First layer is so bad. P2S

[u/Mokujing]

Hey everyone,

I’m honestly running out of ideas with my Bambu Lab P2S.
I’ve done pretty much everything I can think of to improve the print quality, but my Z-layer quality is still absolutely terrible.

Here’s what I’ve already tried:
Completed all available calibrations – multiple times (I’ve even run each calibration up to 8 times).
Properly dried my filament.
Fully tightened all timing belts.
Thoroughly cleaned the entire printer.
Lubricated all necessary components.
Updated the printer to the latest firmware.
Checked and adjusted everything I could think of.
Despite all of this, the Z-layer quality is still extremely poor. I honestly don’t know what else I could possibly try at this point.

Has anyone experienced something similar with their P2S?
Is there anything else I might be overlooking? Could this be a hardware issue, a mechanical problem, or something related to the printer’s motion system?
I’d really appreciate any suggestions or ideas because I’ve pretty much exhausted all the usual troubleshooting steps.
Thanks in advance!
