ok, so works like my other macros for finding the center of a hole or bose feature, (both of which i have used successfully) ill explain the hole finding macro, first you place the probe inside the hole so that the ball is below the surface and lets imagine i used g114, so now id input g114 d(approximate hole diameter) x0 y0 h(work offset preffered) press enter and cycle start in MDI mode. then id have the center of the hole displayed in guaging results..
