The material endstop is the device placed at the back of the printer, which detects the presence of material and reacts when it runs out. If during the printing process a spool of material is finished, the material endstop will automatically make the printer pause the printing and allow the user to load new material. Therefore, if the material endstop in your device does not work properly, you should replace it. Follow the steps from this manual to carry out the whole procedure.

The following manual shows the M200 Plus repair work. For the M300 Plus, these procedures are the same.
