Z-Suite slicing problem

Hello everyone, I have a problem with setting up my print. This is showing when slicing.
Seam is not random, but when I want to have random tiny little dots on all print show instead of this line.

Hi,

Actually, seam will always be visible on the print. It is the starting point of each new layer, which appears as a slightly visible mark on the surface of models. It can be either normal (the same point on each layer, as shown in the picture you attached) or random (different point on each layer, random little spots on the print).

Best regards,
Karolina

Is there a setting that can make it less visible.

No, sadly, such a setting is not available.
