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
Edit is the image not loading for everyone?
Since I have the end of the pulled filament and can see the 3 times split from the cht the blob is either not there OE inside one or more of the smaller channels after the split.
