> They don't know their own physical orientations... Wait, so even the really high-end gear in high-end names like DMG Mori don't use something like millimeter radar, ultrasound or machine vision to confirm that real-world orientations at least correspond to within a few orders magnitude accuracy of what is expected? If so, then mad props to you machining guys working with such expensive kit without continuous closed loop monitoring conditions; you re-e-a-a-ally like to live on the wild side.
