I have been getting these lines where there seems to be not enough filament extruded accompanied by some clocking noises (not really grinding). Recently I got a few errors about stuck filament as well.

I did a few cold pulls but there wasn’t any debris to be seen and the three ends (cht) were clearly visible.

Noises, pattern and errors persist.

Pla, core one, max layer with 0.4 nozzle.

Any help appreciated

    Maybe a rebuild will fix whatever is causing this. Because when you experience:

    1. Stuck filament
    2. Underextrusion

    That does sound like a strictly a failure in the filament movement system. And I can only think of

    1. Grinding extruder, which can also be a symptom of the following
    2. Unstable temperature
    3. Clogged nozzle

    And since clearing the nozzle didn’t work, and you don’t find signs of grinding, nor observe temperature swings, then I’m out of ideas.

    Do you happen to have spare nozzles? Maybe try swapping the nozzle and see if it was still clogged? I’ve had nozzles that I just couldn’t clear.
