Oh that applies to so many things in life lol. How are you, long time no speak. The CS labs controller has been working great by the way.

It just got me thinking that on a large machine, which is better ballscrew with rotating ball nut or R&P. In my mind (not always the best place to be :-) ) I would think that R&P would be cheaper to implement with better stability and speed (accuracy?) on larger machines. Now I am up for being proven wrong in my assumptions, best way to learn something :-)
