Print Quality Problem

Bambu Lab H2D
1

Hello, I have a problem with the print quality of the H2D, it is not so clear to see on the pictures, so I try to explain it,

  1. it does not matter which filament I use, for testing and comparison I used a standard profile, and as filament type Generic.
    Depending on the size of the object after 1 - 3 cm as between 0 and 1 inch the appearance and quality of the layers changes
    What could that be ?

Maybe because of different printing speeds…

might have something to do with it. But according to the profiles used, there is only a difference between the first and the remaining layers, but the problem lies at a height of approx. 1 - 3 cm
