Hi Hood
My apologies, despite my statement that it worked well on the PP, your advice pushed me to retest it again.
You guessed it the hesitation was also on the Parallel Port... extremely embarrassed on my behalf.
I have a convoluted series of excuses but in the end I just better to move on and thank you for your continued assistance.
You managed to get me to recheck my assumptions and I thank you for that.
The only thing I will say now is I have seen it work many times very well on feed rate overide and it's up to me to retore it !!
Regard
Ross
