I have a Bridgeport R2E4 CNC milling machine that I just purchased from a local community college. After setting the machine in place I tried to start it and the control panel gave me an error that the axis drive would not enable. I checked the control panel and found that the RC circuit across one of the axis starter coils was blown. I replaced the RC circuit and it burn out again. I cannot find any shorts in the circuit. The coil checks the same as the two remaining axis coils check. Does anyone have any quick things that I can check?
Thanks
Rick
