Are you trying to calibrate though a hot nozzle or with the bowden tube disconnected?
You may also need to adjust the tension on your extruder gear.

I heated the hotend to 180°C with the nozzle for my PLA filament. Do you have a reference for adjusting the tension of the extruder gear? Seems logic for me but I have no idea

That's way too cold, and you were probably trying to calibrate too fast. I always calibrate my e-steps with the bowden or nozzle removed.

Extruder gear tension is tricky. Too low tension can cause it to skip over the filament, too high tension can cause the motor to lose steps. If you can *see* the filament being ground off by the wheel, you'll probably need more tension (if it's adjustable at all on your printer).

Thank you for your hints I'll try it later again, which temperature do you use?

Cold, with the bowden tube (bowden) or nozzle (direct drive) removed ;)

Also, go back to 80-ish steps/mm for now
