We've been developing and iterating an open-source CNC platform called Piccolo. The basic premise was this - make a low cost, Arduino powered, hobby servo driven, 3-axis CNC platform, entirely digitally fabricated and simple enough for a complete beginner to assemble and start learning about CNC, and that is small enough to fit in the palm of your hand.
This talk will introduce the design, show a few demos, and explain the various issues and surprises we negotiated along the way. I'll go into depth about servos and in particular hobby servos, and a few unexpected things we discovered from testing various makes and models. I'll also go over a few things you may not know about laser cutting.
I'll also cover everything you need to know for making your own Piccolo!
