3" MDF box - my first project

Post by Burke LaShell » Sun Apr 22, 2012 10:30 pm

I'm kinda proud of my first project (after Hello World). I designed a 3d box in SketchUp, generated the G-code with PhlatScript, and cut it on my ShapeOko.

Not too bad for a guy who couldn't spell CNC six months ago.

I posted details in the wiki projects gallery...

Very nice!! Any additional thoughts/lessons learned you can share? I think this is a great first project for actual cutting after doing the hello world.

Nice box! Did you account for the kerf of the cutting bit in SketchUp or elsewhere in your process? This is one of my lingering workflow questions. Also, what cutting bit and cutting speed did you use?

If you can deal with the dust, 1/4" MDF is a nice material to start cutting. It's cheap, easily available, cuts easily, and doesn't melt (like Plexiglas)
I think this is a great first project for actual cutting after doing the hello world.
Actually, I'd say that a 1" circle is a good first project. Then, a 1" circle inside a 2" square is a great second project. The box is a nice third project.
Did you account for the kerf of the cutting bit in SketchUp or elsewhere in your process?
Yes. Phlatscript has a place to enter the tool diameter. In this image, the black lines are the finished part, the orange is the tool path, and the green are the "tabs" that are left so the piece doesn't move during cutting.

Also, what cutting bit and cutting speed did you use?
I used a two fluted bit I purchased on eBay and ran it at 100"/min. Acceleration in GRBL ($8) set to 9.8. No problems.

What version of Phlatscript/Google Sketchup are you using? I've installed 8 and can't seem to get it to show up in Sketchup.

Huh, that's exactly what I've got set up too. Did you put the Phlatscript files in a separate folder or just dump the lot in plugins?
