What can fix this problem?

I print with a bambulab p1s. Filament is Eryone PLA grey matte, everithing is calibrated two times and came out well. I dont have this problem with the same Filament in withe matte. when you look on pictures, anyone have any advice or suggestion what i can do to fix this problem? it is just on the sides, not bottom and very little on surface. thanks alot if anyone could give me his expertise
settings:

  • 220degree celsius
  • 0.4 nozzle
  • layerhigh: 0.1mm
  • arachne
  • infill: trihexagon 6 % / kombination infill selected
  • inner wall first
  • speed: outer wall 200mm/s, inner wall 300mm/s, infill 430mm/s
  • overhang lower than recommended
  • acceleration 10000mm/s2
  • slicing regular
    other settings standard



If it prints ok with one color, brand, and type of filament but not another color though same brand and type, first place I go is if your filament is dry. But I haven’t had that kind of defect to know.

But other than that, you don’t give any information about your other settings which others may want to know before they can help you, or maybe someone will know right off.

Did you try a temp tower? I have also been trying to calibrate ABS with a 0.2 nozzle … the calibration flow etc look beautiful, but as soon as I tried the benchy and then the tower the quality is terrible with blobs and strings.

This looks like an huge and very detailed print. Have you checked gcode that it sliced it right. Maybe just try these areas by themselves as test prints to see if they look right.
