Hello there. I'm Andy, living in South Wales near Swansea. I have an EMCO F1 CNC mill which has been converted to run controlled by Linux. I need help to get the machine running again as after recently moving house the stepper motors all refuse to run. The spindle motor runs but not the stepper motors. I've checked the voltages coming out of the power supply board and they appear to be OK and I'm now at the limit of my electrical knowledge.
