Are your cords coming in from the opposite side from where your control box is located? If so, I think you will face issues on that. This is not so much related to my remix designs or even drag chain in general. It would also be the case for vac hose too.
The more I look at it, the more I am thinking that cords from the right with control box on left, is a no go. See illustration below, in which the cable chain is mocked up in blue, and control box is duplicated to be shown in both possible side positions. Notice how as the core moves toward home (X-min) the drag chain itself will hit the control box located on X-min side, and then the mount for it would also collide with the control box. Only way I see this working for control box on X-min side is to have cords enter from that side too. If I am misreading this, I’d be thrilled to be proved wrong. Again, I think the same issue is also present when vac hose is guiding the cords.
