ETCH CNC

at 5:16 am. Filed under Complex Hacks, Computer Hacks, Electronic Hacks

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.

“I am using a retrofit machine that fit within my budget. It’s a 2-axis machine with approximately 170x130mm travel.

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). “

    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!

    the top picture has a different controller, not a UNL2803? Interested in controller software used. Would like to use EMC2 with simple UNL2803 board like this.
