The nozzle is an element used to direct a flow of material throughout the entire printing process, allowing the printer to form the desired shape of a model. If you encounter problems with extrusion during either material loading or printing, the nozzle may be clogged and require cleaning or even replacement. Also, the nozzle needs to be replaced if you notice burn marks or a visible lack of material in your print’s structure.
|The following manual shows the M200 Plus repair work. For the M300 Plus, these procedures are the same.|
