I also posted this information in the Z band thread, but since that thread is so long, it might get overlooked so I wanted to share it here as well.
The filament I used for testing was eSun Pro PLA black @ 215c FYI.
Bambu filament fan settings you can see lines and also feel the big middle line with your fingernail. I was trying to capture the photo to highlight the big lip.
I adjusted the fan settings on this test part to eliminate the big 0.2 mm wall band that appeared in the middle. The wall thickness was scaled down from 10 mm to 4.40 mm and then to 2 mm, which caused the plastic to cool at different rates the infill was 15% rectillinear so the wall looks smooth and great now.
The lower fan settings I used in this test aren’t a universal solution for PLA or other prints, but they offer alternative cooling strategies that are worth exploring when working with PLA filament and various part designs.
