Replace MOSFET Switch on 3D Printer - MonoPrice Select Mini by Dave Wirth
PlayList of all my 3D Printing Video's: https://goo.gl/FKD0Tq How i replaced the MOSFET switch on my Monoprice Select Mini 3D printer. I burned out something on my 3D printer when i accidentally shorted out the heater break. I wrapped it with aluminum foil as a heat barrier and the foil touched both the + and - wires on accident. Smoke came out of the circuit board and the hotend would not heat up. I was able to diagnose the problem when i switched the heated bed wires with the hotend wires and then the heated bed would not heat up. I narrowed the problem down to the MOSFET switch on the circuit board. The MOSFET is and On / Off switch that is controlled when power is added to it. It was burned out and was permanently Off. So i bought a new switch and soldered it into place. Luckily it worked. I realize that this is something that would only happen in rare circumstances but hopefully it helps someone. I also could have bought a new circuit board for the monoprice select mini for $60.
