      I have a Board: Duet 3 MB6HC (MB6HC) running
      Firmware: RepRapFirmware for Duet 3 MB6HC 3.2-beta2 (2020-10-05b2) with the latest beta firmware on my Toolboard:
      Board TOOL1LC firmware 3.2beta (2020-09-14b1)

      Occasionally I hear and see my extruder heater fan start for a few ms (less then a second)
      I checked cabling and I've got no spikes in my temperature readings.

      Everything runs fine while printing but I though I should report it.

        @jbarros said in Toolboard: Heater fan goes of for a few ms with printer idle:

        M950 F2 C"20.out2+out2.tach" Q500 ; create fan 2 on pin 1.out1 and set its frequency M106 P2 S1.0 H1 T45 L1.0 ; set fan 2 value. Thermostatic control is turned on;

        Is it the same fan that has the tachometer?
