On the bottom of my prints, there's an area of underextrusion and I can't figure out what's causing it.
I first noticed it when I switched back to a textured PEI bed while trying to print ASA. It's on 20x20mm squares, and it's on the test print for setting up pressure advance... But only on the left-most object.
It's the same even if I add 2 lines of skirt or not. (In addition to my KAMP Voron purge.)
It happens everywhere on the bed that I've tested. It happens to PLA, but it harder to see. For ASA, it's very obvious. For PLA, it's almost as smooth as the rest of the surface, but it's there if you know what you're looking for.
I've only been printing PLA for quite a while now, so I don't know when this started.
I've got an LDO Voron 2.4 with Tap, KAMP, Revo hot end. I've calibrated pressure advanced and changed the value, and I've tried different z offsets with the textured bed, which doesn't change it. (But does change how good the rest of the bottom surface looks.)
Anyone got any ideas?

Yeah. I recognize the bias and the need for clicks/eyeballs, and their motivations, and it applies to all of them. I generally expect someone telling me something to not be deceiving me, and I'm so often disappointed.
