Table track installation (done my way) provides a tighter fit to back wall

I know the instructions call for the cable track rigid (fixed) end to be connected cable track bracket but after seeing a problem with doing this, I did the opposite and attached the flexible end to the bracket. Here’s why:

Before I bought my machine, I had AVID send me a 3D CAD model of the CNC PRO4848 so that I could insert it into my 3D assembly of my shop. I located the back legs of the machine, 6” from the wall. At first, I was concerned that the cable tray on the gantry was going to hit the vertical dust collection pipe on the wall. It didn’t. I didn’t take the time to create the machine model to be animated with assembly joints to show motion. I was more interested in “space claim” of bodies.

I noticed during my build, the table track would hit the wall and the Y2+ sensor was about 1-1/2” away from the sensor flag, when the track was installed according to the instructions.

When I reversed this and attached the swivel end of the track to the track bracket, I gained the room that I need to make the Y2+ sensor in range with the sensor flag.

I was going to provide several pictures, but being a “newbie”, I’m not allowed to attach more than 1 photo! Booo!

Guys need to see the before and after results!

If anyone is interested in viewing the pictures, contact me and I will share if possible on this forum.

The reason you normally don’t do this is because you’ve created a sharp bend point at that swivel. The purpose of a cable chain is to prevent such bends. While it will probably work, keep an eye on the wires at that point to make sure they’re not going to prematurely fail.

I completely understand the logic of some cables and wires require a minimum bend radius. I visually inspected this, and I believe that the radius isn’t that sharp but I will definitely keep an eye on it. And if need be, I’ll get a carjack and move the machine out from the wall slightly and reverse the track the correct way.
