Filament size change after a time under pressure to 1,98 mm normally it should be 1,75. After expanding geometry of filament become impossible to push it back to hotend. First i try to close retraction, but didint worked out. When this happens extruder makes sounds like ‘clik clik’ then stops feeding. To countinue printing i need to take filament out and cut that area then it countinues fine for a while. I try many things like wedge, heat, filament chance etc. etc. but nothing worked. Filament stucks in guide tube which places in coller profile and stucks there.
Ps. I cannot upload photo and video becouse i am new in here .
