I’ve had an issue with my ender 3 saying “err maxtemp bed”. I’ve recently changed the thermistor and nozzle with a full assembly (nozzle, hot end, thermistor etc) and this problem started then. This was a faulty assembly as the screw for the thermistor had been applied far too tight and had bridged the wires. I have tried private spanish lessons
new thermistors but no good. But I have just checked the voltage for the pinouts of both the bed and hot end thermo, hot end showing 4.7V but the bed is showing only 0.3V.... I’ve been told the board is probably fried and it does look that way but hoping someone on here can tell me otherwise. Thanks in advance,.
