Adjustment method of zoom module：
1.Before adjusting the focal length, prepare a dimming lens or protective glasses for filtering and observation.
2.Place the object to be carved under the laser and adjust the height of the laser to keep the distance between the light exit and the surface of the object at (30-50mm).
3.Turn the focusing head to adjust the focus until find the point.
a.However, it should be noted that the focusing range of different laser heads is different. For details, please refer to the corresponding lens description on the wiki. For the distance under normal circumstances, the light exit distance is 30-50mm (40mm) from the engraving object.
b.If the surface of the carved or cut object is uneven or in a white and transparent state, it may cause the user to have no way to directly observe the focus state. In this case, you can use a thin gray cardboard on the surface of the object to help adjust the focus.
c.If the low-light brightness is inappropriate, you can adjust the low-light status in the software's settings page.
d.NEJE is equipped with a short-focus lens with a focal length in the 5-50mm range. The 3500 and 7w come standard with this lens. The closer the lens is to the light exit, the smaller the focus point. But there is a disadvantage: the burning smoke tends to blacken the lens. If you are trying to use this kind of close engraving or cutting, it is recommended to add an additional fan on the side to blow off the smoke and avoid contaminating the lens. If the smoke contaminates the lens, it may easily cause the lens to break. At this time, you need to purchase an additional lens to replace it. If there is no break, you need to clean the lens with a cotton swab.
