The extruder bearing supports extrusion by pressing the material to the extruder
motor sprocket wheel during loading and the printing process. Therefore, when
the material in your printer is not being extruded when loading or printing, or the
sprocket wheel is making clicking sounds, the extruder bearing may be faulty and
should be replaced. Follow the steps from this manual to see the correct
replacement procedure.
If the material is loaded into the extruder, unload the material using the “Material” ->
“Unload material” option in the printer menu.
The following manual shows the M200 repair work. For the M300, these procedures are
the same.
