This is something we might be able to implement on our SL-10 which drifts about 0.0015 on diameter while warming up. We know more or less when to adjust the wear or offset to compensate and do it by hand now.
On the topic of macros do you find that the technical schools teaching programmers down play the usefulness of macros? I sent a guy on a sixteen week course and whenever he started asking about macros the answer was: "you don't need macros. they are old fashioned, use CAD/CAM it's a lot easier". Needless to say he didn't learn anything about macros.
