      Just finished modifying my printer to run on a Duet Ethernet and through Repetier host the second extruder only reads 100C all the time. The bed and Extruder 1 work fine. How do I fix my printer to read the proper extruder 2 values?
      Extruder 1 is a genuine E3D V6
      Extruder 2 is a Velleman K8400 extruder.
      Using https://configurator.reprapfirmware.org/ I get these values for the Temperature setup portion of config.g

      M305 P0 T100000 B3950 R4700 H0 L0 ; Put your own H and/or L values here to set the bed thermistor ADC correction
      M305 P1 T100000 B4388 R4700 H0 L0 ; Put your own H and/or L values here to set the first nozzle thermistor ADC correction
      M305 P2 T100000 B2743 R4700 H0 L0 ; Put your own H and/or L values here to set the second nozzle thermistor ADC correction
      M143 H0 S250 ; Un-comment this to set maximum extruder temperature, default is 262C
      ;M141 H3 ; Un-comment this to set chamber heater/thermistor channel

      M570 S180 ; Hot end may be a little slow to heat up so allow it 180 seconds

      ; Tool definitions
      M563 P0 D0 H1 ; Define tool 0
      G10 P0 S0 R0 X-33 Y0 ; Set tool 0 operating and standby temperatures
      M563 P1 D1 H2 F2 ; Define tool 1
      G10 P1 S0 R0 X33 Y0 ; Set tool 1 operating and standby temperatures
      M92 E150:150 ; Set extruder steps per mm

        The B value of 2743 in the M305 P2 line looks rather low. Where did you get that value from? However, a wrong value there wouldn't cause it to read 100C all the time.

        Does heater 2 also read 100C in the web interface?

          I got the value from the reprap configurator calculator and measuring the thermistor resistance at different temperatures. I dont have the network side of my setup finished yet so i dont have access to the web interface however in Pronterface Ext2 reads a constant 0C.
