¶ Replace Guide
- After disassembly the toolhead, loosen the two screws that fix the motor.
- Take out the motor, loosen the screws at the handle, remove the screws, washers, and the spring and nut on the back.
- Loosen the three screws on the fixing plate.
- Take out the fixing plate and the plastic gear, insert the new plastic gear, align it with the bearing hole position, and then place the fixing plate.
- Lock in 3 screws, adjust the position of the BMG gear up and down so that the plastic gear does not shake up and down when rotating. Lock in the Set screws on the handle side.
- After installing the motor, screw it in (make sure the motor wire points forward), and then adjust the position of the motor.
- Secure it firmly to ensure smooth operation of the plastic gear when it is moved, and then tighten the two screws of the motor.
- Insert the gasket and screws on one side, and on the other side insert the spring and nut. Tighten the screws, making them protrude 2 to 3 turns beyond the nut’s thread.
- Assemble the toolhead back together.
