A print failed due to a filament problem. Not sure why because the roll was not stuck in any way. Now I can't pass the filament through the hole (where the motor sits). the filament stops. It get around 2 cm in, I hear a click and blue light turns on. Never had this problem before. I can get it in the other way but from for the lower end (where it should go in) it stops like it's blocked in the inside.
Does anyone know how to fix this? This was not an issue first when I loaded it before.
