Possible Z Wobble? Inconsistent Layers

Printing brand new RR PETG at 255°C on 3.1 500
Acceleration: 6k mm² /s
Perimeter Speed: 175mm/s
Hotend: Rapido UHF
Nozzle: CHT Volcano 0.4mm
Extruder: LGX lite
EM: 0.95
E Steps are spot on (last I checked 2 months ago)
Layer Height: 0.2mm
3 perimeters

Here are some photos. Looks consistent across all the layers.. which makes me believe it’s something to do with my Z axis.. but not quite sure what to check first.

I took a photo of a calibration cube I printed immediately before this print. Which looks pretty good minus a little over extrusion on the top layer.
