Abstract
Besides the industrially widely-used galvanometer scanner for laser marking especially flatbed laser engravers and cutters are well established in graphic and design branches. Compared to the vector based technology of galvo-systems most of the laser engravers are based on pixel data produced out of graphic-or photo-programs and mainly engrave large scale areas such as signboards or printing plates. The human organ of sight is very sensitive to unwanted picture effects or distortions. In order to get rid of such disturbing effects a flat bed laser engraver of a technology leading company has been analyzed to find out these errors, identify possible causes and ways to eliminate them. In addition to this vector image processing and cutting of non metal sheets is also an important feature which could be improved by modifying the motion algorithms. During this investigation the whole laser machine was reduced to a model in MatLab including the laser source, motion system and material data.
