1.Wireless Connection via NEJE Bridge​

Users establish a virtual serial port connection between LightBurn and NEJE devices through the NEJE "Bridge" feature, enabling seamless wireless communication.

2.Bulk Data Transfer with REC Mode​

The "REC" function enables one-time full-package transmission of laser job data to the device, eliminating real-time dependency on LightBurn.

​​3.Offline Execution Capability​

Once the NEJE firmware completes data reception, users can disconnect from LightBurn and operate the device independently for uninterrupted job execution. This end-to-end solution removes USB cable constraints, prevents transmission interruptions during complex jobs, and ensures reliable offline operation – a significant upgrade over traditional real-time streaming workflows.

NEJE devices support the “REC” reception function for Lightburn and laserGRBL software, receiving all data before starting work, thus no longer occupying the computer.

A powerful, professional-grade freeware characterized by its wireless high-efficiency connectivity. Since 2013, NEJE software has undergone countless iterations, delivering exceptionally convenient user experiences for both beginners and advanced users.

The software features a ​​cloud-based material library​​ containing thousands of assets across categories including ​​images, vectors, geometries, artworks, architectures, and greeting cards​​. Users can effortlessly create projects like building with LEGO blocks.

NEJE Win Software delivers ​​unparalleled wireless control capabilities​​ - supporting not only USB connections but also ​​BLE (Bluetooth Low Energy) mode​​, enabling direct wireless device pairing straight from the Windows PC.

As a versatile ​​wireless expansion solution​​ for third-party software, NEJE Win transforms into a "Bridge" that provides virtual COM ports for ​​LightBurn​​ and ​​LaserGRBL​​, enabling secure wireless control. Through continuous optimization, NEJE has implemented advanced anti-packet-loss algorithms and data stabilization protocols.

Particularly noteworthy is the integration with NEJE's proprietary ​​"REC" firmware feature​​:

Users can now ​​directly transmit complete project files from LightBurn to the device​​

Initiate operations ​​without requiring constant software-device binding​​This revolutionary approach eliminates traditional workflow limitations, significantly enhancing both reliability and operational efficiency.

Step1: Add Custom Button

Step2: Start a offline work

The NEJE Bridge function enables wireless and stable connectivity between LightBurn/laserGRBL and NEJE devices. After files are transferred to the device via LightBurn/laserGRBL's "REC" mode, users can: ​​

Disconnect Bridge​​ (optional):
Use the device's multifunction button to start jobs directly.
​​
Keep Bridge Connected​​ (alternative):
Maintain software control for positioning and job initiation.

Note: No active data transmission occurs during job execution.

Users may close the computer or disconnect after job initiation. ​​

USB Connection Workflow​​:
When using USB, jobs can be initiated immediately after "REC" completes file transfer – the computer and USB cable can then be safely disconnected.

NEJE devices enable ultra-fast transmission of vector files (excluding high-resolution raster images that require significant bandwidth). With proprietary data-loss prevention technology, our wireless transfer is more reliable than USB connections and eliminates computer resource occupation.

The ​​'REC' mode​​ operates by fully preloading files into the device before processing – a departure from LightBurn's real-time data streaming. This approach not only frees up computer resources but also ensures unmatched reliability by eliminating USB transfer instability.

Low-Light Positioning 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.

How to set low light intensity in GRBL？

“Grbl Configuration”- Write any value from 0.08 - 0.5, The value means % laser intensity, please proceed with caution,If you modify the parameters and cannot restore the default firmware, you can re-update the firmware in NEJE Win software.

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.

Under ​​LaserGRBL​​ and ​​NEJE Win​​ software control:

Pressing the emergency stop button pauses the ongoing operation.Resuming work requires clicking the software's resume command after releasing the button.

For ​​LightBurn​​ software:
The emergency stop definition does ​​not​​ follow standard GRBL protocol.When controlling devices via ​​USB real-time data streaming​​ (LightBurn's default mode), pressing the emergency stop button ​​immediately terminates​​ the current project.​​Partially completed work cannot be resumed​​ – this behavior differs significantly from LaserGRBL/NEJE's pause-and-resume logic.​​
Critical Note:​​
Users must distinguish between these two emergency stop implementations to avoid unintended workflow interruptions.

The NEJE Win software includes a firmware update option after login.

The NEJE software will continue to provide free OTA firmware and software upgrade services to users worldwide, with more practical features and reliable performance to support your creations and manufacturing. When you receive a new device, it is recommended that you first connect the USB cable, open the NEJE Win software, and check for the latest firmware updates.
