I plugged in my printer for the first time and after about twenty seconds the mosfet on the heated board begun smoking. The signal light was on while this was happening (the one on the heated board) and the board also got hot. I have wired everything correctly according to the wiring diagram I was provided with my printer and was wondering what I had done wrong or if I was given the wrong instructions as my board is slightly diffrent. Here are some pictures... [imgur.com]
