Regularly spaced lines on pieces (Z banding?)

Setup: VCore 3.1 300, LGX Lite, Rapido, Orca Slicer, RatOS v 2.0.1 These prints were made with Polymaker CosPLA at 200C Hi everyone, I'm currently experimenting a bit after noticing my prints have this really annoying uneven surface, showing these equally spaced lines (that seem to have 4mm spacing, so it should be Z wobble?) It seems like setting the wall order as inner/outer/inner mitigates the issue, but it doesn't solve it at all (all photos are from pieces made with the standard inner/outer order just saying) I already checked my Z rods and they are straight, PA and IS are calibrated, PID tuning of bed and extruder was made. What else should I look for, given that it's probably Z axis related?
