Fillament always blocks after few hours operation

  • Hello guys,

    I am an owner of a new Crelaity Ender 3 V2 printer. This is my first 3d printer. I face a problem which I do not know how to debug. While trying to print a very common filament support with PETG after few hours of work jsut before finish, the feeder motor starts skipping because the fillament blocks somewhere inside the extruder. I tried several times, always the same result. I clear the extruder and try again. The first layer is OK, the other layers seems to be also OK, but at some point the fillament just block and I can not find a possible reason for this. Any ideas?
