Is this a dirty nozzle

Yes, I mean the two holes. There is one on the other side as well. I can't tell if they just appear as the filament stretches as I remove it, or maybe there is something in the nozzle. But I would expect if there was something in the nozzle, the holes would look like lines as I pulled the filament out over the obstruction. Or maybe it's voids in the filament? It is MatterHackers Pro Series PLA which I think is pretty good stuff. The outer surface of the filament is perfect.

    Ditto; never seen it and yes a scrape rather than a hole is more logical. We probably need a materials expert to answer this one.

    I get similar various holes in my filament when doing atomic. Otherwise my nozzle seems fine and everything works.
