I have this problem when printing with 0.8 nozzles with PLA on a 0.4mm layer height. when setting 'z-seam alignment' to 'user specified' (see attached screenshot) i get this poor quality, seems like the PLA is coming in too late. never had this before but since a few weeks nothing helps to make it better. so question is: what settings do I need to change?
cheers, Leon
