I’ve noticed this happening a few times seemingly randomly and I cannot explain it. I’m using just the default monotonic bottom surface pattern.
These lines are on the solid infill for the bottom layers, and watching the printer, what is happening is that it’s overlapping itself by exactly one line when it is doing the infill on parts where it cannot do a single continuous fill across the layer.
In the slicer itself I see no evidence of this instruction, yet watching the printer that is exactly what it is doing.
Has anyone else seen this before?
Is it related on this .3mf specifically or do you get these on any print?
I have a similar problem on all prints. It’s either weird slicer logic or the printer. My Prusa MK4 from Prusa Slicer prints the same models without this defect.
The worst part about this problem is that these overlaps are not covered even by the last printing layer and they are visible on the surface. It looks like it was printed on a cheap Chinese printer.
This problem in Bambu Studio seems to be caused by the Rectilinear infill in the Internal solid infill pattern parameter. Change it to Monotonic or Monotonic line.
