I have put together another zip file which includes the above macro, original file by author "unknown", and my write up, with what I could think of as "pertinent information. I am not sure yet as to how complete it (my write up) is and it is to be considered a work in progress, and more features may be added. Also please note that this is set up as I have my machine setup and for the most part I believe very close to the way IH sets up their mill systems in Mach. I tried to note all the specific areas that need to be considered critical for operation and safety but I may have missed something somewhere. The macro works perfectly in my machine now and I am very happy with it and the repeatability with the Minear probe is showing in the neighborhood of .0003" which makes me very happy.
