Thanks for the advice you're absolutely right I started this thread from a position of just about compleat ignorance.
my knowlege has increased a lot but still has a way to go.
I expected there to be both positive and negative comments, in life I have to find the good ideas from the bad why should here be any diferent.
As for using a laptop and having problems withthe power saveing features I think I've switched them all off the laptop was switched on at 12 at 4 it was still going strong no screensaver no switch of no nothing it was still going at full power. I will still have to prove it with the Cnc but things are looking good.
will post again whe I have tried the uc100.
