The extruder bearing is responsible for the motor shaft rotation so if the extruder motor is not functioning properly or it makes unusual noises, this may indicate that the extruder bearing needs to be replaced. 

NOTE: If the material is loaded into the extruder, unload the material using the “Material” -> “Unload material” option in the printer menu.

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.
