Z-Axis Motor Replacement

The Z-axis motor is responsible for the platform’s movement along the Z axis. Therefore, if the platform does not move at all or it moves with difficulties and makes unusual noises, the Z-Axis motor needs to be replaced. Before replacing the motor, make sure that the screws on the coupler are properly tightened. More details can be found in the manual.

If tightening the screws does not help, follow the steps from this manual to replace the Z-axis motor.

The following manual shows the M200 repair work. For the M300, these procedures are the same.

Unplugging the Power Cable

Turn off the printer and unplug the power cable. Wait a few minutes for all the capacitors to discharge.

Changing the Printer's Position

Grab the printer’s housing and change the printer’s position so that you can easily access the bottom plate.

Unscrewing the Bottom Plate, part 1

Unscrew the screws that secure the bottom plate on one side of the housing. Use a 2.5mm Allen key.

Turning the Printer

Turn the printer over.

Unscrewing the Bottom Plate, part 2

Unscrew the screws that secure the bottom plate on the other side of the housing. Use the same key.

Separating the Bottom Plate

Separate the bottom plate from the printer and unplug the bottom fan cable from the motherboard.

Providing Better Access to the Z-Axis Coupler

Unfasten the two extruder cable straps and unplug the cable from the motherboard. Next, unfasten the third strap. Place the extruder cable between the power supply unit and the housing. Finally, grab the cables next to the motherboard and fasten the strap.

This step is not necessary to follow, however it is recommended so as to avoid the risk of damaging the cables and to get better access to the Z-Axis coupler.
