Re: CNC Etch-A-Sketch, EggBot

Alan,

The simple thing is to use a parallelogram (think rear
derailler,10speed) on the "pen" axis...

Hi-tech would be to sense the surface, either by contact/retract (not
good as it marks up the egg!) or with a small "angular laser"
distance module...

Hope this helps.
