¶ Observation
The printer launches a motor self-check program each time it is switched on. The control board applies voltage to the motor and checks the current passing through the motor. If the current is unusually large, it indicates that the motor is short-circuited.
The error of motor short circuit may be caused by the following reasons:
- Motor failure
- MC board failure(X1/P1 Series: MC board, A1/A1 Mini: Main board)
¶ Troubleshooting
¶ Safety warning
Please turn off the printer and disconnect the AC cable during operation
¶ Actions
¶ Step 1: Expose the MC board and swap the plugs of Motor A and Motor B on the MC board.
Please refer to this Wikis to remove the printer back cover and swap Motor A and Motor B plugs.
X1/P1 Series Wiki
Connector: 2- Motor B, 3- Motor A
¶ Step 2: Restart the printer and observe the change in the motor short circuit fault.
- Suppose the original HMS error was "Motor-A has a short-circuit. It may have failed". After swapping Motor A and B, the new error is "Motor B short-circuited. It may have failed", that is, the fault changes with the switch of the motor. Root cause: Motor failure.
- If the fault remains unchanged, that is, the fault does not change with the switching of the motor. Root cause: MC board failure.
¶ Step 3: Repair
- Motor failure
please refer to the following Wiki to replace the motor.
X1 Series Motor
P1 Series Motor
A1 A Motor
A1 B Motor
A1 mini A Motor
A1 mini B Motor - MC board faulty
please refer to the following Wiki to replace the MC board.
X1 Series MC Board
P1 Series MC Board
A1 Mainboard
A1 mini Mainboard
If HMS reports “motor Z has a short-circuit”, this is usually due to the motor being broken but there is also a small probability that the MC board is broken.
