And either excessive compensation or not enough. When I get this together enough that I can chuck up 1/2" rod, make a test cut to see how far off I am and then make what I think ia n intelligent adjustment to the X axis HOME_OFFSET, I think the 1st thing is to make my homing gauge a 3 point. As it is, I can also use it to measure how much vactra is on the ways as it has about 3 square inches sitting on the level rear of the bed. So I'll ball nose a set screw and use it for a single contact resting point to see if that reduces the repeat errors. Too easy to get a contaminant under it the way it is, which tips it fwd. > I never use anything else, and I am fairly careless with tool offsets > much of the time (pushing the parting tool out for more reach and not > telling the tool table) This does bring up another question though: Is there a formula to derive the ideals in The Machinists Handbook?
