      Hi, I'm trying to wire à duet3 6hc rev 1.02 with à pi4. What I did:
      -removed sd card from duet
      -Wired 24vdc psu to duet power in
      -wired 5vdc psu to duet ext 5v (+5 and gnd, no pson)
      -put a 2 way jumper between ext 5v and ext 5v sel
      -User original 26 to 40 pin ribbon from duet
      When Turn on, duet seem's to start correctly ( 4 led on + statues led blinking) but no power to pi (I tried pi 3 and pi 4, no led activity at all)
      What am I missing?

        @JuL you can't power the pi from the 6hc any more. You need to provide power to it separately

                @JuL then get a 5v power supply to add to your printer to power it

                  I already have à 5v psu just for that. Was hoping not to have to do my own ribbon cable(I don't want to use the usb c power port on pi). Thx for the help

                    @JuL you can still use the 5Vin on thr Pi GPIO header, but be aware that bypasses overvoltage protection.

                      I inverted gpio pins 2, 4 and 6 under the pi board (so no more in the ribbon cable) and solder 5v directly on it. Works like I wanted. Thx
