Comment on One month ago, I didn't really know what 3D printing was. Yesterday, I designed in FreeCAD my first model and printed it. What an amazing experience.

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.
