Another drawbot with interesting positioning


#1

Bart Dring, of makerslide (and laser) fame, has another cute little drawing robot. Of interest is his firmware that uses intersecting circles for positioning to save cpu time.

It runs on grbl ported to one of those ESP whatever 3 dollar (+/-/?) wonders, although tfa mentions a 20hz update rate
