When you get bolt-bound or base-bound on a critical machine train,  usually one that is very difficult to move,  it is not enough to just be able to fix individual pairs of feet to obtain alternative shimming or moving solutions. You need even more flexibility: the ability to minimize moves across all the feet. The concept of stationary and movable machines is obsolete: All machine feet are movable under given circumstances, so it is essential to be able to find the minimum corrections necessary to align to any conceivable centerline, including fully optimized centerlines, or centerlines optimized among any desired number of fixed and movable feet in any combination. Such flexibility is imperative when working with machinery on the critical path. Therefore, look for this capability when selecting your next laser alignment system.
