Help wanted undextrusion and stuck filament (thelemmy.club)

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

If temp is stable try having a look at the filament. Is the extruder grinding the filament?

It could also be a case of a blocked nozzle. Though that doesn't explain the stuck filament. scratch that I just reread your post

When starting with an unpowered printer, i.e. the first print after powering printer up, does the issue happen at any part of the print, or only after a little while?

    Picture works now. It starts immediately

    And no grinding on the filament.

    Edit thr indx upgrade is coming soon so a thorough rebuild is coming too.

    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.
