Hi,

I accidently did a short circuit on the heat element on the hotend. Now I got minus degrees on both heat sensors.
Is the board broken or only the sensors?

    If you have not unplugged anything then it is very likely that this is a broken board :disappointed:

    If it was only one port broken, you could use the spare port, but if there are two broken ports, you probably need a new motherboard.

    Okay, I connected a new thermistor for e0 and it Shows the right connection. Maybe only the thermistors were burned.it is possible to Change the bed thermistor? I never took care about it

    You could attach a new cable thermistor to the bed using kapton tape. I would use a multimeter to check the resistance of the bed thermistor, it might be ok.

    The thermistor is good, I was able to use the free Therm 1 pin for the bed and it is working again. :)
