PLA doesn’t like heated enclosures, basically the filament melts at such a low temperature that the heat inside the printer can soften it enough to jam up.

If the printer is fully enclosed (door and lid closed) and the print is long enough. The heat from the hotend and bed can build up in the chamber, causing heat creep. The chamber temperature is not monitored. Since the nozzle and heatbreak are one piece, removing the clog is a bit more involved.

I’ve had to do it 3 times since I bought the printer on release. All were 12+ hour PLA prints and done after high temperature filament prints (nylon and abs).

The issue is entirely preventable, just me forgetting to open the door on long prints lol.
