      Hi there,

      first of all thanks for this awsome piece of hardware !
      And please excuse my bad english 🙂

      I recently set up everything and got it running after a few tweaks.
      But im running into a problem, not being able to control the fan 0 port

      Others work just fine… M106 P* S1 (Same Fan used for testing on all ports)
      When i measure those i get stable 24v from other ports but on port 0 only 3.2 -3.5

      because i need some prints to switch to my new printer i tryed to remap P2 to the extruder/tool 0
      M563 P0 D0 H1 F2 ; Define tool 0

      but i doesnt work (even when tool is active)
      Manual M106 P2 S1 works...

      I double checked if fan is in temp control mode or inverted but its not.
      FAN Conf:
      M106 P0 S0 ; (supposed to be Partcooler)
      M106 P1 T45 H1 ; (Hotendcooler)
      M106 P2 S0 ; ( spare part cooler - but cant get it running with remap)

      may my board be broken ?
      im thankfull for any advice or help

      greetings from germany

      Benny

        No quite sure I understand the problem. The S parameter determines to PWM fequency, so S0 will effectively turn it off. S255 will turn it on at full speed. https://duet3d.com/wiki/G-code#M106:_Fan_On.

          you can send like M106 S0.5 which is 50% PWM 0.6 = 60% and so on
          but i tried 255 with the same results

          Problem is that i cant get port 0 working like the other two (with same commands) -switching it of S0 gives 0 volt
          ON gives 3.x volt

            Ahh I see. Is the 3 volts with the fan connected or disconnected?

              disconnected

              is there any kind of support ticket i can open for this - im about 80% sure the board is faulty

                Im a little disappointed not getting any "official" support here…
                Website says better use forum instead of writing mail - dont want to return the board - prints really good - but allways turning the fan on per hand sucks

                i'll try mail tomorrow 😞

                  It does sound as though the Fan0 output is faulty. In such cases you need to email the supplier that you purchased the board from, to arrange a replacement.
