Also more info about printer and settings. Are you using preassure advance or coasting? Temps, speed, retraction settings
Comment on What issue is this? Something with the z-seam?

Hard to tell, but obviously your printer is struggling on layer change and/or retraction. Assuming its not play in your mechanism, Id fitst try printing just that part of the model without retraction and see is the problem gone. If it is, maybe you have too high retraction distance that can cause partial clogs. If the problem persist maybe you are overextruding a bit and then nozzle drags that corner out of the position. Tiny overextrusion can be a pain when printing “walls only” models. Its more guessing than anything, it would be nice to see your calibration models

I think you might be on to something with retraction. The open cubes didn’t show it with the solid corner. I’ll be able to print another test print tomorrow once the second copy of this print is done. I’ll make a smaller cup tomorrow.
One question, when I manually feed the PETG into the 0.8 nozzle, the filament feels… Gummy? Springy? Not at all like when I’ve typically fed PLA into 0.4mm. I wonder if the springyness is leading to weird retraction

PLA is much harder and more brittle. Also PETG loves moisture and printers hate wet PETG, just saying
