The A40630 is an adjustable focus module. Guide image above is a guide for the best adjustment settings. You can use a flat-blade screwdriver to adjust the focus position. Proper focus selection is a critical factor for cutting. You may need to try more few times. In addition, adding air assist will enhance cutting and engraving results, resulting in cleaner edges and enhanced cutting thickness and cutting efficiency.
Module: A40630, When focusing to 55mm position (lens-to-focus distance), you can get a 0.18×0.18mm focal point and be able to cut material up to 18-20mm (requires accurate focus, 0.6-1.5mpa air assist to align the cut).
When the focus is adjusted to about 33mm from the light outlet with a flat-blade screwdriver, you can get a focus of 0.13*0.13mm, which is suitable for engraving and fast cutting of materials smaller than 10mm.
Low Light Adjustment
Set the right low light to find the focus more accurately.
Adjust the suitable low light through the software. The NEJE mode can be adjusted in the “Settings” column of the NEJE Win software; the GRBL mode can be adjusted in the “Grbl Configuration” of the laserGRBL software, which has been explained above.
Put a gray cardboard on the surface of the white material (such as plywood) as a focus reference to find the precise focus. A fine focal point can be observed through the protective goggles or the shade of the module.
Find the best focus by rotating the lens. If it is a module with a fixed focus, it is enough to find the distance between the module and the object. Usually, we use a certain thickness of material to pad under the module to help find the best position.
Install Air Assist
- Please make sure that the air outlet is aligned with the focus point;
- Cutting MDF board requires 0.6-1.5mPa air pressure to efficiently clean the carbonized material. The MDF board needs high-pressure gas to assist in cutting. The ordinary oxygener cannot provide high-pressure gas.
- The air-assisted module designed in the cavity, try to choose a clean origin, oily or unclean origin may be Causes the lens to be broken at high temperature;
- A40630 modules and modules with similar external air sources can work without air assistance, and the modules designed with the cavity must work under the conditions of increased air assistance, otherwise it is easy to contaminate the lens and cause the lens high temperature rupture;

Max Cutting & Carving Depth: 18mm (The data is tested by NEJE users, and it needs to be done under more accurate focusing and adding correct and certain strength of air assist.) Brushed Stainless Steel Carving: Yes Mirror Stainless Steel Carving: Yes
NOTE: The data below need to add air assist correctly (0.6-1.5mPA) with laserGRBL or lightburn; lightburn: 60mm/min=1mm/sec,S1000=100% Power (In lightburn, the unit is 60mm/s)
12V: Power positive .
GND: Power ground or power negative.
TTL/PWM: TTL = PWM, input 3.3V~12V to turn on laser module, conect to GND to turn off laser module.
Temperature: do not connect, please ignore.
Connect 12V and GND pin to 12V power, ensure the power adapter is sufficient, 5A is recommended.
Connect TTL/PWM pin to your control board PWM output pin.

Although this module adopts internal air-assisted design, long-term use may not prevent dust or a small amount of smoke from affecting the lens. It is recommended to clean the lens with a clean cotton swab. Dust or smoke may overheat the lens and cause the lens to burn out. Re-acquire the lens Will delay your use.
