Issue(s):
- When the problematic motor is removed from the machine but still connected to the controller, jogging the axis does not make the motor shaft move
- Only one of the motors (open loop / LongMill) is not moving, the rest of the motors are OK
- Adjusting the mechanical components on the LongMill does not improve motor movement
Resolution:
- Remove the motor from the machine so you can see the motor shaft, but keep the harness on
- Use the attached troubleshooting chart to identify whether it is the motor, motor harness or controller causing the issue
- Based on the results from the chart...
MOTOR:
should be replaced.
HARNESS:
should be checked for loose wires, broken leads and inconsistent wire patterns (should be the same on every harness). If these look fine or adjusting these don't change anything, harnesses should be replaced.
CONTROLLER:
SLB - should be replaced.
LongBoard - first check that all the DIP switches are properly seated in the correct orientation (up-down-updown). Then ensure the Arduino is fully seated on the control board. If these are fine or adjusting these don't change anything, replace the controller.
