      Hello i have just installed a second hotend and the thermistor is about 80c off

      This is how i looks in the config
      ; Thermistors
      M305 P0 T100000 B4388 R4700 H30 L0 ; Put your own H and/or L values here to set the bed thermistor ADC correction
      M305 P1 T100000 B3950 R4700 H30 L0 ; Put your own H and/or L values here to set the first nozzle thermistor ADC correction
      M305 P2 T100000 B3950 R4700 H30 L0 ; Put your own H and/or L values here to set the second nozzle thermistor ADC correction
      M570 S180 ; Hot end may be a little slow to heat up so allow it 180 seconds
