Someone had turned the FabLab heater off, and when we had our cold snap, it got down to 50°F/10*C. All of the Prusa Printers are in Min Temp error right now, because the room is too cold to print.
I’ve turned the temp back up to 60°F, but it will likely take a while for the room to warm back up. The printers will not allow printing to occur until the room they are in is at least 60°F, as it causes issues with bed adhesion otherwise.
