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?
Without knowing what printer you have I offer this advice:
Does your printer keep the temperature? I had a creality cr6 that underextruded and in my case it was bad capacitors on the heating element circuit.
