Hi, I just finished again a RatRig 400 but my Motors never run well .
After a lot tries and different steppers i get all running until one Motor , after trying switching Motors / drivers I tired the board also in an Running RatRig 300 with the same issue . So all looks like the Stepper driver Port is broken .
Next days will Test the board from the 300 in the 400 but so long i want to try to change the slot of the stepper Driver .
Does anyone tell me how to do it ?
