Talk:Laser Cutter/Full Spectrum Laser 40W

2012-06-26T02:27:25Z

BeriAlpha:

I picked up some Masonite for use in the laser cutter. It works well for raster engraving, but it's too dense for vector; multiple passes didn't come close to cutting through the material.

I wasn't sure where to put this on the main page, since it looks like Masonite is totally suitable for raster and totally unsuitable for vector.

Glenn from Dallas Makerspace again.

For a fire extinguisher we use a 9 oz paintball CO2 tank with one of these nozzles from Ebay works great and its cheap to fill at any sporting goods store that sells paintball stuff. The tank costs about $12, the nozzle about $14 and to fill is $3.

FYI from Dallas Makerspace 2/25/11

We have had one of these lasers since 08/2010 and we love it. I have put together a training presentation on how to use this laser. See http://dallasmakerspace.org/wiki/Laser for details, Glenn Pipe

Hi Corey,

I received your information from Amy @ the Epilog factory in Golden. I would like to talk to you regarding your interest in the laser system and to discuss more about the ideal laser for the environment in which you are looking to place the laser. If you could please provide me your contact #, I would be happy to call you, or if you prefer, you can contact me at any of the #’s listed below.

Thank you again for your interest in the Epilog laser system!

Update 5/14/2010 [[User:Coreyfro|Coreyfro]]

I agree leasing may be the best option because there is a degree of service that is required that may be best left to the vendor. It also means we can experiment with off brand systems without much buyer's remorse.

I have experience with a shared laser engraver at Techshop and can bring some logistical lessons learned from that experience (once I resuscitate those brain cells.) We can see if Epilog is interested in giving us the same deal that Techshop got since NB and Techshop at least have the "den of future customers" aspect in common.

Check this out, campers:

http://www.lightobject.com/Solo-Desktop-40Watt-CO2-Laser-Cutting-Machine-Pro-Support-Mach3-KCam--P399.aspx

That's just suspiciously cheap. But hey, we know from gcode, right?
(We use gcode to drive the [[MaxNCMill]] and have several tool paths up).

And it's big enough to make a Makerbot.

It seems to have (some) spare parts available:

And a bigger brother (still cheap):
http://www.lightobject.com/Professional-40W-CO2-Laser-EngravingCutter-with-DSP-Controller-CorelDraw-AutoCad-lover-P299.aspx

BUT: After several bad experiences, I ([[User:Jtfoote|Jtfoote]] 05:23, 13 May 2010 (UTC)) am considerably less gung-ho about shared equipment at Noisebridge. I find myself unwilling to lead an acquisition, and I have substantially reduced my pledge. It would still be a great thing to have, but I am unwilling to commit much energy to this.

Update 12/15/2009

The laser cutter issue has been revived. We may be able to lease one for around $150/mo. Make a pledge below to help make it happen!

Update 11/14/2009

[https://www.noisebridge.net/pipermail/noisebridge-discuss/2009-September/008292.htmlm September 09 thread] on laser cutter petered out, but the [https://www.noisebridge.net/pipermail/noisebridge-discuss/2009-September/008384.html NYCR post] seemed very informative.

There had been talk in October of [https://www.noisebridge.net/pipermail/noisebridge-discuss/2009-October/009301.html laser cutter access outside NB] but since then it's been all quiet on the laser front.

Any news? --[[User:Hurtstotouchfire|Hurtstotouchfire]] 13:59, 14 November 2009 (PST)

Just in: I asked Bre Pettis of NYCResistor (who makes a living on his) for advice. Here's his response:

> Minimum: 35 Watt Epilog Mini. 12x24 Machine + Filter + Tax = 20K

> Very Desirable: 60 Watt Epilog. 24x36 Machine + Filter + Tax = more than 20k.

> We wish we had gotten a more powerful machine, but because we didn't know better and it's a lot of money, we went with the mini.

> Don't get a chinese off brand machine. They are cheap and well, cheap.

Update 6/2009:

From grey,

Prices are coming down; and some decent units are out there.

A used Epilog I've been told can be had for around $5000.

However some of these random no name Chinese brands are undercutting that -new-. Matt Westervelt in Seattle recently got a 50W unit from Redsail for about $3000. In a similar price range, Jeri Ellsworth in PDX ordered a JCUT 3040 with a 60W laser bulb after some haggling. Ebay has some very small engraver units for $1000 (dubious quality) and Jake said he saw some units for as low as about $250 in Shenzhen (presumably similar to that low end engraver, questionable quality).

If we can collect information here about some different viable models, how much space they take, how powerful they are, what their surface area is, software compatibility, etc. And can determine what looks good - let's see what we can do.

I've got a close friend in HK who has dual Chinese & HK license plates and if we have a specific model he may be able to hunt it down and slow boat it to us for some costs savings. Maybe not, but it's worth looking into. -grey

There are rumors of Epilog having a rent-to-own program for what sounds like very reasonable monthly rates. Does anyone want to follow up on this?

Trip to Shooting Range

2012-03-28T19:01:35Z

BeriAlpha:

There is some interest in a field trip to a shooting range to shoot guns in a Safe and Orderly manner. If you're interested, list your name below, along with any time restrictions and whether you are able to drive a carpool. No previous knowledge or experience is required. If you always wanted to try shooting a gun, this is a good opportunity for that.

