Hi, My CNC router has just stopped working properly. When I press the Y axis key on the keyboard of my PC, which runs Mach 3 software, the Y axis does not move, Instead of the Y Axis jogging, I just hear a buzzing sound. The X axis moves normally when jogged. When I swap the X & Y plugs that come out of the CNC controller box I get the same results except that I have to press different "Arrow" keys on the PC keyboard. It seems like it may be motor or cable connect problem. Any ideas?
Cheers Gary
