A multi-axis fatigue testing device includes a multiple input, multiple output mechanical linkage driven by a plurality of actuators and a controller operating each of the plurality of actuators in real time and in synchronization to produce user-defined multiple fatigue cycle profiles. A startup method enables a sample mounted at an arbitrary multi-axis state to receive a desired simulation profile while maintaining the sample below any of the extremum values of the desired simulation profile.
