T-Rex Plans

The plans I used are available at www.makecnc.com, this is a good resource for
Hobby CNC users, please note I have no affiliation with this company, I came upon them after a google search.

The plans come in several formats, for me I used DXF so I could import them into AutoCAD.

Modifying Plans

My first steps was to modify the plans for use with the current wood stock I had available which was sheets of 3mm – 3.4mm Plywood at 300mm x 210mm.

In AutoCAD I drew a rectangle of 300mm x 210mm to represent the wood stock, I then placed all of the components into one of these rectangles, in my case I needed 4 rectangles.

Hi, this is not an Endurance Laser. It's a Robots Everywhere L-Cheapo Mk3. You can tell by the holes on the heatsink. I make them myself and have been (with improvements) since 2014 when the L-Cheapo kickstarter was featured on HaD ( https://hackaday.com/2014/06/02/the-laser-cutter-attachment-for-a-3d-printer/ )

You can buy the current version at www.3dsupplysource.com but since you're reading this on Hackaday, you'll probably want to build it yourself from our free resources available at http://robots-everywhere.com/re_wiki/pub/web/Main.LCheapo.html

Please note that "Endurance Lasers" used to be our reseller, but is currently manufacturing new units for sale, against both my consent and the Creative Commons Attribution Noncommercial Sharealike license that i use to release my schematics with.

Help support Creative Commons!

Also, of course, I am very happy that you like my laser :)

As the Laser was purchased from Endurance Lasers I cannot comment on any disputes between yourselves regarding issues you stated above.

However regardless of source and the point of the article this is a very good laser and its to show that Diode lasers can be an effective tool for model makers.

Thanks, yeah came out much better than my initial thoughts, the laser is great when I want to do some quiet Cnc work.

Are you sure? yes | no

Good work. How many pass to cut? What is the material and tickness? Thank you.

Are you sure? yes | no

The wood is 3mm - 3.4mm plywood and it was 8 passes to cut.

Are you sure? yes | no

Wow, that did come out really nicely. Congrats, now you have a CNC mill *and* a laser cutter!

Are you sure? yes | no
