I have trouble fixing the terrible seams I'm getting. I've followed Elli's print tuning guide and calibrated extruder, tuned PA (it's now 0.035) and extrusion multiplier.
I've tried adjusting both retraction length and speed, but it doesn't seem to have much impact. I'm not using "wipe on retract" or "retract on layer change", I only retract if travel distance is longer than 3mm. Retract is 0.3mm @35mm/s.
I've tried reducing PA smooth time too, but this also doesn't seem to have a noticable impact.
I've tried reducing seam gap from the default 10% in Orca all the way down to 0%, but the bad seams persist.
I've tried with "wipe on loops" both disabled and enabled with no difference.
I've tried with both arachne and classic wall generator, no difference.
I've tried different wall orders, inner/outer, inner/outer/inner and outer/inner, all with the same bad seams.
Filament in the picture is matte PLA, it is without doubt dry and generally prints well aside from the seams. It's stored vacuum sealed with silica, and I use a filament dryer to dry if I suspect wet filament.
I'm running out of ideas for where to tweak to get a decent result.
Actually noticed my settings were not "default" at all because I had selected options in the calibration test section. I just started an actual default print with a top, bottom, multiple walls and infill hahah.
I'm printing with grid infill. Gonna cancel and try with gyroid.
I'm getting a 100% uniformly bad seam with grid infill, instead of the one in the pictures that kind of "switches side", which in guessing is because of the direction changes relative to the wall made for gyroid throughout the model, but grid always moves away from the wall at the same angle.
Edit: tried without any infill, same result as grid infill. So it's would seem it finishes the wall before it actually fully connects the wall-end to the wall-beginning on the outer walls, before changing to next layer or infill.
Yeah I got the same thing where it seems to pull when it's switching direction but it's nowhere near as bad as how it is on yours. I'm thinking it might be a physical issue with your printer.
Yeah you're probably right...I'll take a looks at the motion system then
Hopefully it's not too much of a pain in the ass, or at least leads to a fix. Good luck!
