Scharged : Glad the tool setup and referencing worked. That is the way they explained it at tormach.
My unit is usually within .002~ on initial setup. I think my home switches are pretty tight. I just reference tool one and everything stay pretty tight.
I have use the 3/4" bar trick to line up my gang tooling to get it centered. I purchased a concentric dial indicator to get it closer. It really helped when I added another ID turning holder to the turret before I bored it to 3/4".
