A machine tool installation for laser cutting of sheet workpieces has a workpiece support, an elongated machine frame providing an arm extending over the workpiece support, and a track on the arm which extends longitudinally of the frame. The stud bumps respectively pass through the vias and electrically connect the electronic element. The receptacle includes a wall having a working surface that is used to spread the liquid over the treatment surface. The host initializes the data storage drives providing initialization data to the drives where the data may include position information and commend information. If, however, the original data would be overwritten by the presently requested write operation, then an area containing the original data is copied from the selected volume to a temporary volume.
