Hi Neale , and nice to hear from you again. Sorry if you feel that guru is too strong a term (I did not set out to cause embarrassment) but your colleagues on the stand on that day clearly felt you were their specialist , and therefore the man to advise me . I certainly appreciated your advice . Thanks again

While UCCNC will be an interesting sideline for me, the urgency has abated due to the fact that Mach 3 seems to be working for me at the moment.
I still do not fully understand why but I suspect that the quality of Kit was my main Issue, so am keen to explore that topic
I can see that this thread has now run its course, so maybe i need to start a new one for advice on which kit will give me a robust control system .
