METHOD FOR OPERATING A LASER PLOTTER FOR CUTTING, ENGRAVING, MARKING, AND/OR INSCRIBING A WORKPIECE, AND LASER PLOTTER FOR ENGRAVING, MARKING, AND/OR INSCRIBING A WORKPIECE
The invention relates to a laser plotter and method for operating a laser plotter for cutting, engraving, marking and/or lettering a workpiece, in which at least one irradiation source in the form of a laser is used in a housing of the laser plotter, wherein, when the irradiation source is activated, a laser beam is directed via deflection elements to a focusing unit, wherein a control unit performs the control on the basis of the set parameters and/or a loaded job, wherein preferably a processing table or a processing chamber is detected via at least one camera for recording an inserted workpiece. The data, in particular job, are received via a computer unit, and a calculation of the path planning is performed offline by the computer unit or externally by a cloud solution or component, whereupon the path planning and other data are transferred to a PLC controller (26a) or soft PLC (26b), from which at the sampling cycles or sampling times, the individual target data, in particular the path planning and other data, such as the speed, are then sent step by step via an industrial bus, in particular an EtherCat bus, to at least the modules for axle control and laser control, wherein at least the detected position and speed information, in particular the axle positions and speeds, are sent from the axle module to the laser control module at the cyclic sampling times, whereupon an estimate or calculation of one or several future axle positions at future points in time is performed by the laser control module or by a universal board, in particular by the universal Trotec board, in order to activate a control signal for the laser control in good time, in particular for activating the laser at the predetermined estimated axle position of the focusing unit.
