I have a MK2S printer and the bed is not heating. I noticed the led light does not turn on. Cables all look good, sodering joints are fine, the fuses are ok, hairdryer trips the temp sensor and shows the bed getting warmer but I don't see any voltage on the gnd/VCC line on the bed when I measure it. Does this mean I need a new PCB Robo Card? The error on the screen shows - Preheat Error. I've upgraded to the latest firmware as well.
