Well I suppose a smart arse would point out that network cables aren't exactly industrial grade flexible cables, being single core etc. In my own defence, I only used it in my own system within the cabinet for the short distance between the line driver and the DG4S drive.

Good you found the issue in the end. It could have been even more intermittent which would have been even more frustrating. With intermittent faults you can never be 100% certain you've found and fixed the issue.

That cable sounds surprisingly crap if it has multiple breaks straight off the reel. You need to get the whole thing out of the building and into a skip where it belongs before you use any more of it now or in the future.

That video of swarf can only be hours away now - looking forward to seeing it in action!
