The Six Myths of Stage Error Mapping

Stage-error mapping – measuring absolute positioning error at a specified set of sampling points – has gained a reputation as a method for achieving high-accuracy motion control with lower-cost equipment. The theory is sound. The problem is that there are a lot of misconceptions around stage-error mapping that can lead to its use in unsuitable applications, with disappointing results. Want to dispel the myths of stage-error mapping and learn how you can use it for maximum benefit? Read on.
