Why Creating QR Codes in LightBurn Matters

QR codes are widely used in modern engraving applications because they allow users to instantly access digital information by scanning with a smartphone.

Laser engraved QR codes are useful for:

• Product branding
• Business cards
• Equipment labels
• Website links
• Wi-Fi sharing
• Digital menus
• Inventory tracking
• Social media promotion

Using LightBurn to generate QR codes simplifies the workflow because you can create, edit, resize, and engrave the code directly inside the software without needing third-party design tools.

If you are new to laser engraving workflows, you may also find it helpful to review the official LightBurn software documentation and explore additional tutorials from LONGER Laser Academy.

Before You Start

Requirements

Before creating a QR code in LightBurn, prepare the following:

Hardware

• A compatible LONGER laser engraver
• Properly connected computer
• Stable work surface
• Compatible engraving material

Software

• LightBurn software installed
• Correct machine profile configured

Additional Preparation

• Smartphone for QR code testing
• Proper focus adjustment
• Clean material surface

For machine setup guidance, follow the official LONGER support resources.

Precautions

Before engraving a QR code with a laser engraver, keep these safety and preparation tips in mind:

• Always wear appropriate laser safety glasses.
• Ensure proper ventilation during engraving.
• Do not engrave reflective or unsafe materials.
• Make sure the material is flat and securely positioned.
• Verify focus accuracy before engraving.
• Test small QR codes before large production runs.
• Avoid making QR codes too small to scan.

Follow official machine specifications or instructions.

Step-by-Step Tutorial

Step 1: Open LightBurn

Action

Launch the LightBurn software on your computer and connect your LONGER laser engraver.

Expected Result

The LightBurn workspace should open successfully, and the machine connection should appear correctly.

Important Notes

• Verify that the correct machine profile is selected.
• Confirm communication between the computer and laser engraver before continuing.
• If connection problems occur, restart the software and reconnect the machine.

If you need additional setup guidance, review the LightBurn setup guide.

Step 2: Create a QR Code

Action

Use the QR Code creation feature inside LightBurn to generate a new QR code.

Expected Result

A QR code object should appear in the LightBurn workspace.

Important Notes

• The QR code is generated directly inside the software.
• You can later resize or reposition the QR code as needed.
• Avoid modifying the QR code shape manually, as this may reduce scan reliability.

Step 3: Enter QR Code Content

Action

Input the information you want the QR code to contain.

Examples include:

• Website URLs
• Text
• Contact information
• Wi-Fi credentials
• Product serial numbers

Expected Result

The QR code updates automatically based on the entered content.

Important Notes

• Longer URLs create denser QR codes.
• Dense QR codes may require larger engraving sizes for reliable scanning.
• Keep content concise whenever possible.

For branding workflows, many users combine QR codes with logos or product graphics. You can learn more about image preparation in the LONGER image engraving tutorials.

Step 4: Adjust QR Code Size

Action

Resize the QR code inside the LightBurn workspace according to your engraving project requirements.

Expected Result

The QR code appears at the desired dimensions on the workspace.

Important Notes

• Extremely small QR codes may fail to scan.
• Larger QR codes generally produce better scanning performance.
• Maintain proportional scaling to avoid distortion.

When resizing:

• Use consistent scaling
• Avoid stretching horizontally or vertically
• Keep edges sharp and clean

If unsure about minimum engraving size, follow official machine specifications or instructions.

Step 5: Position the QR Code

Action

Move the QR code to the correct location within your project layout.

Expected Result

The QR code is properly aligned on the material workspace.

Important Notes

• Leave enough spacing around the QR code.
• Avoid placing detailed graphics too close to the code.
• Ensure the QR code fits fully inside the engraving area.

Good positioning improves readability and scanning reliability.

Step 6: Configure Engraving Settings

Action

Set the engraving parameters in LightBurn according to your material and laser machine.

Expected Result

The QR code layer is ready for engraving.

Important Notes

• Use engraving settings appropriate for the material type.
• Incorrect power or speed may reduce contrast and scanning quality.
• Test settings on scrap material first when possible.

Typical considerations include:

• Laser power
• Engraving speed
• Line interval
• Pass count

Follow official machine specifications or instructions.

For material-specific setup recommendations, explore the LONGER material parameter guides.

Step 7: Preview the Engraving

Action

Run the LightBurn preview function before starting the laser job.

Expected Result

You should see a simulation of the engraving process.

Important Notes

Previewing helps identify:

• Incorrect positioning
• Oversized designs
• Missing elements
• Unexpected engraving paths

Always preview before engraving to reduce material waste and avoid mistakes.

Step 8: Start the QR Code Engraving

Action

Start the engraving process using your LONGER laser engraver.

Expected Result

The laser engraves the QR code onto the selected material.

Important Notes

• Monitor the engraving process continuously.
• Do not leave the laser engraver unattended.
• After engraving, test the QR code using a smartphone scanner.

A successful QR code should scan quickly and consistently under normal lighting conditions.

Common Problems and Solutions

Tips for Better QR Code Engraving Results

Use High Contrast Materials

QR codes scan more reliably when there is strong contrast between engraved and non-engraved areas.

Examples include:

• Dark engraving on light wood
• White marking on dark anodized aluminum
• Black engraving on coated surfaces

Avoid Extremely Small QR Codes

Tiny QR codes often become unreadable after engraving due to laser spot size limitations.

Test scanning performance before final production.

Keep the QR Code Simple

Shorter content creates cleaner QR code patterns that are easier to engrave and scan.

Whenever possible:

• Use shortened URLs
• Avoid unnecessary characters
• Keep text concise

Clean the Surface After Engraving

Dust, smoke residue, or burn marks can interfere with smartphone scanning.

Use a soft cloth to clean the engraved area carefully after completion.

Test With Multiple Devices

Different smartphone cameras may scan differently.

Verify the QR code using:

• iPhone cameras
• Android cameras
• QR scanner apps

This helps confirm compatibility across devices.
