CNC Machine – Part 4

I didn't get as far this weekend as I had hoped too - I've got most things wired up, but I still need to make patch cables for the motors and limit switches. The Arduino is programmed and I tested the spindle on/off control by plugging a fan into the relay-controlled outlet. So probably only a couple more hours of work before I can test that each of the axes moves. After that it's just a little axis tuning, and getting my software workflow figured out.
