      My bed temp sensor is reading a negative 273 degree reading and gives me an error in the web interface I tried plugging in the hot end temp sensor ( which reads correct) into the bed sensor location and it still reads negative any help would be appreciated

        What type of Duet is it, and what M305 P0 command (if any) do you have in your config.g file?

            Your bed heater thermistor is set up for a 10K bed thermistor (T10000) but you probably have a 100K thermistor. Try T100000 in the M305 P1 command.
