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 needs maintenance work. This manual gives instructions on how to clean the extruder motor pulley.

M Series Printers Maintenance

M Series Printers Maintenance

Zortrax M Series includes two printer models right now: M200 and M300. These printers remain similar in terms of design and technology. The most important difference is their size: M200 with a 200x200x180mm workspace, whereas M300 with 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 maintenance work. In the case of M300, these procedures look the same.

Unloading the Material

From the menu choose “Material” and then “Unload the material” option. The extruder should start to heat up automatically. Once the extruder is hot, the motor will start to unload the material.

Unplugging the Power Cable

Turn off the printer and unplug the power cable.

Unplugging the Extruder Cable

Unplug the extruder cable.
