3d printer babbling
So, what has actually happened here is the nozzle and the throat elements have separated under heat, allowing pressurized Pinkamena - er, pink PLA filament at 220°C - to ooze out and coat the heating element atop and bottom, caramelizing slightly.
No biggie. Going to clean it off, then retighten with the block *at* temperature, allow to cool, then reassemble. Should solve that problem, and possibly address a minor print issue I noticed.
