Note: this is similar to [Drag Chain and X & Z control cables (too short?) (XL)](http://this post), but with (probably) a shorter wire.
My X stepper motor cable is really short. it has around 5" of wire outside of the drag chain at the controller box, and even less on the Spindle side (2.5" - the grey wire hardly comes out of the drag chain).
I will need a lot of spare cable properly mount the Y drag chain and run the wires from the back and to the bottom hole in the controller board. I checked, and the cable is running straight in the drag chains - no loops or extra wire.
