printing problem? or slicing?

hello printing fam

i got a strange problem when printing a large object on the pictures you see a line after the top solid infill

i already changed the vertical shells perimeters to 4

the red pictures from mk3s+

the black picture from mk2 

all sliced with prusaclicer

printed PLA

maybe someone knows a sulution?




when im printing a small part of the big part the result is better 


also some strange wave in the top solid infill 1 one corner

prusaslicer the wall is straight 


in this picture you see the problem

this black print got the same problem on my mk2 

prusaclicer makes a top solid infill to the outside wall


this was sliced with cura 

cura keeps the wall with infill, without a solid layer in between 

the result with cura is much better but i dont like the rest of the print quality with cura

I suspect this is a slicing problem.  Upload a 3MF File and we can check it for you:

RE: External perimeters

You could try it with enabling 'external perimeters first'. See
