Hi! Your Pinyaaah interchangeable-head printer is amazing! The key parts seem to be the mobile head designs, the holder design, the arm dock design, and the software to make it all work. Can you tell us anything about how you built this? Did you design it all yourself, or are there deign files somewhere on the web. Thanks!
Sorry for the delay, I did design the holders and docks, but not so great, the software is just a small mod into Marlin,and after that lots of custom GCodes.
