Abstract: The present invention discloses a method to calibrate a laser cutting machine without stopping the production. The method is adapted to laser cutting machine which use a conveyor belt to convey the sheets while cutting them with the laser. The method allows to place calibration marks at locations on the sheet that are convenient according to the production job, thereby minimising the waste of material.