==Bay Area Ranges==
===Jackson Arms===
Jackson Arms is an indoor 25 yard range, about a 15 minute drive from 83c. They require that an experienced shooter be at each lane, but an experienced shooter can share their lane with two or three beginners, provided that the experienced shooter passes a safe handling test and signs a form taking responsibility for the actions of the beginners they're supervising. I've gone there with large groups before and they've been accommodating and friendly. They have fun stuff to rent, and I think it's a great place to learn.

Business Hours:
Open 7 days a week
Closed on Thanksgiving and Christmas Day

Monday - Friday: 11:00am - 9:00pm
Saturday: 10:00am - 9:00pm
Sunday: 10:00am - 7:00pm
Hours are subject to change without notice.

===Chabot Gun Club===
My favorite range in the bay area is the Chabot Gun Club range in Chabot national rec area in the east bay. It's a gorgeous outdoor range in parkland, but a bit of a drive, and only open when weather permits. They don't have rentals, so we'd need to bring our own supplies. The longer ranges make rifle shooting a lot more interesting than it is at Jackson. The longer drive, occasional fogged-out days, and lack of rentals makes Jackson the easier option however.

[[User:noahbalmer|Noah]]
===Pacific Rod & Gun Club===
On Lake Merced in Daly City.

== Interested Parties ==
[[User:EmbeddedLinuxGuy]] would strongly prefer an outdoor range such as Pacific Rod & Gun Club vs. indoor lanes like Jackson Arms. I would be willing to drive up to two hours into the sticks to make this happen.

[[User:tooluser]] yes please. Plus one more, my wife. Can drive.

ToniCarra - Yeehaw lets go shoot some guns, I have a car, anytime!

[[User:rachel|Rachel]] (have access to shared cars so can drive one carful)

[[User:Mlp|Meredith]] (I own a handgun and can teach fundamentals)

Daniela - would prefer to not drive
[[Category:Events]]

Cristina - I am free during the week after 5:30; I do not drive nor have a gun but I am more than happy to use one. I call shotgun!

[[User:skyex|skye]] (i have shot previously but only with a rented handgun. more experience would be fantastic.)

[[User:Jtfoote|Jtfoote]] Been meaning to do this for YEARS!

[[User:Arcanology|Al]] - Can I bring my Taurus 9mm?

[[User:AlexPerez|Al]] - I will bring my Soviet-era [http://7.62x54r.net/MosinID/MosinM44S.htm M44] unless otherwise directed :)

[[User:jstockford|jim]] - jackson arms does not require previous training. they have a policy not to rent guns to people who come in alone without a gun. solos with a gun or parties of two or more are okay. there's a reason. i have a car that can seat four (including me).

quinn - i'm interested, and have shot at jackson arm a bit as well, but i don't have my own gun. i have trained a n00b there.

[[User:Michiexile|Mikael]] - Interested, but never did anything ever. No car, no guns, no experience.

[[User:savaki|Matt]] - Uh huh uh huh uh huh. Count me in.

[[User:Jof|jof]] - Have only done prone target shooting with .22 rifles.

[[User:Kripto|Mark]] - I don't own any firearms, but I've shot many calibers of handguns. (At Jackson Arms) No Car, will need a ride.

Jeffey Malone - I've an interest and a car that seats 4 passengers.

[[User:Rigel|Rigel]] interest, have no car, have no gun, but have shot them a fair bit as a lad so im not a n00b. fridays and saturdays are bad for me, but sunday or during other times of the week are good for me.

[[User:noahbalmer|Noah]] - I own a rifle and a pistol, and can teach

[[User:Christie|Christie]] - Trying out a shotgun recently, I was reminded how much practice I could use. I've tried a variety of different handguns as well. I have the van of legend that allows for an unspecified number of people rolling around in the back.

[[User:AlSweigart|Al Sweigart]] - I'm interested.

David Stainton - I'm interested and I have two rifles.

Tracy Jacobs- count me in, I drive too much, don't shoot nearly enough, have truck seats only 2

[[User:Bifrost|EvilBifrost]] - I own a few paperweights.

[[User:Dichro|Mikolaj]] - I've been to Jackson Arms twice with friends, done the safety course each time, but haven't wound up shooting all that much either time.

Sai - Interested; only experience is a boy scout range once, several years ago.

Jesse Welz - I have lots of experience to offer and a big fun WII Russian gun to shoot.

Metatron/Mark - I'm in the area from Feb 02 to 09 coming in from the UK (basically if you want to shoot here you need to be rich or a criminal) I am planning on visiting the space and would love to go for a shoot. I've used shotguns and air riffles but that's it.

[[User:Helyx|Helyx]] I'm definitely in on this!! I haven't shot in awhile, and have no equipment, but i have a car! There is also an outdoor range in Richmond as well, though I'm pretty sure they don't do rentals either.

[[User:Ergomatic|steiny]] Me too. I was a pistol and rifle instructor in the USMC in the early '90's...I can coach you if you are a beginner, help you if you are nervous, or want to correct bad habits. I live in Richmond (east bay) and can drive. Count me in!

Eve - interested, can drive, can bring own, seeking guidance on proper maintenance. Hours flexible.

[[User:BeriAlpha|Barry]] - I'm interested. Chabot Gun Club seems like it's my style. I taught the Rifle Shooting and Shotgun Shooting merit badges for the Boy Scouts for six years; I could do a basic safety and technical lecture. I have one interesting rifle I'd be happy to bring, a 1912 SMLE. It's very enlightening to use a gun that's a century old, and still extremely reliable.
