● The next step is to clean the extruder. There is a service hole on the right side of the
extruder where you can access the hobbed pulley (pict. 41).
● Clean the hobbed pulley, then heat the nozzle before reloading the filament.
● If a problem persists, you will have to clean the nozzle.

Filament is pouring out a little
If the filament doesn’t go through the extruder smoothly and only a small volume is coming
out, first check if the extruder fan is working properly and that the temperature is set correctly
(PLA 210 °C; ABS 255 °C, HIPS 220 °C, PET 240 °C)
. Also check that the filament was
correctly loaded into the extruder.
If that is not the case. Follow the instructions below:
1. Heat the nozzle according to the filament you want to print from. Load the filament
and push a
bundled acupuncture needle
(0.3-0.35 mm) into the nozzle from below
