Maker Faire NY is awash with new and interesting computer controlled tools, but the most unusual so far appears to be Popfab, a combination router, 3D printer, and vinyl cutter able to collapse down into a suitcase.
Popfab is the brainchild of [Nadya Peek] and [Ilan Moyer] of the MIT CADLAB. With interchangeable heads for routing PCBs, 3D printing, and vinyl cutting. A conventional machine of this capabilities would have motors all over the place, but [Ilan] used a CoreXY system to make the stepper motors stationary relative to the frame of the machine.
The electronics are standard Printrboard and Pronterface fare, but it’s still a remarkable build that also fits into a suitcase.
Pictures of the machine, the XY system (good luck wrapping your head around that, but I can tell you it relies on the differential movement of the two motors) and the lovely [Nadya] holding up the plastic extrusion head. We’ll get a video up
tomorrow. after the break
