7.2.2 Clogged Nozzle Cleaning

Method 1:
1. Heat the nozzle to the matching temperature of the filament used;
2. Pull out the filament guide tube, press the handle and pull out the filament;
3. Observe whether the head of the filament is bent. If so, cut off the bent part of
the head of the filament, then insert the filament guide tube and the filament
into the nozzle again, and click the [Load], and the nozzle will re-extrude the
filament.
Method 2:
Heat the nozzle and insert the unclogging pin tool into the throat and the nozzle to
extrude the filament inside the nozzle.
When operating the extruder, the power supply must be
disconnected.
