Features
•Hybrid compression technology makes the focal point of NEJE E80 0.1x0.1mm,
and the power density reaches 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. Compared with other 20W
modules, NEJE E80 has great advantages in terms of lifespan and performance.
•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) makes the performance of E80 is much better than that of
similar 20W and 40W 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.

FAQs
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: 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.
Q: Is the Atomstack 130w laser module the same?
- The NEJE E80 is different from other 20W (130W is the power adapter) modules. Usage
details vary greatly. If only the power was required, the NEJE could have been 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. Hopefully time will vindicate
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 watch. Fortunately, NEJE has the support of many professional users.
Q: What exactly is HYBRID TECHNOLOGY?
In fact, this problem is more complicated. The ordinary module only uses FAC lenses to
conjoin 4 beams, 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 fundamental problem with this solution, that is, the life of the LD will be

curtailed, which is the reason why NEJE has not launched new products. The 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 manufacturer, and why NEJE can provide after-sales service as
standard. 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. Power on M7 and M8 NEJE modules connectors are still 12v even if the main NEJE 3
MAX board is powered at 24v
2. NEJE AF3 and relay modules can work in 12v or 24v.
3. NEJE AF3 and relay modules cannot 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.

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!
Please wear protective glasses before operation!
Please do not touch the laser outlet with your hands. It may burn your hands!
Please avoid strongly impact on the machine!
Children under 14 years of age are prohibited from using this product!
Children over 14 years of age need adult supervision when using this product!

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.
NEJE E80 recommends using NEJE Max 4 equipment control, through variable Z-axis multi-
layer sinking settings, cutting from the material surface layer by layer to achieve high
efficiency cutting.
Operation steps controlled by the Z-axis:

1. Reset the motorized Z-axis in the direction of Z0;
2. Find the focus position of the module, and record the distance between the focus and the
module;
3. Install the module on the motorized Z-axis, and set the focus position The distance to the
honeycomb board is set as the electric Z-axis travel distance, (the distance from the module
to the honeycomb platform = the distance from the focus to the module + the distance from
the focus to the honeycomb platform), the LightBurn software sinking setting parameters =
Z-axis travel - material thickness, the first One knife focus is set on the surface of the
material.
If the Z axis of your machine is fixed, it is recommended to adjust the focus to the upper
middle position of the material when cutting the material and repeat the cutting one or
more times.
How to quickly find focus by observing low light?
1. 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.

Note: (Number of Passes - 1) * Z step per pass < 7mm (The standard air nozzle is designed
for cutting less than 17mm. If you want to increase the cutting of materials larger than
17mm, you can increase the cutting thickness by replacing the plane protection head +
metal air pipe.)
The NEJE E80 module adopts NEJE's unique hybrid technology. Compared with similar
products, the 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.
When cutting, according to the performance of the controller (synchronous belt equipment),
it is recommended that the cutting speed be greater than 10mm/s to avoid burning the
material. NEJE E80 has very reliable continuous working performance and supports 100%
power continuous working, but please pay attention to prevent the risk of fire. NEJE Max 4
door function can be used to extend the flame sensing and emergency stop, terminating the
job.

About air assist
NEJE E80 is equipped with 2 high-temperature-resistant (1000°C) protective lenses, which
can be replaced. Pay attention to regularly cleaning the surface oil and foreign matter
according to the actual use case. Oil and foreign matter sticking to the surface may cause
high temperature to soften the lens.
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. Stainless
steel pipe air nozzle, this method can use oily water air source, easy maintenance, and can
quickly clean the lens, the metal pipe needs to be aligned with the focus.
When cutting mdf, leather and high-density materials, it is necessary to add air assistance
with a pressure of not less than 30psi.

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. Generally, for depth of engraving less than 1mm, and the
cutting of plywood less than 2mm air assist is not required. A small fan can be used to blow
off the smoke generated by the engraving. Air assist is not recommended when engraving
images, and adding air assist at this time will destroy image details.
What kind of air pump is suitable for cutting?
The main function of air assist is to blow off the carbonized material produced by cutting,
and the general oxygener and electromagnetic inflator have almost no meaning. only the
pressure of the oil pump and air compressor (0.4-1.5mPa) has the effect of blowing away
the carbonized material. but it should be noted that the air of the oil pump contains oil and
cannot be directly used for the air-assisted module of the closed cavity, otherwise the oil will
contaminate the lens, resulting in power drop or damage to the lens. The air pressure of the
air compressor can be used for a short time with the closed cavity, but when used for a long
time, the water-containing gas will contaminate the lens, cause the power to drop, and even
damage the lens.

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. 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.
