I'm new user to Mach3 however my machine has been running just fine until last week. I used it 1 day and then the next day turned it on to use it and the Y axis wouldn't move. The computer screen shows it's moving and thinks it's moving but the CNC will only move the X and Z. I've replaced the cable just in case but that had no effect. I've gone over all my settings and nothing seems to be different. What would cause the Y axis to stop moving for no reason? I'm stuck.
