I have been using my Smoothie board for months now and decided to swap out my hot end however I had it heated/power applied and forgot I had power applied and the live wires touched my extruder causing a quick short. I quickly secured power however to make matters worse I wired the new hot end backwards sending 12V off of the hot end power to the thermistor input and wired the thermistor to the 12V output. ow when I fire up the board all the axis work fine however I get a bed temperature of about 128C and an extruder reading of 526C. I basically cannot do anything at this point. Does anyone have any ideas or I have I smoked this board? I have two other thermistor input available however since the bed input has a reading issue now when I did not touch that portion I am very concerned. Maybe those input are protected by a diode or something that I can easily replace. Any assistance in resolving my stupidity would be greatly appreciated.
