@Danal said in Duet3 6Hc + Duex 3Hc with Raspberry 3B+ Wiring Check:
I can't see the jumpers for you Pi power, there is a yellow cable crossing in front of them. Double check them per the wiring diagram.
INT 5 EN and 5V TO SBC are bridged so that the SBC gets the power from the Duet.
Thanks, so i will plug it in and make a Duet Pi upgrade via sudo apt-get update / upgrade from its Screen, Keyboard and Mouse which are plugged in.
