Introduction

To improve editing efficiency and operational safety, the software provides two core features: Combine/split and layer lock/unlock.

The Combine/Split function allows multiple independent objects to be temporarily grouped into a single entity for unified operations or separated back into their original objects when needed. This is primarily used for batch transformations such as moving, scaling, and alignment.

The Layer Lock/Unlock function prevents accidental selection, modification, or deletion of objects on a specific layer while keeping the layer visible. It is typically used to protect completed backgrounds or reference content.

Both features use clear icons, explicit command names, and state-based dynamic interactions to ensure predictable behavior and reduce user error, especially in complex editing scenarios.

Function 1: Combine/Split

The purpose of this function is to temporarily bind multiple independent objects into a whole for operation or to disassemble the whole back into independent objects.

1. Icon and Text Design

• Combined icons: Icons that use two or more geometric shapes connected together.

• Split icons: Icons that use a graphic made up of multiple parts, with a clear visual cue of separation.

2. Directly use "Group" and "Split."

• Group: Combines selected objects into a single unit, making them easier to move and transform simultaneously.

• Split: Splits a grouped object into its original, independent objects.

3. Dynamic and Interactive Feedback

• Top-left menu: Right-click on a selected object to dynamically display menu items based on the selected object's status.

  • When multiple independent objects are selected, the menu displays "Combine."

  • When a grouped object is selected, the menu displays "Split."

• Changes after executing the command:

  • After executing "Combine," the control points of the selected objects disappear and are replaced by a unified control box.

  • After executing "Split," the unified control box disappears, and each sub-object's control points reappear.

• New User Guide: When the software is first launched or when entering the drawing module, a brief reminder card indicates that multiple objects can be "combined" for easier unified management.

Function 2: Layer Lock/Unlock

This feature prevents any accidental editing (selection, moving, deletion) of all objects on a specific layer while still maintaining their visibility and is commonly used to protect completed backgrounds or reference drawings.

1. Icon and Text Design

• Lock icon: Uses the classic closed lock icon. This is the universal lock/unlock symbol.

• Unlock icon: Uses the open lock icon.

2. Button/Menu Text

• Lock Layer: Locks the layer, preventing its contents from being selected or modified.

• Unlock Layer: Unlocks the layer, allowing its contents to be edited.

3. Dynamic and Interactive Feedback

• On-canvas behavior limitations: When a user attempts to click, select, or drag an object on a locked layer, no action is taken.

Using LightBurn layers is one of the easiest ways to perform engraving and cutting on wood in a single workflow. By assigning different settings to separate layers, you can engrave details first and then cut the final shape automatically without manually restarting the job. This method improves efficiency, keeps alignment accurate, and simplifies laser project management for beginners and experienced users alike.

What This Guide Covers

This guide explains how to simultaneously engrave and cut on wood using LightBurn layers. You will learn how to:

• Separate engraving and cutting operations into different layers
• Assign different laser parameters to each layer
• Process both operations sequentially in one job
• Improve workflow efficiency and project accuracy

Quick Answer

To engrave and cut wood at the same time in LightBurn:

1. Create separate layers for engraving and cutting
2. Assign different colors to each layer
3. Use low power and fast speed for engraving
4. Use high power and slow speed for cutting
5. Run the job so LightBurn processes each layer sequentially

This allows both operations to complete automatically in a single workflow.

Why This Process Matters

Using LightBurn layers for engraving and cutting provides several important benefits:

• Keeps engraving and cutting settings organized
• Reduces manual setup time
• Maintains alignment accuracy between operations
• Allows complex projects to run automatically
• Improves workflow efficiency for wood projects

For wood signs, ornaments, keychains, decorative panels, and custom crafts, layer management is one of the most useful LightBurn features available.

Instead of running separate jobs for engraving and cutting, the laser machine completes both operations in the correct sequence during one session.

Before You Start

Before beginning, make sure your laser engraver is properly connected to LightBurn and fully calibrated.

Also ensure:

• The wood material is flat and securely placed
• The laser focus is correctly adjusted
• Proper ventilation is available
• The work area is free from flammable materials

Follow official machine specifications or instructions.

Requirements

You will need:

• A compatible laser engraver
• LightBurn software
• Wood material suitable for laser engraving and cutting
• A design containing engraving and cutting elements

The workflow applies to various LONGER laser engraver models including:

• Ray5 Series
• Nano Series
• B1 Series

Precautions

Before running the laser job, keep these safety precautions in mind:

• Never leave the laser machine unattended during operation
• Ensure proper airflow and smoke extraction
• Double-check power and speed settings before starting
• Verify that engraving layers run before cutting layers
• Test settings on scrap wood first when using unfamiliar materials

Incorrect layer order may cause the cut piece to shift before engraving is complete.

