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.
Yeah, ok, that looks pretty crushed.
Did you maybe “release” the extruder spring tension adjustment screw in the wrong direction? (Maybe screw that screw to the limit in the other direction and check if that removes the issue)
If that doesn’t sove the issue, there are only two possibilities:
I dismanteled the extruder. And swapped filament, I think I fixed it.
Nice! Yeah, pre-assembled extruders are sometimes assembled wrong. Had it before.
