Got this awful noise coming out of the printer after a failed print. It’s really yanking on the filament but nothing’s happening - any ideas?
Can’t extrude or withdraw the filament either.
Clogged hotend or drive gear.
I usually unscrew the nozzle and try to extrude , if that works then cool down, replace nozzle and off we go.
If still troublesome you may have to clean out the drive gear or maybe the clog is in the heatbreak and more dissasembly is required.

(when i say “usaully”, its probably happened ever 5kg or so)
Thank you! The blockage was in the uh… bit? that joins the nozzle to the gear drive.
