      Good morning everyone,

      I’m trying to set up two thermostatic fans to ventilate the MCU and electronics, based on the MCU temperature, using the following code:

      M308 S10 Y"mcu-temp" A"MCU"                                   ; Set or report sensor parameters  
      M950 F13 Q500 C"1.out4"                                       ; Configure MCU fan  
      M950 F14 Q500 C"1.out5"                                       ; Configure MCU fan  
      M106 P13 S1 T25:70 C"MCU Fan" H10                             ; Set fan configuration  
      M106 P14 S1 T25:70 C"MCU Fan" H10                             ; Set fan configuration
      

      The issue I’m facing is that I don’t have any available outputs on the Duet 6HC, so I have no choice but to use the last two outputs on the Duet 3HC. I understand that the problem is that since I’m monitoring the MCU temperature of the Duet 6HC, I should be using outputs from the 6HC and not the 3HC.

      So, my question is: how can I monitor the temperature of the 3HC instead of the 6HC? I’ve tried M308 S10 Y"1.mcu-temp" A"MCU", but, as expected, it didn’t work.

      Best regards,

        @Aitor add parameter P"1.dummy" to your M308 command. This will cause the M308 command to be routed to board 1. [Edited]
