After a short hiatus in usage of my printer, my bed does not heat.
Stats:
My extruder heats up normally. When I set a temperature for my bed, it begins heating but around 70C, the MOSFET LED goes out and the temperature plummets. If I disconnect the one or both of the bed wires, LED will come back on until I reconnect the wires. The only way to reset it seems to be to unplug USB and turn off the PSU.
My bed has a resistance of about 1.1 ohms, which seems within normal limits (although confirmation would be great). Any help or ideas will be greatly appreciated.
