I'm struggling to solve this Z banding. This test was with PLA @ .3mm height. Happens with or without infill or Arachne.
#Consistent 2mm Z banding. 3.1

I do see some wobble in my back lead screw...
Man, I'd sell this printer in a heartbeat if I could get it through the door

I had similar banding on a different CoreXY when the Z rails weren’t all parallel. In my case there was both a squealing noise and the un-captive lead screws would wobble at the top if I sent the bed from the top to the bottom Z height.
To be more precise, one rail wasn’t parallel to its lead screw which caused binding and imperfect Z movements, but it wasn’t visually obvious when looking at the printer.

How did you discover this?

See the message above that about the noise. I zeroed Z and then moved to max Z and there was an apparent sound and wobble at the very top of the lead screw as the bed approached the bottom of the printer.