Step-by-Step Tutorial

Step 1: Separate Engraving and Cutting with Layers

Action

In LightBurn, create different layers for engraving and cutting. Each layer is represented by a different color, which helps organize the workflow.

For example:

• Use one color for engraving
• Use another color for cutting

Expected Result

Your design elements are separated into distinct layers that can each use independent processing settings.

Important Notes

Different colors in LightBurn represent different layers only for organization purposes. The color itself does not affect engraving performance.

A common example is:

• Blue layer for engraving
• Red layer for cutting

This makes it easier to visually identify each operation before starting the laser job.

Step 2: Assign Different Parameters for Each Layer

Action

Once the design is separated into layers, assign different laser parameters to each one.

For the engraving layer:

• Use low power
• Use fast speed

For the cutting layer:

• Use high power
• Use slow speed

Expected Result

The engraving layer produces surface details while the cutting layer cuts through the wood material.

Important Notes

Engraving and cutting require very different laser behavior:

Using separate layers prevents the need to manually adjust settings during the job.

If you are unsure about ideal settings for your material thickness or machine power, follow official machine specifications or instructions.

Step 3: Process Each Layer Sequentially

Action

Assign different colors to each layer so LightBurn can process them with their designated settings.

For example:

• Blue for engraving
• Red for cutting

Start the laser job after confirming the layer setup.

Expected Result

LightBurn automatically processes each layer sequentially using the assigned parameters.

The engraving operation completes first, followed by the cutting operation.

Important Notes

Layer order is important. In most workflows:

1. Engraving should happen first
2. Cutting should happen last

This helps prevent material movement after the part is cut free from the wood sheet.

You can use the Preview function in LightBurn to confirm the operation sequence before starting the machine.

Understanding How LightBurn Layers Work

LightBurn layers function like separate instruction groups within the same project.

Each layer can contain its own:

• Speed
• Power
• Pass count
• Tool mode
• Processing order

This makes it possible to combine multiple operations into one file without reconfiguring the machine between steps.

Typical examples include:

• Image engraving
• Text engraving
• Vector outlines
• Contour cutting

Advanced projects may contain several engraving layers plus one final cutting layer.

Recommended Workflow Order

For most wood projects, the recommended processing order is:

1. Internal engraving
2. Fine detail engraving
3. Border engraving
4. Final contour cutting

This workflow improves stability and helps maintain alignment accuracy.

Common Problems and Solutions

Tips for Better Results

Use Clear Layer Colors

Assign highly visible colors to different operations. This makes it easier to identify engraving and cutting paths quickly.

Preview Before Running

Always use the Preview function in LightBurn before starting the machine. This helps verify:

• Layer order
• Alignment
• Engraving paths
• Cutting paths

Test on Scrap Material

Wood species and thickness can affect laser performance significantly.

Before running a final project:

• Test engraving quality
• Verify cutting depth
• Check edge quality

Keep Cutting Last

Final contour cutting should normally occur after all engraving operations are complete.

This reduces the chance of movement or alignment issues.

Organize Complex Projects

For advanced projects, consider naming layers clearly, such as:

• Photo Engraving
• Text Engraving
• Border Cut
• Final Cut

This improves workflow organization and troubleshooting.

Window > Cuts/Layers

This will restore the layer management panel.

Final Thoughts

Using LightBurn layers to simultaneously engrave and cut on wood is an efficient and beginner-friendly workflow that simplifies laser project management. By separating operations into different layers, assigning independent settings, and processing them sequentially, you can complete detailed engraving and precision cutting in a single job.

This approach improves workflow efficiency, maintains alignment accuracy, and helps create cleaner, more professional laser projects with less manual intervention.

For best results, always verify layer order, preview the project before running, and follow official machine specifications or instructions.

Core Concept: What are LightBurn layers?

You can think of LightBurn layers as transparent acetate sheets. Each sheet contains different graphics (such as cutting lines, engravings, marking lines, etc.), and each sheet is assigned different processing parameters (power, speed, number of passes, etc.). Finally, stacking all the sheets together creates a complete artwork, and the laser processes each layer in the order you set.

1. Location and Interface of the Layer Panel

1.1 Finding the Layer Panel

On the right side of the software interface, find the "Cuts/Layers" panel. If it's not visible, click Window > Cuts/Layers from the top menu bar to make sure it's selected.

