4. Adjust the focus
Press up or down button to lift or lower the laser head until the 2 red light point overlap, which is the best
focal point.
The measuring focal length of this machine is ___________ mm (70x70) and _________ mm (150x150),
and the measuring distance is the length from the middle line of the Galvo to the surface of the engraving
material. This parameter is measured manually, and each device has different focal lengths due to changes
in laser sources and field lenses.
Note:
*The overlapping point should be on the marking material other than the surface of the machine.
*Red light correction before shipping. At the position where the 2 red light spots are focused, the laser emits the
strongest light. However, due to transportation reasons, the focus point of the red lights you received may shift,
and the focus point would not be the best focal length.
Please follow the steps for debugging.
1.Place the stainless steel test plate on the machine
table
2.lift up or down the laser head to the best focus
point according to the number in handwriting above
