LightBurn 2.2.00 RC5 Pro (Smart Pattern & 3D Guide)

Overview of the Software

LightBurn is a comprehensive laser control and design application developed by LightBurn Software, a company based in the United States. Unlike many manufacturer-supplied tools, LightBurn is hardware-agnostic, supporting hundreds of laser machines from dozens of manufacturers across diode, CO2, fiber, UV, and galvo platforms.

The software combines three core functions in a single interface: vector design and editing, job planning and layer management, and direct machine control. This integration eliminates the need to switch between separate CAD, graphics, and controller applications during a typical workflow.

LightBurn 2.2.00 RC5 is distributed as a Release Candidate (RC), meaning it is an Early Access build intended for testing and feedback before the stable 2.2.0 release. RC builds can be installed side-by-side with the latest official release, so trying the new features will not overwrite your existing settings or project files.

The Pro tier ($199 USD, one-time purchase) unlocks support for DSP and galvo laser controllers, including Ruida, Trocen, TopWisdom, EZCad2, and BSL systems, along with the new Pro-exclusive True Nest feature.

Key Features

LightBurn 2.2.00 RC5 includes a rich feature set that spans design, layout, and machine control. Below are the capabilities most relevant to pattern-making and production workflows.

Design and Vector Editing

• Import artwork in AI, PDF, SVG, DXF, HPGL, PLT, PNG, JPG, GIF, BMP, and other common formats.

• Boolean operations, offset generation, welding, node editing, and vector repair tools for precise path manipulation.

• Shape creation tools including rectangles, ellipses, polygons, QR codes, and text with font control.

• Automatic and manual guide lines for alignment and spacing across complex layouts.

Layer and Job Management

• Assign cut, engrave, and mark operations to individual layers with independent speed, power, and pass settings.

• Material Test Generator and Interval Test Tool for calibrating settings across different materials.

• Grid Array and Circular Array tools for rapid duplication of patterns.

• Tool Layers that never output to the laser, useful for positioning and reference geometry.

New in 2.2: True Nest (Pro-Only)

True Nest is a full nesting solution built directly into LightBurn. Unlike the Quick Nest feature introduced in version 2.1, which nests based on bounding boxes, True Nest positions objects according to their actual contours. Four optimization levels let you balance computation time against layout quality, though all levels are described as “shockingly fast” compared to manual nesting. For production environments cutting repeated patterns from sheet material, True Nest can meaningfully reduce waste and material costs.

New in 2.2: Center Line Trace

The Center Line Trace option added to the Trace Image tool produces lines that run along the medial axis of shapes in a raster image. This is particularly effective for converting logos, hand-drawn sketches, and text into cuttable vector paths. For best results, use high-resolution source images with clear outlines; low-resolution inputs can generate extraneous offshoots where the medial axis calculation diverges from visual expectation.

New in 2.2: 3D Model Import and Depth Maps

LightBurn 2.2.00 RC5 introduces the ability to import 3D model files and generate depth maps from them. This opens workflows for relief engraving and textured surface marking that previously required external software to prepare.

New in 2.2: Multi-Page Projects

Multi-page projects allow a single .lbrn2 file to contain multiple pages, each with its own layout and layer configuration. This is useful for organizing complex jobs, managing templates for repeated customer orders, and keeping related designs together without relying on scattered workspace margins.

Additional 2.2 Enhancements

• PCB and Gerber file import support for electronics prototyping workflows.

• Local and network-available REST API for inter-application communication and automation.

• Galvo Move panel as a dockable widget for fiber and galvo laser users.

• LiDAR surface scanning with height-compensated engraving for uneven materials.

• Native ARM builds for macOS, improving performance on Apple Silicon computers.

What’s New in the Latest Version (2.2.00 RC5)

The RC5 build continues the refinement cycle that began with RC1 and RC2. While the headline features of the 2.2 series were introduced in earlier RCs, RC5 incorporates incremental bug fixes and stability improvements across the codebase.

