Method for the start-up operation of a multi-axis system, wherein the multi-axis system comprises, as components, a number of segments, which are connected via respective joints and are movable by a controller (20, 21) in one or more axes, and a tool, which is connected to one of the segments and is movable and drivable to a specified position by the controller (20, 21), in which - a plurality of optical markers are arranged in the environment of the multi-axis system; - position coordinates of the optical markers in a first, global coordinate system are ascertained and stored in the controller (20, 21); - the environment of the multi-axis system having the plurality of optical markers is captured in the form of image data by a camera system, which comprises at least one camera (27, 28); - the image data of the camera system are transmitted to an augmented reality system and visualized in an output apparatus, characterized in that - in addition to the optical markers that are contained in the image data, virtual markers are represented during the visualization of the image data, wherein a respective virtual marker is assigned to exactly one of the optical markers and the position of a respective virtual marker in the visualized image data is obtained from a transformation of the position coordinates of said assigned optical marker from the first, global coordinate system into a second coordinate system corresponding to a position and orientation of the camera system; - a check is carried out as to whether an optical marker and the assigned virtual marker overlay one another in the visualized image data and in which - image processing is provided which detects a mark arranged on each of the components in the visualized image data and; - for each of the components, one bounding body (11H, 13H) is defined and assigned thereto, wherein a bounding body (11H, 13H) that is assigned to a component encloses the assigned component, in particular completely; - during a movement of the multi-axis system in space, the position of the bounding bodies (11H, 13H) in the first, global coordinate system is calculated and transformed into the second coordinate system corresponding to the position and orientation of the camera system, wherein the bounding bodies (11H, 13H), which have been transformed into the second coordinate system are visualized in the AR system together with the image that is recorded by the camera system and comprises the mark of a respective component; - by evaluating the movement of a respective mark of the component and the movement of the assigned bounding bodies it is checked whether the bounding bodies follow their assigned component during the movement. - a plurality of optical markers are arranged in the environment of the multi-axis system;
