Spare ribbon cable??
-
I borrowed this pic from another user. Where can I get another ribbon cable like this one for the Duet 3 6HC?

Haven't seen them for sale as an individual item, if your vendor cannot sort you out I'd just order a generic 26 pin ribbon cable and two 40 pin idc contacts, cut he cable in half and press on the 40 pins connectors. (Or just all the individual parts. 1.27mm ribbon cable and 2.54mm idc for 26 and 40 pin ribbon)
Alternatively you can use 10 single 2.54mm dupont style wires and connect only the needed pins as shown on the wiring diagram, thats what I did the first time around, waiting for some parts so I can make a cable where I can continue with the cable past the raspberry pi to access the 5v supply, uart (and maybe i2c for a display)
