Any Way To Avoid PETG "Crumbs"?
I've recently run several versions of a design in Prusament PETG on my Mk3S+ using the default Prusament PETG settings in Slicer. The prints work (I've had one failure out of 8 so far) but seem to always contain little wads of plastic on the trailing edges (mostly) of various surfaces. Most of these break away cleanly in post, but a few are embedded and require quite a bit of effort to remove. Does anyone have suggestions either for the design or the printer configuration that can help eliminate these?
The print pictured was printed from a new spool of Prusament PEGT Anthracite Gray taken directly from the vacuum-sealed bag with the desiccant, so there shouldn't be excessive moisture. (It's also winter here and ambient moisture is fairly low.)
Any suggestions would be greatly appreciated.

I would definitely dry the filament. The stringing and "crumbs" are typical of moist PETG. Just because it was in a bag doesn't mean anything. Could have been sitting in a warehouse for months. And if Anthracite Gray is anything like Neon Green, which I love to cite as the worst example, it may need overnight drying and still crap out by the end of a day of printing.

Thanks! I tossed the spool in the dryer overnight and it is performing much better now. Strange how much impact a minuscule amount of moisture can have.
