Baldor F391 troubleshooting
Posted: Fri 16 Apr , 2021 13:33 pm
Hello
I have a Denford Micromill 2000. I think I have blown up part of the driver board (the bottom one). Symptom: the X axis stepper does not move but only makes a whirring noise. If I plug the X axis cables into the Y axis socket (and vice versa) the problem gets transferred to the Y stepper. So obviously the motor and cables are OK.
The board is marked as Baldor F391 issue 2. Is there anything relatively easy I could try (eg replace a component or two?) Alternatively if I am trying to source a second hand replacement board, does it have to be issue 2 or will and issue 1 version work?
