Once I had it everything set up to start printing and calibrating, the printer the power supply would randomly turn off. I would have to unplug the power supply from the wall to reset it then it would be fine. It has progressed to the point that anytime I try to use the heated printer bed the power instantly shuts off before it has a chance to do anything.<br>
