P2S Persistent Z-Banding / Z-Wobble

Hi everyone,

I’m looking for some help diagnosing a persistent Z-banding / Z-wobble-like surface artifact on my Bambu Lab P2S. I have been troubleshooting this issue quite extensively, but so far I still haven’t been able to eliminate it.

The printed surface has a very consistent repeating wavy pattern along the Z direction. It is particularly noticeable on the Y-facing wall, while it becomes less visible toward the X-facing wall. I am currently printing in Vase Mode, so the artifact is easier to see because there is only an outer wall. If anyone has suggestions for specific tests I can perform, I would really appreciate them.

Thanks in advance!
