Thanks again Andy. It worked. Even thought my speed control (mc-60) is cheap and low-tech, I am able to make the speed track better than +/- 5% from 20 to 1200 rpm under reasonable thread cutting loads. That ain't bad for recycled junk.
This exercise with the 5i25 and 7i78 has forced me to get a whole lot deeper into understanding the concepts and syntax involved in hm2 and hal. That is a good...but sometimes humbling... thing.
