The files below were created using ExpressPCB, a free pcb studio. They replaced the large, messy proto-shields that I developed to handle the safety systems, the motor driver connector expansion, limit switches, and finally the pause function when the doors open. The board that stacks on top of the Galvo/Laser driver board contains some extra circuitry that will allow me to add extra functions in the future.

As I complete the electrical schematics for the entire machine, I will add them here for download
