NEJE 5 is ready to use right out of the box.

It can be placed directly on a tabletop or fixed on a flat surface for better motion stability. If you need to use it for cutting, you can place a metal plate under the honeycomb bottom plate to prevent the laser from damaging the tabletop.

NEJE 5 DIY laser engraving and cutting machine has multiple safety protection measures to enhance safety protection capabilities.

1.The standard laser of NEJE 5 is 450nm wavelength, which is a kind of blue light wavelength contained in the display screens and sunlight we see every day. Many newborn babies also have a blue light irradiation treatment method, so we don’t have to be afraid. Correct understanding of this tool is the basis for safe use.

2. First of all, the laser engraving machine is a light industrial product. It is a tool that focuses light in one direction. Its focal position may cause harm to the human body. Just like when we use a drill press to process wood, we need to wear protective glasses to prevent splashing, wear protective masks to prevent sawdust from hurting the lungs, and also need to know how to control the equipment correctly. We need to understand these in advance before operation. Safely control them to process the process effects we want. NEJE 5 is a semi-finished industrial component. Since its cutting volume is not large, most users will also use it for secondary transformation, so they don't need to wear protective glasses and masks.

3. Laser engraving equipment will start the laser during the wood processing process. The laser will produce harmful smoke when it interacts with the material. The amount of smoke is related to the amount of cutting. In addition, we need to pay attention to the fire hazard caused by improper operation of the material. In addition to personal protection, we must also pay attention to the harm to small animals, such as cats and dogs.

4. NEJE 5 has many safety designs, including vibration detection, physical shielding on the basic module, and the DOOR function can expand the functions of flame detection, emergency stop, key locking, etc. The standard version of NEJE 5 is Class 4 laser safety level. If you place it on the workbench at home for long-term use, where children or pets can easily touch it, we recommend that you DIY a protective shell for more professional protection to avoid risks. If you are already a professional user and usually store the device, then fix the device on the table when using it, then you do not need to make a shell under the premise of ensuring 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！

Avoid accidental touch by pets！

The standard A40630 module lens can adjust the focal length by a flat-blade screwdriver.

The picture shows the adjustable focus module A40630. For example, if the position is adjusted to a gap of about 2.5mm, a relatively short focus position can be obtained for engraving or cutting. You can also not adjust it. The relative long focus position has a longer light waist. You can adjust it to the focus you are used to as needed. The closer the focus, the better the engraving effect. The medium-long focus has a relatively better effect on cutting thick materials.

For example, if you usually use 3mm material as the distance between the module and the engraving material, you can adjust the focus to a position 3mm away from the module. You only need to put a piece of 3mm material between the material and the module to complete the focus.

You can observe the weak light focus size in the window above the module.

The new module height adjuster can be opened and locked quickly without the need for additional tools. It contains a rubber strip inside to firmly fix the module, and the operating wrench can be pulled outward to adapt the operating angle.

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.

–Why NEJE software does not require cross hairs？

Many traditional users have a cognitive inertia that laser equipment always needs crosshairs for positioning. However, for diode lasers, it is a visible wavelength, and even IR lasers can be combined with red lasers to help positioning, so this is very different from CO2 laser equipment. When the NEJE team designed the first diode laser 10 years ago, they used the weak light display as a positioning operation method by designing firmware. The weak light position is the actual laser position, so it can innovatively control the engraving position accurately through point positioning and box positioning.

E80 is a 24V module, the input power should be changed to 24V.

Support E40, E30 modules

Classic N30610 module, extremely small focus, more refined

B30635 module, excellent grayscale engraving of portraits.

All other NEJE 12V modules and 24V modules are supported.

NEJE5 series, engineers have achieved a smooth and reliable operation experience for large files such as grayscale images in BLE and classic Bluetooth modes through data compression algorithms, packet loss prevention algorithms and hardware capacity improvement. This day has come, we can use our imagination and creativity in front of the comfortable office computer, and data execution can be automated and completed in the device studio.

Normally, a lightburn software can only control one device in real time. Then NEJE engineers skillfully combine multiple devices with lightburn and laserGRBL software to achieve fast management and project production of multiple devices. This is the uniqueness of NEJE multi-device management.

REC is an innovative data transmission method invented by the NEJE team for lightburn software. It can directly send the edited data file to the NEJE device before starting the work. Traditional lightburn software needs to transmit data in real time for the device to execute instructions. This process has some uncontrollable factors and data interruption risks, such as USB interface instability, computer failure and other factors that will cause project failure.

