If the captured image of the camera does not match the position of the actual processing result, you can correct it in the software.
In the case of PC software, the X-axis and Y-axis values can be entered from Settings → EtcherLaser, and in the case of phone applications from Menu → Machine.
If a positive value is entered for the X axis, the laser irradiation position will be corrected to the right, and if a positive value is entered for the Y axis, the laser irradiation position will be corrected downward.
Also, close the height adjustment screw while keeping the top of the laser head in close contact with the laser head fixing unit so that the laser head does not tilt during height adjustment. If the laser head is tilted, it may cause misalignment of the processing position.
