

These materials '''must not be used in the laser cutter'''.

{|border="1" cellpadding="5" cellspacing="0"
|-
! colspan="10" bgcolor="#ccc" | Bad materials
|-
! Material
! Notes
|-
| PVC || Contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Vinyl || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| PVC Foams || Most contains chlorine. Will produce hydrogen chloride gas when used which is extremely toxic and also damages the laser optics.
|-
| Foam Core || Usually made with PVC which is harmful as listed above.
|-
| Styrofoam || Can cause flash fires
|-
| Polycarbonate or PETG || Does not cut. TAP plastics sells both this and acrylic. '''Be sure to read your labels when purchasing material'''. Lexan is the trade name for Polycarbonate, while Plexiglass is the trade name for acrylic.
|-
| ABS || Gives of hydrogen cyanide
|-
| Fiberglass ||
|-
| Metals || Cannot be etched by this type of laser. Also is harmful as the reflective surface may cause the laser to be reflected back up to the head, damaging it. If someone claims to be etching metal using this type of laser then they are etching a metal with a plastic coating, anodized surface, or some other etchable surface on top.

== Known good materials ==

These materials are known to be ok for use with the laser cutter. The speed and power of the laser cutter will need to be set appropriately for the material and thickness in use. Below is a table showing the suggested settings when cutting or etching them.

'''Some friends of Noisebridge from China have donate a really nice brand new, fully supported, laser cutter to Noisebridge!'''

In February of 2016 we were approached by [http://www.kaitianlaser.com/ Beijing Kaitian Tech. Co., Ltd], after Mitch gave them a tour of Noisebridge they offered us a new 100w laser cutter as a donation (with the stipulation of us taking care of shipping costs). As of July 1st 2016 (and after a crazy adventure involving a rental truck, a forklift, and a lot of Indian pizza), we now have the laser in house. Please check out our action items to see what needs to happen next.

=Current Action Items=
* Start the process of documentation through the [[Laser Manual]]
** Safety
** Training
** Materials
** Donations for laser time and expendables
** How to schedule time
** How to actually use the damn thing
* Discussion about ACL
* Fundraising for the remainder of the $4000 plus extra for expendables

====Done Items====
* Get someone who knows enough about structural engineering to look at the place we want to use the laser cutter at Noisebridge, and let us know if the floor can handle the 1,000 pounds weight of the machine.
* Raise $4,000 for shipping, import tax, and warranty maintenance charge. This will get the laser to us, and give us full support from Kaitian.
** We've raised about $1500 so far
* Build a room for it, with some sound insulation and ventilation that can handle the fumes.
** The laser current lives in the Sparkle Forge.
* Come up with a plan for the room, and raise funds for buildout of the room.
* Review what else needs to happen to get the laser installed and the area in the Sparkle Forge it sits in happy
* Source some computer gear and a new monitor
* Some work to better figure out the laser software
