That’s what mine did initially too. This is the adapter cable that worked for me.
Were you able to get your rotary working @Dreyfus?
No not yet but I think it’s a wiring issue as you say. I perhaps just need to get the order right.
This is the motor end of the cable I’m using -

Ah, changed the wiring to straight through -
Red
Blue
Green
Black
and the rotary test on lightburn is working. Cool
Now I need to learn how it works 
That YAML I posted for A# is the one I used with no other changes, for anyone looking at this in the future.

Glad you got it working, but I feel the need to post a heads-up for others looking for motor wiring fixes. Be careful assuming the colors from one motor will be the same as another, even from the same supplier. What’s important is identifying which are windings. There’s also no guarantee that the colors on any extension will match up with the motor wire colors.
To identify the winding wires, start with the motor disconnected from the controller. (Power down the controller before plugging or unplugging motors to prevent damage to the motor drivers). Next, turn the motor shaft by hand to get a feel for how smoothly and easily it turns. Now short any 2 wires together and turn the shaft again. If there is no change, those leads are on different windings. If there is resistance and the motor feels “bumpy” then those two leads make up one of the windings. On a 4-wire stepper then the other 2 wires should be the other winding - short them (and disconnect the first winding) to confirm.