Key changes since the initial 2.2 Early Access announcement include:

• Fixes for REST API job progress reporting.

• Corrections to Z-axis homing and limit switch behavior in device settings.

• Improved frame preview accuracy for split marking and rotary jobs.

• Camera overlay updates for negative-W alignment matrices.

• General stability fixes for save operations and viewport rendering.

As an RC build, 2.2.00 RC5 is not the final stable release. Users should expect that some features may change before the official 2.2.0 launch and should report issues through the LightBurn support forum or email.

System Requirements

LightBurn 2.2.00 RC5 is a 64-bit application. The following table summarizes the recommended and minimum hardware configurations for running the software effectively.

Important platform notes: Linux support ended with LightBurn 1.7. Users on Ubuntu or other Linux distributions should remain on version 1.7.08 or earlier. macOS 11 support also ends with the 2.x series; users on macOS 11 should download LightBurn 2.0.05. A dedicated GPU is not required, but OpenGL 3.3 or higher is recommended for smooth rendering of complex vector artwork.

Installation Guide

Installing LightBurn 2.2.00 RC5 is straightforward on Windows and macOS. The process below covers a typical Windows installation; macOS steps are analogous.

Step 1: Download the Installer

Download the RC5 build from the official LightBurn release repository. Early Access builds are available at release.lightburnsoftware.com. Ensure you select the 64-bit version for your operating system.

Step 2: Run the Installer

Double-click the downloaded executable file. Windows may display a SmartScreen warning because LightBurn is not currently digitally signed. Click “More info” and then “Run anyway” to proceed.

Step 3: Follow the Setup Wizard

• Select whether to create a desktop icon.

• Click “Install” to begin the installation process.

• When the installer completes, you will see options to install drivers and view the change log.

Step 4: Install Laser Drivers (Optional)

If you are connecting a laser via USB, the installer can place the necessary drivers on your system. For network-connected lasers or galvo controllers with proprietary drivers, follow the manufacturer’s instructions.

Step 5: Launch and Activate

Open LightBurn from the Start menu or desktop shortcut. New users receive a 30-day free trial with no feature restrictions. After the trial, a Core or Pro license key is required. Core licenses cost $99 USD, and Pro licenses cost $199 USD, both as one-time purchases that include one year of updates.

Side-by-side installation: Early Access builds install to a separate directory, so you can keep your stable LightBurn installation intact and switch between versions as needed.

How to Use the Software

LightBurn’s interface is organized around a central workspace, with toolbars and panels positioned for quick access to common functions. The workflow below outlines a typical pattern-making project using the new 2.2 features.

Step 1: Set Up Your Laser Device

Before starting a project, configure your laser in LightBurn. Go to the Laser Window (bottom-right by default) and select “Devices” to add your machine. LightBurn includes profiles for many common laser controllers; if your exact model is not listed, select a compatible profile or use a custom GCode configuration.

Step 2: Import or Create Your Design

Use File → Import to bring in vector artwork (SVG, DXF, AI, PDF) or raster images (PNG, JPG, BMP). Alternatively, create shapes directly in LightBurn using the drawing tools. For pattern work, start with a single element that you can then nest or array.

Step 3: Arrange Your Patterns with True Nest (Pro)

Select the objects you want to nest and open the True Nest dialog. Choose one of the four optimization levels. Higher levels spend more time searching for tighter layouts. Preview the result in the workspace and adjust the sheet dimensions if needed. True Nest respects the actual contours of each object, so irregularly shaped parts can be packed much more efficiently than with bounding-box nesting.

Step 4: Assign Layers and Cut Settings

Each color in the LightBurn color palette represents a layer. Double-click a layer to open the Cut Settings Editor and configure:

• Mode: Line, Fill, Offset Fill, or Image

• Speed: Movement rate in mm/s or mm/min

• Power: Percentage of laser power

• Passes: Number of repetitions

• Scan angle and interval for fill operations

Use the Material Test Generator under the Laser Tools menu to create a test grid on scrap material and determine optimal settings for your specific laser and material.

