Hello friends, I recently felt like trying out bigger nozzles, 0.8mm to be specific and I just cannot seem to fix my z seam which always ends up having a big gap, see pictures below.
People suggested elsewhere I should try to tune my pressure advance settings as well as extrusion multipliers, both of which did not fix the gap. I especially dont thing PA is my problem since all other corners print perfectly fine.
Attached is test_print.zip (renamed file extension from 3mf to zip), the file I’m trying to print because it highlights the gap pretty well
I do not have this issue on 0.4mm nozzles. They are the only other ones I’ve had on hand to test.
Alright, I’ve adjusted the setting in printer.cfg and it did not change anything. Settings were kept the same in PrusaSlicer because I had changed them accordingly before I even made this post. Attached are again the results, logs and relevant PrusaSlicer settings. klippy.log
Its somewhat better! I think using cura definitely contributed but it still seems like its not extruding far enough. One print had another hole in it but the second attempt was pretty alright. Compared to my 0.4mm prints the seam appears to bulge inwards a bit instead of outwards.
Ill crosspost this thread on the duet3d forum, looks like pretty much the same problem, thanks for the link
Nevermind as that thread appears to be multiple months old and necrobumping is generally not too appreciated
Oh fuck yeah, I’m so happy, I managed to fix it!
The setting “Extra Length on Restart” completely closes the gap! Its a bit finicky on faster speeds (25mm/s +) but at about 20mm/s its pretty close to perfect! Props to that one person on reddit who suggested it.
What a pain this was to debug. Thank you all for the help. I seriously appreciate it <3
