Mini 5+ and SBC Power
-
Hi...
soon i get my Duet3 Mini 5+ and i have a Pi3b+ in my setup. For now i power the pi with a stepdown to the GPIO Pins. When i connect the Duet Ribbon the pins are hidden... The Duet can not power the pi.
Are the first 2 Lines in the ribbon cable for 5v and ground? So i could cut the two lines on the Duet side and put them in the Stepdown? Anybody did that already? I don't want to power via USB Connector (optic ;)).
Or could i leave the Ribbon Cable as is and solder cables for + and - on the bottom of the gpio Connectors on the pi?

I made my own cable up from Duet3 Mini to Pi, due to it covering the GPIO power input pins.
Short piece of CAT6 and some DuPont connectors, job done.
For power, I used a slightly heavier gauge cable. -
@paulhew Interesting, can you share a picture?

@toddel https://duet3d.dozuki.com/Wiki/Duet_3_Mainboard_6HC_Wiring_Diagram and in particular https://d17kynu4zpq5hy.cloudfront.net/igi/duet3d/33DEuEJZXP16vLbF.huge
You need most of pins 17 to 24 . You don't need all the 0V lines that lists, just one of them.

Forgot to add, the 2 DuPont's with no cables were to help me locate the new plug due to the boards being on the side of the printer and counting at an angle is hard, for me!
