Filament build up on nozzle

Filament build up on nozzle

On some of longer builds, 2-3 hour into a print the nozzle has build up a little ball that drops onto te print and ruin everything 😑 

It seems like a little bit of filament every now and then and it builds up, but not always. Have printet 10 hours straight with no build up.

Is the nozzle too hot? Is it too close to the print? How does this happen? 🙂

Using Prusa Mini, 0.4mm nozzle (standard), 0.15mm layer height, Prusament PLA 1.75  (Jet black) and other PLA filaments
