I have my prints with marks on the sides, for example: a box has a mark on all sides. These marks do not appear on the Bambu Lab slicer. Does anyone have any idea what could be going on?
A picture of the issue and uploading the .3mf file would be really helpful.
The lines could be a layer shift, unfortunately it is common. Usually caused by a bump on the print head knocking off its position very slightly but, obvious on final prints.
The one with the gouge looks more like filament flow was interrupted by something stopping it getting into the print head. Sometimes the filament gets stuck down the side of the spool edge and the printer can’t free it, yet, not sufficient to stop things, so the printer keeps going. After a period it becomes free and everything above it is fine.
These are guesses, without being there, that is all I can provide.
