NEJE 3 MAX, high power double beam laser with large engraving area

The Neje 3 Max is a laser engraving and cutting machine that takes the bet of the NEJE 3 Pro to the next level, boasting a powerful laser of more than 10 W with double beam and a quite generous engraving area, we are talking about 460 x 810mm. As if that were not enough, it includes an automatic air assistance system that improves cutting and engraving results, all in a package whose cost is around 600 euros.

Perhaps its greatest virtue is the engraving precision, which is 0.075mm, something that is possible thanks to the laser that has a pulse of 11W and an optical power of 10W. This allows you to cut and engrave a wide variety of materials, including plastic, cardboard, stone, leather, aluminum, stainless steel, glass, solid wood and more. If you are interested in knowing more details and what results we can expect, here we leave our review.

Design of the NEJE 3 MAX

The NEJE 3 MAX is a laser engraving machine open frame made of aluminum profiles, which are complemented by polycarbonate structural parts and straps, which improve the stability of the structure and improve the smoothness of movement. It should be noted that there are limit switches at each end, so it is possible to work with very precise coordinates.

NEJE 3 MAX - Design

As expected, the NEJE 3 MAX is shipped pre-assembled. We will have to do our part to make it work. However, it is a relatively simple process, just putting 6 screws in the right place and following a few simple steps to get the gantry and purlins into position. Instructions and tools are included with the package, not to mention that there is plenty of documentation online that can help.

In another order of ideas, what distinguishes it from the competition is that its control unit comes with a air valve kit with M8 relay to control air assist, as well as a switch kit with M7 relay to control the smoke exhaust system and emergency switch.

NEJE 3 MAX - Control unit

In another order of ideas, the safety factor has been taken into account in its design, because in addition to having an emergency switch, the machine unit has an antistatic and anti-surge design that does not require an additional ground connection to protect the equipment. Similarly, it has an acrylic shield on the laser module that protects the eyes from UV rays.

Laser module and features

Going into technical details, the NEJE 3 Max features a 2-beam diode laser engraving and cutting module. According to NEJE, this allows working on a wider range of materials. With that in mind, the laser module has a 0.04 x 0.06mm spot size with optical power of a little more than 10W. It should also be noted that the manufacturer promises 80% power (9W+) when cutting for a long period of time.

To be

To put them in context of the possibilities of this machine; The A40640 laser module can achieve grayscale photo-type engraving on stainless steel, as well as stone carving, glass carving, acrylic carving, hardwood carving and more. For its part, the uniform cutting thickness of the module is 18mmso it can definitely cut thick materials like plywood, MDF (8mm), birch (3mm), and black acrylic (5mm).

As we mentioned before, the machine offers a 810 x 460mm working volumeso there’s a lot of potential here for different projects.

Another detail that we cannot overlook is the inclusion of an air assist kit, which removes smoke and dirt from the engraving and cutting area as it is generated. However, an air pump is not included with the purchase, this must be provided by the user.

Additionally, the laser engraver has a air valve kit M8 to control this system. Also included is an M7 relay switch kit to control the smoke evacuation system and a door switch to stop the machine in an emergency.

Connectivity and software

The NEJE 3 Max can be used with the NEJE app available for Android and iOS, but obviously we can also control it from our computer either through LaserGRBL or Lightburn. The mobile app is great, but it doesn’t distinguish between recording and cutting, it all depends on the power and number of passes that we select.

With that said, Lightburn is the most recommended option for this laser machine, as only the starting position of the laser has to be chosen. Similarly, it offers more options than all the previous alternatives.

NEJE APP

It is also worth mentioning that the machine has a 32-bit chipset, which is not normally something to brag about in devices of this type, but the difference is that this enables the NEJE 3 MAX to receive firmware updates via OTA.
