The nozzle is an element used to direct a flow of material throughout the entire
printing process. If you encounter problems with extrusion during either material
loading or printing, the nozzle may be clogged and require cleaning (see the
manual – nozzle cleaning) or even replacement. Also, the nozzle needs to be
replaced if you notice burn marks or material deficiency in the model’s structure.
Follow these steps in case cleaning does not help.
The following manual shows the M200 repair work. For the M300, these procedures are
the same.

Unloading the Material
From the main menu select Material and then Unload the material option. The extruder
will start to heat up automatically. Once it is hot, the motor will start to unload the
material.

Nozzle Removal
Unscrew the nozzle counterclockwise (when viewed from below). Use the nozzle key
from the Starter Kit box. Removing the nozzle should take place while the extruder is still
hot. When the nozzle is loose, remove it using pliers.
