This is a real head scratcher. At one point in time I had my CNC setup with a bitsensor controller board, and it worked just fine. Then after my cat walked all over the keyboard one day it stopped working. Well, the part that stopped working was the coolant relay that I set up to operate using M7 and port 4. I was able to get that working, now I have a problem with the X and Y axis. They both only move in 1 direction, and I can't seem to get them to setup correctly. Any ideas out there?
