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



  • its a duet wifi sorry and my config looks like this for the heaters
    ; Heaters
    M143 S260 ; Set maximum heater temperature to 260C
    M305 P0 T10000 B3988 C0 R4700 ; Set thermistor + ADC parameters for heater 0
    M305 P1 T100000 B4138 C0 R4700 ; Set thermistor + ADC parameters for heater 1

    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.



  • yhatzee!!! lol fixed it and sir again you are amazing thanks for putting up with all my questions its truly appreciated
