here is a video of my current set up. Lots of room for improvement but you can see my wire management. I bought 3 of these planning on extending the x and y with the 3rd. My machine is 4 feet a side. I haven’t lengthen the chains yet.
And these are the chains i bought http://www.amazon.com/gp/product/B005GIRT6O?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s02
I could have 3d printed a drag chain but at 10 bucks i felt this was an ok cheat 🙂
