NEJE E80 Laser Module Description & Detail


Install Support


The E80 is a 4xLD module designed primarily for large stock removal and powerful cuts, yes it’s a cute and rough guy, powerful but attention to detail. HYBRID Technology (Non-Destructive FAC and Combined Compression Laser System Technology) let the performance of E80 is much better than that of similar 20W laser modules, with smaller focus, smaller angle, XY symmetry, and differences in laser systems, which can bring a completely different experience, not easy to catch fire and cleaner edges , it can even cut high density materials without air assist, for cutting thick wood, this module may be revolutionary. E80 has very reliable stable performance and longevity at the same time, the service life is longer than Ordinary 20W modules are 50% higher, material process selection, thermal calculation and testing, NEJE has experienced 3 years of reliable verification testing and 10 years of manufacturing experience, summed up the design experience of diode lasers to create a reliable E80.

NEJE summarizes the advantages and disadvantages of various optical system design methods. After 3 years of research, a perfect 20W laser system with complex and unique technology is finally adopted. The new laser system adopts external FAC and lens compression composite technology. The complexity is more than 3 times higher than that of ordinary 20W modules, so it has better optical characteristics than ordinary 20W lasers. X and Y have good symmetry in each focal length, and the focal energy density is 400% higher than ordinary 20W modules. , the divergence angle is reduced by 50%; and these can bring about cleaner cutting edges, faster cutting efficiency, not easy to catch fire, smaller smoke, more durable and reliable service life, and more comfortable experience. NEJE pursues perfect products and insists on 2 years of free warranty and establishment of a complete after-sales process. In order to maintain the goal of user value, we postponed the release of 20W-level new products for 2 years, but for the goal pursued by NEJE, we should insist on making a perfect module. You can start booking now, NEJE fans.

NEJE will release more videos to beginners. In fact, we only released a short test video, which can explain many things. The symmetry of XY, the focus power density, and the divergence angle. This is to complete the cutting of medium density plates without the assistance of home air. If the 20W modules of other families are tested, most of them are directly on fire, which is the difference.


Q: Will I have to do anything for it to fix to the NEJE 3 max?

-NEJE 3 Max V1.1 and above can support this module, 24V5A power supply (please pay attention to the motherboard version).

Q: Any power test will happen? It is saying 24w?

-Optical power 24W, electrical power 80W. 

Q: Iwould this fit straight into the existing frame for a40640 master 2 max?

-NEJE 2S Max is not 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 E80 laser module.

Q: The atomstack 130w laser module is the same?

– The NEJE E80 is different from other 20W ( 130W is the power adapter) modules. The use details vary greatly. If only the power is available, the NEJE can be sold three years ago. Those who have used Xtool or At can see four beams of light with a large focus. These optical systems are simply stacked. The NEJE uses more complex optical systems inside. The reliability and performance are different. Maybe time will prove everything. NEJE has established a 2-year warranty after-sales process, and we don’t want to have any loopholes in our products. I suggest you refer to the actual work effect. NEJE will update more actual carving and cutting videos of different materials later, which you can pay attention to it. If you are also attracted to the 130W power adapter, they succeeded. I can’t describe professional optical engineering design, maybe NEJE needs to provide more material processing videos to describe these different supports. Too many cool videos and parameters are very popular among users, and NEJE is also very helpless. NEJE focuses too much on the perfect optimization and reliability of products and ignores marketing. Fortunately, NEJE has the support of too many professional users. 

Q: whats is exctaly HYBRID TECHNOLOGY?

– In fact, this problem is more complicated. I still try to explain it as much as possible. The ordinary module only uses FAC lenses to piece together 4 lights, which will cause a problem. The included angle is relatively large and the focus is relatively large. Of course, if compared with CO2 laser, This is still acceptable, but there is a fatal problem with this solution, that is, the life of the LD will be destroyed, which is the reason why NEJE has not launched new products; but NEJE E80 adopts a more extreme solution, and NEJE adopts a more advanced external FAC, first combine the two beams, and then combine them again through the lens system. This way the angle of light is smaller and the focus is smaller. Two lens technologies are applied here, and the manufacturing process is much more complicated. However, the effect is very different. In fact, the manufacturing cost of E80 will be higher than other 20W lasers (optical power), but NEJE is the manufacturer, and other merchants are third-party modules purchased by marketing companies, which is also the advantage of NEJE as a full-stack design and manufacturing, and why NEJE can The reason for providing standard after-sales process. I really want to tell users, don’t just look at the parameter of power, do users only need the laser to burn?

Q:lf I connect the (futur) E80 with the 24v power supply in my NEJE 3 max, canyou confirm the NEJE air valve AF3 and the relay continue to work fine ?
i see 3 options:
1) Power on M7 and M8 NEJE modules connectors are still 12v even if themain NEJE 3 MAX board is powered in 24v
2) NEJE AF3 and relay modules can work in 12v or 24v.
3) NEJE AF3 and relay modules can not work in 24v.

-The relay can normally use 24V power supply. If you need to use the air valve, it is recommended to replace the 24V power supply. The gas valve can also be powered by 12V for short periods of time. Over time, increased temperatures may affect the life of the air valve.

    Good afternoon, I have a Master 2S Max unit, from the Engraving Area:
    460*810mm, the controller card is damaged the same as the 40630, I want to buy the E80 module, the card is damaged, the frame and motors work for me? and what card can i buy to use the frame and motors i have, thank you very much.

    Buenas nochesn, estoy interesado en el 3S MAX, tengo el marco de un 2S MAX, me descontarian algo sin el marco? es factible el #S MAX con el E80, que valdria, gracias

  3. I have the Neje 3 Max with 40640 (Twin Fan module), approx 6 months old so assume this upgrade to E80 module should be straightforward. However a little confused about the adapter boards listed. Does this mean these boards are required in addition to the existing main board, what I do not want is a mass of wires and add on boards. Ideally I would expect a straightforward plugging in of the new 24v powersupply, swapping the 40640 for the E80 and thats it, done.
    A schematic of the actual setup would be usefull before I spend this amount of money on what is currently an unknown item, I am also in the middle of preparing a video of my experience with the Max 3 and would possible see this as a later update of that video. I should add that so far I am more than happy with the Max3.

    1. NEJE 3 Max V1.1 and above can support this module, 24V6A power supply, just replace the module directly (please pay attention to the motherboard version).

  4. Do you have a schematic part that shows the PWM internal input circuit for the E80?
    I need it because i want to check if I can use the open-collector PWM output of my CNC controller or have to add a pull-up resistor.

    1. The E80 has two air-assisted modes. If there is a clean air source, you can use the built-in air-assisted mode. If there is no clean air source, you can use the needle-type air-assisted mode.
