      I can't set the chamber temp via Gcode terminal?

      This is in my config.g:

      ;CHAMBER heater dual thermistor setup
      M308 S9 P"duex.e2temp" Y"thermistor" T100000 B4725 A"Chamber HEATER" ; configure sensor 9 as thermistor on pin temp1 (CHAMBER HEATER)  C7.060000e-8
      M308 S7 P"spi.cs6" Y"dht22" A"Chamber Temp"          ; define DHT22 CHAMBER ACTUAL temperature sensor (CHAMBER TEMP)
      M308 S8 P"S7.1" Y"dhthumidity" A"Chamber Hum[%]"        ; Attach DHT22 humidity sensor to secondary output of temperature sensor
      M950 H2 C"duex.e3heat" T7 Q60                                   ; create bed heater output on duex e3heat and map it to sensor 7 (CHAMBER TEMP). Set PWM frequency to 60Hz
      M141 P2 H2                                                  ; Mark heater H2 as CHAMBER heater (for DWC)
      M143 H2 P1 T9 A2 S100 C0                                    ; Regulate (A2) CHAMBER HEATER (H2) to keep thermister (T9) below 200°C. Use Heater monitor 1 for it
      M143 H2 P2 T9 A1 S200 C0                                    ; Shut off (A1) bed heater (H2) if pad sensor (T9) exceeds 120°C. Use Heater monitor 2 for it
      M143 H2 S70                                                ; Set chamber heat max temperature to 56°C, use monitor 2 which is configured
      M307 H2 S1.00              ; disable bang-bang mode for the bed heater and set PWM limit B0 R0.168 C1269.4 D15.79 S1.00 V24.0  
      

      entering M141 S30
      Returns:

      M141 S30
      Error: M141: No chamber heater has been configured for slot 0

      What!?

        Never mind I see it:
        M141 P2 H2 should be M141 P0 H2
