I saw the video about this, very cool! Couldn't help but notice that it looks like the pad points are visited in the order they come from the gerber, and that order is a bit all over the place. I had written a gcode generator for a pen plotter way back that sorted the points to visit them a bit more efficiently. Seeing the video had me rethinking strategies for this and wrote a blog post about it that has a js implementation. Maybe you'd find it useful to save a bit of movement time.
