The LONGER Ray5 and LONGER B1 laser engravers are capable of engraving and cutting a wide range of materials with high precision and efficiency. However, achieving optimal results requires careful adjustment of processing parameters—particularly laser power and engraving speed, as different materials respond uniquely to laser energy.

Understanding Material Response to Laser Settings

Materials react differently when exposed to laser energy. For metals in particular, variations in power output and movement speed can significantly affect the engraving outcome.

By fine-tuning these parameters, users can achieve different surface oxidation levels and heat effects, which can produce subtle color variations on metal surfaces. This controlled thermal interaction is the foundation of multicolor laser engraving on metal, a technique widely used in decorative and industrial applications.

Both the LONGER Ray5 (5W) and LONGER B1 are capable of metal engraving. However, the B1 offers superior stability and higher power capability, making it more suitable for advanced applications such as multicolor metal engraving.

Using LaserGRBL for Parameter Optimization

To achieve precise and repeatable results, LaserGRBL provides a built-in tool called Power vs Speed Test, which allows users to quickly identify optimal engraving parameters for specific materials.

Step 1: Access the Power vs Speed Test Tool

From the LaserGRBL main interface:

Select:

Generate → Power vs Speed Test

This will open the parameter configuration window.

Step 2: Configure Power Settings

LaserGRBL uses a scaled power system:

• S-10 = 1% power
• S-1000 = 100% power

For testing purposes, it is recommended to define a power range such as:

• Minimum: 100
• Maximum: 1000
• Step size: 10

This allows fine-grained control over laser output for accurate material testing.

Step 3: Configure Speed Settings

Next, define engraving speed based on material type:

• Wood: approximately 3000–9000 mm/min
• Metal & steel: approximately 100–1500 mm/min

A recommended configuration is to use 7 steps for balanced testing coverage.

Step 4: Set Line Density (Quality)

The engraving resolution can be adjusted using line density settings:

• Recommended range: 8000–12000 lines/mm

Higher values result in finer detail but longer processing time.

Step 5: Generate the Test File

After configuring parameters, click:

“Create!”

LaserGRBL will generate a test pattern combining multiple power and speed combinations for evaluation.

Step 6: Export and Run the Test

To proceed:

1. Select File → Save (Advanced Option)
2. Export the generated file as G-code
3. Transfer it to a microSD card or device storage
4. Run the test on the LONGER Ray5 or B1

Alternatively, the test can also be executed directly via USB connection using the Cutting Test mode, if preferred.

Step 7: Analyze Results and Optimize Settings

After completion, carefully inspect the engraved test pattern. The variations in tone, depth, and clarity will help determine the most suitable combination of power and speed for your specific material and desired effect.

This calibration process is essential for achieving consistent high-quality results, especially in advanced applications such as metal marking and multicolor engraving.

Conclusion

By leveraging the Power vs Speed Test in LaserGRBL, users of the LONGER Ray5 and B1 can efficiently identify optimal engraving parameters for different materials. While both machines are capable of metal engraving, the B1 provides enhanced performance and stability, making it the preferred choice for precision-driven and multicolor metal engraving applications.

Laser engraving is emerging as a state-of-the-art technology acclaimed for its efficacy in protecting and popularizing cultural heritage. Its accuracy, versatility, and non-contact nature make it ideal for restoring historical pieces and preserving cultural artifacts. This article explores how the Laser B1 30W can aid in the preservation of culture through practical applications.

Introduction

Laser engraving uses a focused laser beam to etch, engrave, or cut materials with precision. This technology is particularly useful in cultural heritage conservation, as it can interact delicately with surfaces without causing damage. For example, laser scanning and engraving can create precise replicas of deteriorated stone carvings in medieval cathedrals, while laser ablation techniques can remove layers of dirt and grime from ancient pottery without harming the original material.

 

Historical buildings and structures, such as ancient temples, palaces, castles, and fortresses, can benefit greatly from laser engraving. The Laser B1 30W, with its working area of 450x440mm (17.72x17.32 inches) and a laser spot size of 0.08x0.15mm, allows for the creation of detailed designs and patterns on walls, pillars, and ceilings. This not only enhances the aesthetic value of the structures but also helps in preserving their cultural significance. Additionally, laser-engraved plaques and signs can provide historical context and background information for visitors.

Artifacts and relics, including ancient sculptures and statues, can be restored or enhanced using laser engraving. The Laser B1 30W, with its optical output power of 30W and ability to cut up to 25mm plywood and 50mm acrylic in one pass, is perfect for replicating missing pieces or restoring damaged parts of sculptures. This helps in studying and appreciating these artifacts in their original form.

 

Historical monuments and memorials, such as war memorials and historical markers, also benefit from laser engraving. Memorial plaques or walls can be created using this technology to etch the names of soldiers or significant historical events. The durability and precision of laser engraving ensure that the information remains clear and legible for generations.

Preservation of Historical Architectural Details:

Laser engraving is used to mark hard-to-carve architectural designs on ancient buildings. For instance, in restoring a medieval cathedral in Europe, laser scanners and engravers were employed to recreate worn-out stone carvings.

 

Conservation of Ancient Artifacts:

Laser ablation cleaning techniques are less intrusive and effective for cleaning and restoring fragile items from antiquity. They remove layers of deposits without damaging the original material, enhancing the appearance of the artifacts.

 

Customization of Souvenirs:

Laser engraving adds value to souvenirs by creating personalized designs on keychains, mugs, or miniature pieces of art. The speed of the Laser B1 30W, with a fastest working speed of 36000mm/min, allows for quick execution, letting tourists take home customized souvenirs.

 

Interactive Exhibits:

Laser-engraved QR codes on exhibits can provide visitors with access to additional information, videos, or audio clips via their smartphones. Laser engraving can also create textured maps or braille descriptions for visually impaired visitors, enhancing their experience.
