4 conductor cable for the Panel Due
-
I bit of nitpicking.
I use my Panel Due in a movable case. It came with a horrible cable, 4 loose cables attached each end. They get stuck on everything all the time.
It would be a lot nicer with one 4 conductor cable instead of 4 one conductor cables.
I could make my own cable...
Or pull a cable sock over it... -
I also use a moveable case and am using a 4 core UL2464 cable. You can find them on Aliexpress and many other places.

Just add some heatshrink to keep them together

@bondus Remove one of the connectors and twist the wires together or get some spiral wire wrap, like https://www.amazon.com/Uxcell-a13032800ux0333-Clear-Polyethylene-Spiral/dp/B00CW8V7X2/

I use braiding for this with a short piece of heat shrink at each end to hold it in place, I also only ever use flexible silicon covered wire in those situations where flex is involved.

I use this cable to connect a PanelDue if I am not using the ribbon cable: https://uk.rs-online.com/web/p/multicore-industrial-cable/6604037/. It's resistance is 0.092 ohms/m so according to our recommendation of not more than 0.1ohms per conductor, it's good for cable lengths up to about 1.1m. On my delta the cable is somewhat longer than that, but the 7" PanelDue works.
Polyester braiding on the existing cable with heatshrink at the ends as @Dougal1957 suggests is also a good solution.

@stephen6309 I can't see why you would need to remove a connector to twist the wires. I just put one end in a vice and twisted the other.
-
@nophead Twist one pair, then twist the other pair, it won't untwist as easy as doing all at once.
-
Actually, I think the opposite is true. The pairs in themselves will stay twisted but then the twisted pairs won't twist well together.

Best IMO is to remove the pins from the connector shell at one end (easy with the Molex KK connectors); then hand-twist the 4 wires around each other without imparting a twist to the individual wires; then re-insert them in the shell. If you twist the cable with the shells in place, then the individual wires have to twist, and then they will tend to un-twist the cable.
For stepper motor cables, I prefer to twist the two wire in each phase around each other; then loosely twist the two pairs around each other. This minimises magnetically induced EMI.
