Swapping the motor at the Axis is a troubleshooting method that is meant to isolate the cause of a problem with the motors.

After swapping the motor:

  • If the problem stays on the same axis/motor, that indicates the problem is with that motor.
  • If the problem moves to another axis, that means the problem is before the motor cable/motor.

To perform this procedure:

  • Lock out power to the machine
  • Using a silver marker or tape with writing on it, label the motor's current axis.
  • Perform the procedure to Remove the motor for both motors that are to be swapped.
  • Perform the procedure to Install a motor for both motors in their new positions.
  • After performing this swap, be cautious when enabling the machine, ready to engage the E-stop at the first sign of trouble.

After performing this procedure, use the result to progress with your troubleshooting by returning to the document that instructed you to perform this procedure in the first place.

Note: If you are going to be working with swapping the Z axis, care must be taken to ensure that the set of cables that will now physically lead to the Z motor have the green and white wires hooked into the proper terminals on the circuit board. This may require you to leave the green and white terminals plugged in while you move the black and red terminals elsewhere.
