The extruder PCB is a part to which all extruder components are connected. Therefore, if any of these components malfunctions or does not work at all, at first check a given component for proper functioning. If everything seems to be working properly but you notice hanging strands on your model and the printer overheats, consider replacing the extruder cable. If these solutions do not help, you can be sure that the PCB is damaged and 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
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.
