Yeah seeing the original I suspected retraction settings since it was mostly in places with lots of retractions.and long paths even out and look smooth.
This fixed the under extrusion which seems to confirm it’s a retraction problem but disabling it entirely you’ve got those oozing artifacts where moves happen.
I’d suggest using a small value for your retraction and probably take the time to use teaching tech or ellis’ tunning guides to tune your retraction settings.
Yeah I’ve had foil bags with dessicant be damp too. In my experience, if you’re getting a deal on petg you probably need to dry it. That’s probably why you got the deal.
