The PCB Mill   -   Homemade CNC Milling Machine

In pursuit of a cheap device that could help me produce my own Printed Circuit Boards, I built the PCB Mill. It was controlled by two microcontrollers and communicated with the PC to download instructions. I also created a layout program in C++ to convert HPGL files into a format that the milling system could understand. The final product worked well, except for a slightly sinusoidal pattern caused by a bend in the guide rods.

Feel free to read the PCB Mill project writeup, and check out the video overview of the system working (29MB).
