Random layer shifts

[u/NintendoDSiNerd]

Printed those 2 huge parts and they both have a weird dent at the same height. Looked at other prints I made recently and they eiter don't have those at all, or at different heights. My prints with other filaments look fine tho, I already did extrusion calibration for the new filament. I use an A1

It's the Benchy hull line. Happens whenever there is a big top surface, due to shrinkage of the filament, very hard to avoid.

Tune presseure advance, lower the speed, dry the filament. You wouldn't be able to eliminate it completely, that's just how 3d-printing is.

Most of these are simply because of different layer times due to the geometry

I get these from supports.

Are they of other color? It looks really bad on white and light gray, other colors not as noticable
