Hey Guys,

Stumbled across this http://www.buildlog.net/blog/2017/08/the-polar-coaster-a-drink-coaster-drawing-machine/

the video is really interesting, I’ve not seen a bed move in a circular motion before to plot.

Cheers Rob.

Fixe the link.

That is easily the simplest cnc I’ve seen. Very clever. I guess the preprocessor converts a circular pattern to a rectangular one?
