Themistor settings



  • I had to plug in a standard E3D Themistor onto my Duet2wifi
    and now im trying to setup the code for it.

    I have it plugged in E0 sensor on board

    This is my code but i cant get a reading so far

    ; Heaters
    M143 S280 ; Set maximum heater temperature to 280C
    M301 H0 S1.00 P10 I0.1 D200 T0.4 W180 B30 ; Use PID on bed heater (may require further tuning)
    M305 P0 T100000 B4138 C0 R4700 L0 H0 ; Set thermistor + ADC parameters for heater 0 - PT100
    M305 P1 T100000 B4725 C7.060000e-8 R4700 H1
    M143 H1 S280 ; set temperature limit for heater 1 to 280C

    would apprecaite some help, Im not great with decifering gcode

    That does look correct for an E3D thermistor, but I don't think you should be using H1.

    Hnnn If the sensor is a thermistor, this is the ADC high offset. If it is a current loop sensor, this is the temperature when the current is 20mA.