1.2 Understanding the Interface

1. Layer List: Displays the name, color, status, and parameter previews of all layers.

2. Eye Icon: Controls layer visibility. Click to hide/show a layer.

3. Lock Icon: Locks a layer. Once locked, no objects on that layer can be selected or edited.

4. Color Block: Represents the display color of all objects on that layer (for onscreen differentiation only, does not affect actual engraving).

5. Parameter Bar: Displays the default processing mode (e.g., cutting, scanning/engraving) and key parameters (power, speed) for that layer.

2. Basic Layer Management

2.1 Creating a New Layer

When you import a file, a layer will be added.

• It's recommended that you name the new layer, such as "Cut Layer," "Image Engraving," "Vector Engraving," or "Marker Layer." Giving your layer a descriptive name is a good practice!

2.2 Setting the Current Working Layer

• In the Layers panel, click the layer you want to draw on. This layer will highlight, indicating it's the active layer.

• From now on, all new shapes you create using the drawing tools will automatically be placed on this active layer.

2.3 Setting the Layer Color

• After selecting a layer, you can select a new display color for it in the lower-left corner. This helps you quickly distinguish different layers visually.

2.4 Hiding and Locking Layers

• Click the "eye" icon to hide a layer. Hidden layers won't be engraved, making them ideal for temporarily shutting down certain processes or keeping backups.

• Click the "lock" icon to lock a layer. This prevents accidental selection or modification, which is very useful for complex shapes.

2.5 Deleting a Layer

• Select a layer and press Delete on your keyboard to delete it.

• Note: Deleting a layer will also delete all objects on that layer.

3. Setting Processing Parameters for Different Layers

This is the essence of layer management—assigning independent laser parameters to each layer.

3.1 Selecting a Layer: In the Layers panel, simply click the layer for which you want to set parameters.

3.2 Setting Parameters: The toolbar at the top of the software or the "Cutting/Engraving" parameter panel on the right will display the parameters for the currently selected layer.

3.3 Tool: Select a processing method, such as Cutting, Scanning (Engraving), Filling, or Image.

3.4 Power/Speed/Times: Set the desired process for the layer. For example:

• Cutting layer: Tool = Cut, Power = 100%, Speed = 200 mm/min, Times = 1
• Vector Engraving layer: Tool = Scan (Engrave), Power = 50%, Speed = 6000 mm/min, Line Count = 0.06 mm
• Image Engraving layer: Tool = Image, Mode = Grayscale, Power = 60%, Speed = 6000 mm/min, Line Count = 0.06 mm

3.5 Parameter Inheritance: All objects created on this layer will use these default parameters. You can also select individual objects and adjust them, which will override the layer's default settings.

4. Controlling the Processing Order: Layer Order

The laser machine's default processing order is top to bottom.

4.1 Adjusting the layer order: In the Layers panel, simply drag layers to change their top-to-bottom order.

4.2 Best Practice Order (generally):

• First: Internal engraving/shallow engraving (such as image engraving or fine text engraving)
• Middle: External engraving/deep engraving (such as a vector engraving border)
• Last: Cutting (Ensure all engravings are complete before removing the part from the material to prevent shifting)

5. Practical Workflow Example: Creating an Engraved Keychain

Suppose you want to create a wooden keychain that includes engraving a photo and cutting the outer edges.

5.1 Planning:

• This requires two steps: photo engraving and contour cutting.

5.2 Creating Layers:

• Import the file and create a new layer, name it "Photo Engraving," and set the color to blue.

• Import it again and create a second layer, name it "Contour Cutting," and set the color to red.

5.3 Setting Parameters:

• Select the layer, set the tool to Engraving and Filling, and set the appropriate power and speed (e.g., 60% power, 6000 mm/min speed).

• Select the "Contour Cutting" layer, set the tool to Cutting, and set the cutting parameters (e.g., 100% power, 200 mm/min speed).

5.4 Assigning Objects:

• Make sure the "Photo Engraving" layer is the active layer.

• On the "Contour Cutting" layer, draw the outline of the keychain (e.g., a circle or a custom shape).

5.5 Adjusting the Order:

• In the Layers panel, make sure the "Photo Engraving" layer is above the "Contour Cutting" layer. This way, the laser will engrave the fill first, then cut.

5.6 Preview and Export:

• Use the Preview function (computer icon) to check the results and order. You should see the blue areas engraved first, followed by the red areas cut.

