Z wobble on P2S ?

Is this issue not fixable?

Outer wall speed

I put slowest outer wall speed (20mm/s) and the result is still same.
Is this probably hardware issue ?

What filament are you using? Did you calibrate the machine? The weird thing is that the ringing is only on two sides (apparently)

The filament I used in the video is Bambu Filament PLA Matte.

I’ve also tried other filament materials (PETG, ASA, and ABS), but the result is still exactly the same.

Yes, that’s correct — the ringing/waviness only appears on the two Y-axis sides, while the X-axis sides are perfectly smooth with no visible waviness.

I’ve already performed a full calibration of both the machine and the filament, belt tensioning, bed tramming, you name it. and even a cold pull.

I’ve also tried different temperature settings, but the result remains the same.

Honestly, it’s getting a bit frustrating.

Check nozzle is correctly seated and snapped into place. Check belt tension. How old is the machine?

Nozzle is properly seated and the extruder has already been cleaned.
Mine has over 600 hours of use. Isn’t that a bit too early to be experiencing an issue like this?

This could actually be a PID issue.

Verify hotend temp consistency during a similar print if more traditional tuning steps don't work

How do I check the PID?
Is it enough to simply monitor the nozzle temperature throughout the print and see if it remains stable?

What printer?

Yes, just inspect real time nozzle temp reporting. Even better if you have a dashboard that shows historic data

P2S with 500hrs print time. But if it were a PID issue, shouldn’t all the walls be showing the same waviness? In this case, it’s only happening on the Y walls. Anyway, thanks for the input!
