Thanks, JAZZCNC,
Well, the good news is that I have found the fault, turns out that removing the lid of the case and pushing the scope probe into the connector crimps recreates a circuit on the direction pin (now soldered, not best practice)! the worrying issue is that most of the crimps are very poor. I am supprised this was not picked up in quality control or inspection before the units final assembly. The machining of the case lid is appaling and in fitting back together puts even further strain on the connectors. ironically cutting the tywraps eases things cable wise. I have ordered connectors and crimps and will remake the interconnects.
Thanks so much for everyones help and suggestions, my next challenge will be to solve the licence issue.
Cheers,
Sashido
