NEJE Max 4 V2 E80 Motorized Z axis Wood Laser Cutter | 1000mm/s Laser Engraver for Wood | Large-area Laser Engraver & Cutter for Metal | DIY Wood Laser Engraving and Cutting Machine

The brand-new Max4 V2 has undergone significant technological upgrades. Please click the blog link to view the details.  What improvements does the Max4 V2 offer compared to the Max4?

Every component of the ​​NEJE Max 4​​ undergoes ​​precise CNC machining center correction​​, ensuring superior accuracy.
The panels and frame are ​​precisely interlocked via grooves​​, while the profiles and linear rails are ​​individually CNC-machined to correct rail flatness​​, guaranteeing ​​perfect alignment and surface precision​​.
The Y-axis guide rails are also ​​CNC-corrected to eliminate profile deviations​​, providing a ​​stable and ultra-precise platform​​ for high-speed, large-format operations.
The ​​brand-new electric Z-axis​​ features ​​4 high-precision bearings​​ and undergoes ​​rigorous assembly testing​​.

All motion system fasteners are made from ​​high-precision CNC components​​, enabling ​​smooth, ripple-free operation at 1000mm/s​​—even under heavy loads—with ​​exceptional repeatability and positioning accuracy​​.

The ​​NEJE Max 4 V2​​ is engineered to achieve ​​1000mm/s acceleration​​ (with a design target of ​​100,000mm/s²​​ for both X and Y axes), ensuring ​​smooth and stable motion​​ across all axes through ​​precise CNC craftsmanship​​ and ​​optimized structural design​​.

Thanks to its ​​ultra-lightweight yet rigid frame​​, ​​intelligent power distribution​​, and ​​all-directional (X/Y/Z) smooth-motion architecture​​, the machine maintains ​​exceptional stability​​ even at high speeds.

Additionally, the ​​upgraded extended components​​ feature ​​reinforced stability structures​​, guaranteeing ​​consistent performance​​—even when operating at ​​larger working areas​​.

The ​​NEJE Max 4 V2 control board features an independent A-axis​​, allowing it to function as a dedicated rotary axis.

First, I'd like to clarify a common misconception: while the ​​A-axis serves as an independent control interface​​, you can also configure the ​​Y-axis or Z-axis as rotary axes​​ using LightBurn software.

However, this approach is relatively cumbersome compared to the simplicity and ease of use provided by the dedicated ​​A-axis module​​.

NEJE offers two rotary axis solutions:​​NEJE R5​​ (standard version)​​NEJE R6​​ (premium version for users requiring):
Larger diameter workpieces
Tilted surface processing
Higher operational efficiency
The ​​A-axis module is exceptionally user-friendly​​, controllable via both:​​
NEJE proprietary software​​ (pre-configured with hardware parameters - simply connect and input your workpiece diameter)​​
LightBurn software​​ (requires one firmware parameter configuration to match stepper motor precision scaling):
Note: ​​NEJE 5 and NEJE R6 have different precision scaling capabilities​​
After configuration, standard software functions become available​​Key
Benefits of NEJE Max 4 V2:​​​​
Default firmware is pre-optimized for NEJE R6​​ - ready to use immediately upon receipt​​Updated 1.5m cable​​ - installs directly without disassembly
​​GRBL native A-axis bugs have been fixed​​ by the NEJE team​​Full G-code compatibility​​ - control the A-axis just like X/Y/Z axes using standard commands (e.g., G0 for homing/reset)

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.（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 provides an external frame, which not only can collect exhaust gas and fire protection functions, but also can install cameras when the area is expanded.

The brand-new Max4 V2 control system is available for purchase on the website. This system is compatible with the Max4 version. After installation, you need to adjust the parameters to match the hardware performance.

The later versions of Max4 and the Max4 V2 control board share the same functions. Both are equipped with a contactless reset system. If you notice that the reset button has been removed from your mainboard, it means you have the latest version of the control board.

For more detailed information, please follow the NEJE Blog and Wiki. We will provide more in-depth explanations regarding the operation of the mainboard.

NEJE currently offers two specifications of electric axes that users can utilize for DIY projects. Additionally, these can be combined with independent control boards to create customized 3D motion frameworks according to individual preferences.

If you're accustomed to operating the NEJE software, you can directly modify the firmware parameters in the software settings.

If you're using LightBurn software, you'll need to modify the firmware parameters: set the values to 130and131 in LightBurn.

Additionally, you need to adjust the area parameters in both the ​​Device Settings​​ and ​​Device Configuration​​ menu options.

At present, the air assist of laser modules is divided into needle tube type and built-in type. The needle tube type helps to increase the outlet pressure, and it is recommended to use AOC air pump as lens protection (because the gas is oil-free and water-free)+high-pressure air pump greater than 30PSI. The needle tube type and built-in air assist are used together, which will reduce maintenance times or even avoid maintenance for the lens. If an air pump with a pressure greater than 30PSI is used separately, The built-in air assist requires the use of a clean air source with an oil-water filtration device, and a high-pressure air pump helps improve cutting efficiency

​​Emergency Stop Function Behavior Across Different Software:​​The emergency stop function is defined differently across various software platforms:​​NEJE Software & LaserGRBL Software​​: These software solutions strictly adhere to the original emergency stop functionality If the emergency stop is triggered during operation: The system will stop immediately To resume work, simply click the resume option within the software​​LightBurn Software​​: When the emergency stop is activated during operation: The project will be stopped The system will NOT automatically resume - manual intervention is required to restart​​Additional Safety Feature of NEJE Max 4​​: The device is equipped with built-in sensor protection If vibration is detected, the system will automatically pause operation This serves as an additional risk control mechanism

Remove the inner protective lens and check if both layers of lenses are clean.

Curved surface carving is a relatively professional CNC function, as it requires you to first create a 3D path file using CAM software. You can execute it through NEJE or lightburn software.

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.
