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.
I don’t know what to do…
Thank you very much
