Abstract

A method of calibrating a laser engraver as well as a laser engraver is disclosed, the laser engraver comprising a laser and a camera and a plate for holding a product to be engraved, the plate comprising a reference grid, wherein an optical path of the laser is directed to the plate and an optical path of the camera is directed to the plate and the optical path of the camera to the plate and the optical path of the laser to the plate are at least partially the same before and when hitting the plate, a calibration system with a controller, and a comparator, wherein the controller uses the reference grid of the plate with no product on it to calibrate the camera and wherein a predefined pattern is engraved on a product on the plate by the laser and the camera captures the position of this engraved pattern and the predefined position of the engraved pattern and the position according to the camera are compared and a difference between these two positions is determined and this difference is used to calibrate the laser.
