Help wanted undextrusion and stuck filament
(lemmy.nz)
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?
How about your filament path? Is there high resistance? The filament roll, is it hard to roll on your filament holder? How about reverse bowdens?
Is the extruder gear too tight or too loose?
I found that new rolls seem to not want to unroll as easy because of the weight. If I have this problem, it's usually on a new roll.
A low friction filament path solves a lot of under extrusion issues. See if you can build a filament holder with ball bearings and/or a filament guide before the extruder. It solved all my issues with my former Ender 3.
