I definitely get filament out of the nozzle.
Tension of the feeder is in the middle position.
Temperature is 210°C changed that to 220°c without result
I already replaced the printcore. Problem remained
I have to check the printspeed. I assume it's the default one.
Keep you posted!
Strange, so filament is extruding during the loading process and you get definitely filament out of the nozzle?
Check if the tension of the feeder is in the middle position, you should see a small indicator.
It seems that for whatever reason the filament cannot be extruded during your print and that's the reason why feeder wheel grinds your material. So we have to check why. Do you print with default speeds? Printing a way too fast could cause the issue. Printing too cold too.
You can also check if you get the same result with another print core. You should have another AA 0.4 in the box.
