Thingiverse user BenJackson designed a bracket and two gears that allow you to add numeric ontrol capability to your Etch-A-Sketch.
What can I say? I’ve never been able to draw anything with an Etch-a-Sketch. I won this one in a Christmas gift exchange some years ago and hung onto it with the idea that someday I’d CNC it.
The stepper motors are 7.5 degree Airpax steppers I got surplus many years ago. It turns out those mounting ears are actually NEMA 23 compatible so this should work unmodified with “square” steppers as well.
