Unresolved Extruder stepper cable fail (Design flaw?)

My Robo Plus has been down a majority of time for about a month now with extruder stepper issues. I began by thinking it was a motor then went to thinking it was a driver then the ramps. I ended up adjusting my drivers and started a fire and had to replace the ramps

But in the end it was the cable and one came with motor I bought worked just fine with the old motor. Well after a couple of prints that one failed because I attached the other wires to it and it dragged it down to fail.

Robo 3d just sent another and it was running fine. I got one good print.




About four inches tall and it ran the length of the x axis, so I ran another which was to be on the other side:



As you can see this one failed close to the top and was probably the constant left to right movement that caused this to fail again the second day I had it.


I didn't have my wires wrong this time. I had them zip tied close to the machine.

When they say I can build anything for so many inches wide and tal and deep, it seems like anywhere on the X axis should be available but with these weak wired cable I think this isn't true

I will ask Robo for another but it seems like this will continut to happen.

Is there anything that can printed to keeo this cable taunt? Do those cable chains I have seen work? And with a stock extruder?

Is this a design flaw that could always happem?

 

Been printing a lot since last Summer without any wiring issues. I don't have the plus, but can't think the design changed enough to change the way the wiring is routed. This is an unfortunate issue for sure. cable chains are a nice upgrade to manage wiring better. I wonder if you could put some electrical tap around the cable end and the wiring near them to stiffen and protect the ends from bending too much.
