Ok, I noticed banding/ringing in some simple prints (cylinders with wall thickness >1mm) in white bambu basic PLA and decided to do some tests.
The print is 2mm wall thickness with 0.2mm standard settings. I only played with the temperatures.
(Right 220°, left 205°)
Interestingly, it does not have any impact on the bambu basic grey. I guess it is due the pigments and/or different manufacturer.
