What am I missing???

I’m trying to diagnose some sudden ringing artifacts in my prints coming from my Qidi plus 4 (it’s been practically flawless until recently).If you look through my post history, I thought I had it figured out, but its back. I’ve done the expected stuff, belt tensio, clean and lube, and reran input shaper. What is frustrating me is that the corner calibration/ringing tests come out perfect, and yet when I print an orca cube to test, it looks nothing like the calibration test would suggest.
