I had a hard time figuring out how to manage the cables on the X axis. Y was the easiest, I used some igus cable carrier that was to be thrown away. Z was easy as well, I used some KabelSchlepp carrier. This worked even with out fixing the carrier to anything. The range of motion video shows these two working. The X axis has the largest bundle, power for 4 steppers and the spindle. There was no easy way to mount this bundle on my wall mount frame. I finally abandoned the carrier I had bought and built this.
I used:
1-8ft piece of 1.125 OD dowel
2in OD ABS pipe cut into 13 2in wide rings
10- IKEA Hooks
4 Zip Ties
3/4 Plywood mounting brackets.
I will post further details on how I made this in the Projects page.
