I don’t have a prusa, but can you calibrate E steps on that printer? That can definitely result in a nice looking first layer and following less-filled layers if it’s off.
Thanks, everyone seems to agree on the under extrusion bit, so that definitely seems like what it is. I’m pulling my hair out trying to figure out exactly what. I may look at the e steps next. Ironing is not turned on, and I just cleaned the nozzle.

That is absolutely the next thing on my list to do. It still has the all plastic extruder, and my all metal replacement arrives tomorrow. I figured no point in calibrating until I replace that

Before you go through a bunch of calibration, I’d see if it happens with a different filament. Those black particles there are likely something with a higher melting point than the surrounding PLA, otherwise they’d “smear” during printing. I’m betting you’re hitting some intermittent clogs. See if the problem happens with a single color filament.

Thanks, i noticed this with my previous filament as well. This was a dual color PLA with under extrusion issues. I still have the original plastic extruder, and I bought it second hand, so no idea how much wear is on that arm. I ordered an aluminum upgraded one and a filament dryer, and they should be here tomorrow. I’ll upgrade the extruder, dry the filament, and check esteps afterwards to see if that was my part of the under extrusion.
