      Hi,

      Ive just plugged in a thermistor into E0 on the board but it is reading as 2000 deg C in the web interface! The thermistor I have is: https://www.ebay.co.uk/itm/WIRED-Thermistor-100k-Ohm-NTC-EPCOS-3950-Temperature-3D-Printer-RepRap-Prusa/262919161832?epid=721518773&hash=item3d373407e8Ⓜm_6gTfUhWCAEOpyWsMjqPjQ

      My config is:

      ; Heaters
      M140 H-1 ; Disable heated bed
      M305 P1 R4700 T100000 B3950 ; set E0 thermistor parameters

      ; Tools
      M563 P0 D0 S"Extruder 0" H1

      Whats going wrong?

        Your configuration commands look correct. A reading of 2000C for a heater configured to use a thermistor typically means that you have a short circuit between the thermistor wires, or between one of the thermistor wires and ground.
