11.3 Clogged / jammed extruder
- Material clogged in extruder can cause problems with the printing or with the loading of a new filament.
- Heat the nozzle, remove the filament from the extruder and cut the rod cca 10 cm above the damaged part.
- Next step is a cleaning of an extruder. There is a service hole on the left side of an extruder where you can access the hobbed pulley (pict. 16).
- Clean the hobbed pulley then heat the nozzle and load filament.
- If a problem persists you have to clean the nozzle.