Step 5: Frame and Preview

Use the Frame button to trace the boundary of your job on the material without firing the laser. Press Alt+P to open the Preview window, which simulates the exact path the laser will take, including travel moves and layer order.

Step 6: Send the Job

Once framing and preview confirm correct positioning, click Start to send the job to the laser. Hold Shift while clicking Start to begin the job immediately.

Step 7: Use Multi-Page Projects for Organization

For complex jobs with multiple parts or customer orders, create additional pages within the same .lbrn2 file. Each page maintains its own layer settings and layout, making it easy to manage related patterns without opening multiple files.

Best Use Cases

LightBurn 2.2.00 RC5 is designed for a broad range of laser workflows. The following use cases highlight where the new features deliver the most value.

Production Pattern Cutting

Shops that cut repeated parts from sheet material—acrylic signage, wooden components, leather goods—benefit most from True Nest. By packing parts based on actual contours, material yield improves, and fewer sheets are consumed per batch.

Logo and Sketch Conversion

Center Line Trace excels at converting scanned logos, hand-drawn sketches, and text into single-line vector paths suitable for scoring, engraving, or cutting. This is valuable for personalization businesses and artists who work with hand-drawn designs.

Multi-Material Testing and Calibration

The Material Test Generator and Interval Test Tool help users systematically determine the best speed and power settings for new materials. This is essential for shops that regularly work with unfamiliar substrates.

Rotary and Cylindrical Engraving

LightBurn supports rotary attachments for engraving on tumblers, rings, and other cylindrical objects. Version 2.2 includes enhancements such as rotary framing for galvo lasers and improved external axis support.

Galvo Fiber Marking

With a Pro license, LightBurn controls EZCad2 and BSL galvo controllers, enabling fiber laser marking on metals and plastics. The new Galvo Move panel and Z-axis height setup for galvo controllers streamline setup for these machines.

Relief Engraving from 3D Models

The 3D model import and depth map generation features allow users to bring in STL or similar files and produce grayscale depth maps for variable-depth engraving, adding texture and dimensionality to wood, leather, and acrylic projects.

Advantages and Limitations

Advantages

• Unified workflow: Design, layout, and machine control in one application reduces software switching and file format conversion issues.

• Broad hardware compatibility: Supports GCode, DSP, and galvo controllers across hundreds of laser models.

• One-time purchase: Core and Pro licenses are perpetual; no subscription is required, though optional update renewals cost $40 per year.

• Active development: Regular releases introduce meaningful features and performance improvements.

• Strong community and documentation: Official documentation, a user forum, and extensive third-party tutorials support users at all skill levels.

Limitations

• Early Access stability: RC builds may contain bugs or incomplete features. Users should keep a stable installation for critical production work.

• Platform restrictions: Linux support ended with version 1.7; macOS 11 support ended with version 2.0.

• Learning curve: The interface is dense, and new users may take time to become proficient with layer management and device configuration.

• True Nest is Pro-only: Core license holders cannot access the full contour-based nesting feature, though a two-week Pro trial is available through License Management.

• Not a replacement for dedicated CAD: While LightBurn has capable vector editing tools, complex parametric design and drafting are better handled in applications like AutoCAD or Fusion 360.

Alternatives to the Software

LightBurn competes with several other laser control and design applications. The table below compares key characteristics of common alternatives.

LaserGRBL is a practical free option for compatible GRBL machines, but it lacks the depth of design tools and production features found in LightBurn. RDWorks is optimized for Ruida controllers but has a dated interface and limited cross-platform support. xTool Creative Space is an excellent choice for users within the xTool ecosystem but does not support third-party lasers.

For users who need advanced vector design alongside laser control, Adobe Illustrator or Inkscape can complement LightBurn by preparing artwork, which is then imported into LightBurn for layout and cutting.
