One of the issues I seen was that the wires are too tightly crammed into the cable guide and rubbing badly. They where also unshielded and I'm sure some of the trouble was electrical noise was interfering with the steppers because when changed for shielded cable the machine was much smoother and sounded loads better.?

No it's the bit that's fastened too the gantry cross brace.

How long running before this starts happening.? Also is the noise I'm hearing there all the time or does that come on after time has well.?
