Sbc wiring problem

[JuL]

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

OK, not what I expected.So, is it possible to
wake up pi with pson pin?

[jay_s_uk]

@JuL what do you mean wake it up?

[JuL]

I mean I don't want to unplug and plug my pi each start

[jay_s_uk]

@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
