My SL10 will not repeat within .0002 without someone right on top of it to change offsets. Just won't do it. Steel, Alum, Stainless. Don't matter.
My Daewoo on the other hand will with no issues what so ever.
If doing close tol stuff, I wouldn't even think of putting it on my Haas. I do lots of other production stuff that it does well. But close work ain't one of em.
Not bashing Haas. Just telling the truth. My little Minimill does great. holds tol very well. My SL10 does not. Now this could well be just my machine. But it's the only Haas lathe I own, and I'm not likely to own another one to see if I was wrong or not.
