Hi All,
Looking for some guidance on an issue with my mill. It's plugged in and when I turn on the power switch, the green main power light comes on. However there is no RPM display and obviously the spindle doesn't turn. I have read some posts about troubleshooting but I haven't read about this particular situation. Since I'm getting power at the switch, wouldn't this most like be at the controller boards? I checked the fuses, stop button, chip guard switch and they all seem to be okay. I don't see any burned spots on the boards but I have not taken them out yet. Any help on the next steps to troubleshoot this would be greatly appreciated.
