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.
