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 extruder, the extruder motor needs replacement. This manual shows how to replace the extruder motor.

M Series Printers Servicing

m200m300.png

The Zortrax M Series includes two printer models right now: the M200 and the M300. These printers are similar in terms of design and technology. The most important difference is their size: the M200 has a 200x200x180mm workspace, whereas the M300 has an increased 300x300x300mm workspace.

Therefore, maintenance and repair work can be carried out in the same manner with both models. The following manual shows M200 repair work. For the M300, these procedures look the same.
