If you have an Etch a Sketch in the closet collecting dust, the Etch CNC may be an interesting project that could put it back into use. The circuit board is my own design, using a ULN2803 per motor to supply approx. 0.3 amps per winding. The power supply is a standard AT hard-drive power connector, with the +12V used to power the motors. It’s a simple constant-voltage L/R drive. I made the circuit board using EAGLE, and milled it on Chris’s real CNC milling machine (which is powered by EMC and AXIS, of course). “

That looks pretty cool, you should post a video

This is so awesome! What a great way to learn CNC without spending a lot of money on Stepper motors and all that jazz!

Very cool is there a parts list out there?

DIY HACK - Etch CNC
Check out this cool etch CNC. Actually we were thinking of making this too, but since it’s already
made, we can learn from it and make it quicker. Awesome!
I am using a retrofit machine that fit within my budget. It’s a 2-axis machi…

Nice project. What software is used to run it?

Is that a com port?

Hey Zadamaxi,
Looks like a parallel port.
