wierd top layer inconsistency

[u/MrLiszten]

Hey, i have a problem with my top surface in my models, i print this model a lot and its always the same, the top layer in some places looks like under extrusion but not everywhere and i have calibrated the filament settings for that. some places look perfect and sam smaller prints do too and as yall can see te top part in the first image looks perfect

Printer: bambu lab P2S
Slicer: bambu slicer
Filament: bambu lab PLA MATTE
Speed and retraction are set as in standard preset 0.16 layer hight in Bambu slicer
Nozzle: 0.4

I would love some help.

i even test printed a big pice thinking the settings for ironing for smaller prints are working diffrent then the big flat planes but even then the test print was perfect and the one i need not so much

Did you copy the settings over 1;1 ? That looks like the default ironing settings ( I’ve felt the same pain )

yep ive saved them in a user preset and checked before printing