One-key start is NEJE's classic and efficient operation method. NEJE5 has built-in NEJE firmware and optimized GRBL firmware. With NEJE's unique USB or wireless REC transmission function, it can efficiently complete the reliable operation of work data, batch processing and batch device management. However, the traditional SD card and USB method not only takes up the computer so that you can't use the computer for other projects, but also has to worry about the unreliability of the USB real-time signal causing the interruption of the work.

Air assist is a complex and specialized field for laser equipment, which often requires different air assist solutions based on the materials, maintenance and process effects we actually operate.

A: When dealing with regular engraving and small amount of cutting tasks, we can use the module's own cooling system to protect the lens through airflow, which can largely eliminate the need for an additional AOC oxygen machine to protect the lens.

B: The needle-tube high-pressure air nozzle can use oil-containing and water-containing air sources as air assist. Through the high-pressure gas assist, when cutting wood or HDF boards, it can cut more efficiently and make the edges more.

C. The cavity-type air-assisted configuration is suitable for oil-free and water-free gas sources. Compared with the needle-tube gas nozzle, it consumes relatively more gas, but is easier to operate.

The above three solutions can protect the lens and enhance cutting to a certain extent, but the lens also needs regular maintenance, which can be cleaned with alcohol and cotton swabs.

NEJE module driver has built-in control program. The module uses high-life and high-speed double ball bearing fans. After more than 10 years of development, it has achieved very reliable electrostatic protection, high life and silent experience. The built-in driver can intelligently identify TTL signals and temperature sensing to ensure the reliable working temperature of the module while keeping the fan in a dynamic balance and silent state.

NEJE software has built-in NEJE firmware and optimized GRBL firmware. This is a process in which the NEJE team and professional users continuously make the product better. The NEJE team provides OTA upgrade services to provide NEJE devices with usage value beyond user expectations.

Professional users can also contact us through the NEJE Feedback channel to continuously create more exciting and interesting features. We value user ideas and feedback, and maybe you are one of the innovative creators of NEJE devices.

NEJE device models have motion parameters set by default. For novices, you do not need to change them. For experienced users, you can optimize the X and Y axis acceleration according to the actual situation to adapt your project in a more efficient way. This requires certain mechanical knowledge and depends on the module you adapt. Don't worry, if you cannot find the original parameters after changing them, you can solve it by re-flashing the firmware.

3 ways to expand the area:

a.Adjust the X-axis screw to increase the height by about 30mm

b.Purchase a modification kit to replace the Y-axis rail, or replace the X and Y-axis rails to obtain a maximum working area of ​​X=290mm, Y=430mm

c.Prepare a standard 2040 track less than 2 meters long, make a set of wires and matching length of synchronous belt with steel wire core, and easily transform it into a super large working area equipment, with the maximum working area reaching X=290mm, Y=1820mm.

The default area of ​​NEJE 5 is 170*170mm. After changing the hardware area by expanding the track, you need to modify the area parameters of the firmware, software, and device.

（You can start watching from the 1 minute mark）

NEJE 5 adopts independent Z-axis expansion. You don’t need to transform the Y-axis into a rotation axis. You can directly lock the Y-axis and expand the rotation axis through the Z-axis. If you are a professional, you can even expand automatic material change.

The NEJE series devices support M8, M7, and Door function expansion. We usually use M8 to control automatic air assist, which is used to assist in cutting or protect the lens. It can automatically control the gas supply when the equipment starts and ends. You can connect M8 through a relay switch or electromagnetic air valve. The M7 function can be configured in the lightburn software and NEJE software to check whether it is enabled. Usually, we use M7 to expand the automatic smoke discharging system, and we usually use relay modules to control the power supply of smoke discharging equipment. The Door function mainly expands safety functions. NEJE engineers have designed expansion functions for flame sensors, emergency stops, and safety doors. The expansion of the Door function can help prevent safety issues to a certain extent By expanding the interface, you can obtain a more automated device that greatly improves operational efficiency and experience in the actual operation process.

NEJE has designed relay modules to support the control of 12-250V electrical equipment and gas valve modules. The modules are all supported by M8 or M7 interface control. You can decide whether to turn on auxiliary functions at each working level through lightburn software or NEJE software. You can turn on auxiliary functions a few seconds before each start of work.

Please select the corresponding voltage air valve according to the input power supply voltage. otherwise the functions of the main board M8 and M7 may be damaged！

NEJE's specially designed 85 ° distortionless 16MP pixel lightburn camera can clearly display details for working areas larger than 1 meter; With this camera, you can easily locate the image on the surface of the sculpted object to improve operational efficiency.
