My 3d printer appears to have taken up a drinking habit

[GeoffMAOT]

Hi all, I have a Ender 3 Pro.

I've put several spools of filament through it with no issues. Lately, it's been having some issues.

I printed a wheel, and it was probably 80% done before it seemed to forget what it was doing. Bottom half, perfect. Top half, slanted like a drunken sailor.
I then printed a large print that was also circular. It printed the first 2mm, then shifted somewhat and printed the rest of the model (4+ inches) 2 mm to the right.
After that I noticed quite a bit of buildup around the nozzle, and above the nozzle (around the heatsink). Took it all apart and cleaned it.
Started another print of the wheel, and this time the print was even worse.

Images are attached.
First iteration named 1st pt1 and pt2. Second named 2nd pt1 and pt2.

Both are the same model. Same filament (Overture PETG). Bed 84C. Nozzle 240C. Platform: Raft

First iteration:
layer height .2
Shell 1.2
Infill 40%

Second iteration:
layer height .06
Shell .8
Infill 40%
