Re: RE: DRO UPDATE

Terry,
Thanks for the words of encouragement. I need that and hope my little bit
will help. I appreciate all the words that I have gotten on the site and as
things progress, will try to update it. My long term goal is to get to the
magical resolution of 0.0001"
Actually, when I started the goal was to get accuracy to 0.001" with no
backlash. I have far exceeded that but now it is a challange.

Please let me know if I can help further.
