More Laser Cutting Learning

So, I’ve been thinking a lot about the makerspace this year. One of the tools I have been working on a lot recently is the laser cutter/engraver. I am a beginner with Adobe Illustrator so that has been a challenge.

I don’t know where I first heard about it, but I kept hearing about taking 3D printer files and laser cutting them. I also then saw these fun bots made by RoboMustache at a STEAM/Maker event with my personal kids. Seriously, how cute are these little things? I put these two ideas together and decided I needed to learn to design the shapes that I would need to create my own RoboMustache-inspired closed shape in TinkerCad, which I am better at, and then figure out how to cut them.

I googled how-to change 3D printer files to laser cutter and found this directions from Make Magazine. After looking at Methods 1 and 2 and decided on Method 2, because 123D-Make is free software. Win.

I know the directions were step by step, but still it’s a lot of translating files. The more translations, the more places to mistranslate. After sorting out a few issues with depth/height of the .stl files and scaling in 123D-Make,  I had a beta version. After a few more tweaks to the TinkerCad design, I had a solid box (small on one right below). I have to say that I felt pretty proud of myself getting it all figured out. It was not hard, but there was also no one around to go to for support. Plus, I have now explained it to others.

Here are my first boxes.

The one thing I haven’t figured out is how to get the DXF file from 123D-Make to come in to Illustrator the exact size they were created in TinkerCad. I’m not sure where I am missing a setting. With scale settings to set as the files move from each program to the next (.stl from TinkerCad–>123D-Make–>export as DXF–>open in Illustrator–>scale to size–>cut) I have a lot of combinations to try, and so far I have not dedicated myself to keeping track of attempts and results.

Onward!
