K1 Max not extruding properly

Flagship K Series
1

Goodmorning to everyone, I have a K1 Creality.
Since a few monts during the printing, I see that during the print the filament no longer comes out of the extruder in a continuos way but comes out in sections and more precisely in points… and it happened randomly during the print. Sometimes after this problem the filament no longer comes out of the extruder and the printer fails, sometimes this problem persist for 1/2 layer and after that the filament return coming out of the extruder continuously.
I have changed 2 times the extruder, I changed the extruder board … but nothing happened.
During the problem I see the motor is working but the filament doesn’t move.
I use my k1 without lid and the door open to avoid high temperature.
The printer always works with a room window open to change the air and improve the coling.
You can see in the photo a cup in which after 1 /2/3 layer problem the print restart, in the other photo the print fails and u can see a discontinuos print, some points of filament around the piece before failing.

Thank you very much

I am not sure if this is the problem but you could make your offset a little higher it could be that because it is to low the filament cannot be laid down properly the first layers.
In printer settings you can set your Z offset to e.g. 0,10 mm and try printing something small to test this.

Thank you! I’m trying your solution

Goodmorning @tjan , I replace the extruder (the component with gears) and the printer restart printing in the correct way…probably there were low pressure between the gears and the filament slipped