• Click Engrave Directly to Device, and LightBurn will automatically export all layer data to the laser in the correct order and parameters.

Engraving defects such as misalignment, distorted lines, and incomplete circles are common issues encountered during laser engraving. These problems are typically related to mechanical instability or improper motion control settings. This article outlines the root causes and provides practical solutions to restore engraving accuracy on Longer laser engravers.

1. Common Issues

Users may observe the following symptoms during operation:

• Engraved patterns appear offset or shifted
• Straight lines become wavy or uneven
• Circular shapes are not fully closed
• Repeated designs show inconsistent positioning

These issues indicate that the motion system is not operating with the required precision.

2. Mechanical Adjustment

2.1 Eccentric Nut Calibration

The eccentric nuts control the pressure between the rollers and the guide rails. Improper adjustment can lead to instability or excessive resistance.

If the nuts are too loose, the laser module may wobble during movement, causing misalignment. If they are too tight, movement becomes restricted and may introduce vibration.

Adjust the eccentric nuts so that the rollers maintain firm contact with the rails while still allowing smooth and consistent movement.

2.2 Timing Belt Tension

Timing belts play a critical role in motion accuracy. Insufficient tension can result in positioning errors and deformation of engraved shapes.

Check both X-axis and Y-axis belts and ensure they are properly tensioned. The belts should feel firm when pressed lightly, without noticeable slack. Avoid overtightening, as this may increase wear on motors and bearings.

2.3 Timing Pulley Alignment

Misaligned pulleys can cause the timing belt to rub against the pulley edges, leading to friction, noise, and unstable motion.

Ensure that the timing belts run parallel to the motion axis. Adjust the pulley position if necessary to eliminate lateral friction and ensure smooth transmission.

2.4 Fastener Inspection

Loose mechanical components are a major source of engraving inaccuracies.

Inspect and tighten all relevant screws and connections, including:

• X-axis timing pulley set screws
• Y-axis motor couplings
• Pulley mounting screws

All components should be securely fixed to prevent any movement during operation.

3. Software Optimization

Mechanical adjustments should be complemented by proper software configuration.

3.1 Overcut Setting in LightBurn

Incomplete circles or open paths are often caused by insufficient overlap between the start and end points of a path.

In LightBurn, the Overcut parameter can be used to extend the cutting path slightly beyond the endpoint.

Set the Overcut value to 0.3 mm in the Advanced settings. This ensures that closed shapes such as circles are fully completed without visible gaps.

4. Additional Recommendations

Regular maintenance is essential to maintain engraving accuracy over time.

• Keep guide rails clean and free of dust or debris
• Periodically check belt tension and component tightness
• Use appropriate speed and power settings for detailed work
• Perform routine calibration to ensure consistent performance

5. Conclusion

Engraving misalignment, warped lines, and incomplete circles are typically caused by mechanical looseness, improper belt tension, pulley misalignment, or incorrect software settings. By systematically inspecting and adjusting both hardware and software parameters, users can effectively eliminate these issues and achieve precise, high-quality engraving results with Longer laser engravers.

Line interval is a key setting in LightBurn that directly impacts engraving detail, visual quality, and processing time. This guide uses the LONGER NANO Pro to demonstrate how different line intervals—from 0.03mm for high-detail work to 0.12mm for fast, low-detail tasks—can dramatically change the outcome of your laser projects. By understanding and adjusting this parameter, users can achieve the perfect balance of precision, efficiency, and artistic style in their engravings.

LightBurn Framing Mode is essential for accurate laser engraving with Longer machines like Nano, B1, and Ray5. It lets users preview the engraving area before starting the job, minimizing material waste and errors. This guide walks you through enabling Framing Mode in LightBurn—just activate the laser fire button, set framing power to 2%, and you're ready to frame with precision. Perfect your setup and avoid costly mistakes with this simple yet crucial step in the engraving process.

Longer laser engravers like Ray5 and B1 series can create brilliant multicolor engravings on metal, starting from just 10W of power. Using LightBurn's Material Test, users can easily identify the best settings to unlock vibrant shades. Even with lower-power lasers, up to 90 distinct colors are possible, making metal engraving both creative and accessible. Learn how to test, tweak, and master color engraving with your Longer machine.

Proper cooling is critical for maintaining laser performance and preventing damage to your laser module. The Longer B1 cooling fan continuously removes heat generated during engraving and cutting operations. Over time, smoke and dust can accumulate inside the fan, reducing airflow and cooling efficiency. In some cases, prolonged use may cause the fan to stop working entirely, making cleaning or replacement necessary.
