My ender 3 v2 extruder is crushing the filament and snaps thus the printer fails to print. I have adjusted the extruder tension, nothing has changed. I also upgraded to a 0.6 hardend steel nozzle and I checked if it was the nozzles temperature, that made no difference.
I dismanteled the extruder. And swapped filament, I think I fixed it.
Nice! Yeah, pre-assembled extruders are sometimes assembled wrong. Had it before.
