The Z-axis coupler 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 couple needs to be replaced. Before replacing
the coupler, make sure that the screws on the coupler are properly tightened.
More details can be found in the manual.
If the screws cannot be fully tightened, follow the steps from this manual to replace the Z-
axis coupler.
The following manual shows the M200 repair work. For the M300, these procedures are
the same.

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.
