The extruder PCB is responsible for transferring signal and voltage from the
motherboard to all extruder components, including fans, heater&thermocouple
and extruder motor. Therefore, if you notice problems with the extruder, such as
extrusion or heating issues, or if the extruder motor sprocket wheel is making
clicking sounds, at first you should check whether all components plugged into
the extruder PCB are functioning properly. If everything seems to be in order, but
the problems continue, the extruder PCB should be replaced. This manual
provides the correct replacement procedure.
If you have the extruder PCB v1, you also have to replace the hotend and
heater&thermocouple.
The following manual shows the M200 repair work. For the M300, these procedures are
the same.
