Summary of Contents for NEJE E80
- Page 1 Packing Contents...
- Page 2 2400W/mm², Compared with *tool 40W module,power density:1777W/mm² (0.15x0.15mm,8xLD,Current highest power) , the performance of E80 is 35% higher than the 40W module. Due to the extremely strong power density and optical design, NEJE E80 has more excellent performance when the power is halved.
- Page 3 Q: Would this fit straight into the existing frame for a40640 master 2 max? NEJE 2S Max is not supported, if you have NEJE 2S Max, then you need to upgrade to NEJE 3 Max. NEJE 3 Max is supported, but you need a 24V power supply for the E80 laser module.
- Page 4 I really want to tell users, don't just look at the parameter of power, do users only need the laser to burn? Q: If I connect the E80 with the 24v power supply in my NEJE 3 max, can you confirm the NEJE air valve AF3 and the relay will continue to work fine? I see 3 options: 1.

Page 5: Installation
Installation Install the module height adjuster on the z-axis and adjust the module height and focus by adjusting the M5 Allen key to slide the module up and down. Safety Please do not leave the equipment when the equipment is working, long-term stay may cause the material to burn！... - Page 6 Focus E80 is a fixed focus module, the fixed focus position is 25mm away from the body as shown in the figure below. E80 is a quasi-industrial-grade fixed-focus module. Unlike CO2 lasers, the 450nm semiconductor laser is visible, and the intensity of weak light can be set. Observe the minimum focus by observing the fluorescence reflected on the surface of the grey cardboard through protective glasses Location.
- Page 7 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.
- Page 8 Put a grey 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.

- Page 10 NEJE module has a smaller focus angle and relatively uniform XY symmetry. It is the perfect work of NEJE after summarizing almost all 4xLD solutions. In use It can prevent the material from igniting. However, too slow a speed setting and unreasonable focus adjustment may cause the material to catch fire.
- Page 11 NEJE E80 can use 2 types of air assist. a. Conical air nozzle in the inner cavity, this method needs to use oil-free and water-free air source, (Note: ordinary oil-water filters can only filter simply, not completely, and need to be cleaned regularly built-in protective lens) b.

Page 12: Specification
The air nozzle must be aligned with the cutting port to blow off the carbonized material, otherwise it will be ineffective. When do you need air assist？ Air-assisted engraving or cutting should only be used for engraving or cutting that produces more carbonized substances. - Page 13 ESD Design: Yes Temperature feedback: Yes Recommend Cutting & Carving Depth: <16mm (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.) Stainless Steel Carving: Yes 0.1mm Stainless Steel Cutting: Yes...
- Page 14 Connect 24V and GND pin to 24V power, ensure the power adapter is sufficient, 3A-5A is recommended. Connect TTL/PWM pin to your control board PWM output pin. E80 driver has very high conversion efficiency, input 65W can output 24W optical power. FAQs Inferior power supply leads to the problem of laser power drop! How to test my laser module?

12V mode, and there is no problem with indirect use. It is recommended to connect other devices through the control board, and it is recommended to use the device with Z-axis control, which is conducive to the full performance of the E80. Maintenance 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.
