There's one element that is very troubling: the cable break in the middle.
I am supposing that the bowden has triple internal helical wires as low
friction standoffs - and that repeated motion against a wire cut the
cable.

That shouldn't happen....

Unless the run is perfectly straight, any bend will flex the internal cable
each time it moves. Metal fatigue still happens, given enough time.
