The extruder motor is responsible for loading the material into the hotend.
Therefore, if you can hear a clicking sound coming from the extruder motor during
the material loading or printing, or if the material gets blocked in the duct in the
extruder, at first you should carry out extruder motor maintenance. The
instructions are available in the manual: extruder motor maintenance.
If the maintenance work does not help, follow the steps from this manual to replace the
extruder motor.
The following manual shows the M200 repair work. For the M300, these procedures are
the same.
