Abstract
The present disclosure relates to a laser plotter, a galvo marking laser and a method for defining a laser control signal for a laser source for various types of laser machines, for cutting, engraving, marking and/or lettering of a workpiece, in which at least one laser source is used in a housing of the laser machine type for processing a workpiece. A PWM signal for controlling the laser source is generated by a control unit. The workpiece is deposited on a processing table and the processing of the workpiece carried out line by line, whereby a separate PWM signal for driving the laser source is generated for each line. At a defined edge, a correction process is carried out to generate a modified PWM signal, wherein the correction process determines the preceding pause duration and the pulse duration, from which a correction value and a correction factor, respectively, are determined.
