That helped. Thanks.
I think I have the same problem as PeterH on this thread. The motors were running fine, and now suddenly they don’t respond at all. Repetier is talking to the board, I can drive the fan, heat the extruder and bed, but the motors are not responding and no LEDs are visible by the motor drivers when I try to send manual commands to move them. Here is a log of the commands sent to the board when trying to move the X, Y, Z axes and extruder manually, but with no response from the motors. Does this need a new board?
Thanks.
