A method determines translational and/or rotational deviations between the measurement coordinate system of a measurement mirror scanner and the processing coordinate system of a processing mirror scanner. A measurement beam reflected at a workpiece returns on a path of an incident measurement beam and is captured by a spatially resolving measurement sensor to ascertain spatially resolving information of the workpiece. The reflected measurement beam, in a sensor image of the measurement sensor, is imaged onto a previously known image position. This is accomplished by ascertaining a focal position deviation of the processing beam by scanning with the processing beam, evaluating a laser power detected at grid points, fixing the processing mirror scanner, capturing spatially resolving height information of the pinhole diaphragm by the measurement sensor, and determining a translational deviation between the processing and measurement coordinate systems based on the deviation.

A sticker for spacing wood is extruded from an aluminum alloy. The sticker can have different configurations. In a first configuration, the sticker has a width about the same as its height, with longitudinal ridges on all sides that grip wood when wood is stacked on the sticker. In a second configuration, the sticker has a width significantly greater than its height, with longitudinal ridges on the top and bottom surfaces, and with smooth side surfaces. The longitudinal ridges have a height within a specified range and are spaced at a distance peak-to-peak within a specified range. The ridges provide good grip of lumber stacked on the sticker yet do not easily plug with wood fibers through repeated use. The extruded aluminum sticker is very rugged and can be used for hundreds or even thousands of drying cycles.
