The **Laser 2 Offset** setting in LightBurn allows you to align Laser 2's output with Laser 1 by compensating for the distance between the two laser heads. --- #### What is Laser 2 Offset? The **Laser 2 Offset** feature adjusts the X and Y fields in the Device Settings window to account for the physical distance between two laser heads. By specifying the offset values, the output from Laser 2 can align perfectly with Laser 1. --- #### Steps to Set Laser 2 Offset Follow these steps to measure the offset and apply the appropriate adjustments: --- 1. **Prepare Your Laser System**: - Load a large, expendable material into the laser bed, ensuring it is large enough for both laser heads to mark simultaneously. - Ensure the **Enable Laser 2 Controls** option is toggled on. ![Guide-SetLaser2Offset-OffsetOff](https://support.salasers.com/hs-fs/hubfs/Guide-SetLaser2Offset-OffsetOff.png?width=688&height=252&name=Guide-SetLaser2Offset-OffsetOff.png) 2. **Create and Mark Vertical Lines**: - Use the **Draw Lines** tool in LightBurn to create a short, perfectly vertical line. - Hold **Shift** while drawing to ensure the line is straight. - Assign the line to a layer set to **Line Mode** and enable both Laser 1 and Laser 2 in the Cut Settings Editor. ![Guide-SetLaser2Offset-BothLasersEnabled](https://support.salasers.com/hs-fs/hubfs/Guide-SetLaser2Offset-BothLasersEnabled.png?width=688&height=225&name=Guide-SetLaser2Offset-BothLasersEnabled.png) - Apply settings that will mark the material without cutting through. - Select **Current Position** as your **Start From** mode and press **Start** to mark the lines. 3. **Measure the Distance**: - Measure and record the distance between the lines marked by Laser 1 and Laser 2. ![Guide-SetLaser2Offset-VerticalLineMeasure](https://support.salasers.com/hs-fs/hubfs/Guide-SetLaser2Offset-VerticalLineMeasure.png?width=688&height=388&name=Guide-SetLaser2Offset-VerticalLineMeasure.png) 4. **Enable and Apply Laser 2 Offset**: - In the Device Settings window, enable **Laser 2 Offset**. - If Laser 2 is farther from the machine’s origin than Laser 1, enter the measured distance as a negative value in the X field. If closer, use a positive value. ![Guide-SetLaser2Offset-Enabled](https://support.salasers.com/hs-fs/hubfs/Guide-SetLaser2Offset-Enabled.png?width=688&height=241&name=Guide-SetLaser2Offset-Enabled.png) 5. **Adjust for Horizontal Lines**: - Rotate the vertical line 90 degrees to make it horizontal using the `.` key. - Add a sub-layer to the layer assigned to the horizontal line: - Enable Laser 2 for the second sub-layer while disabling Laser 1. - Apply settings for Laser 2 to mark the material. - Select **Current Position** and press **Start** to mark the lines. 6. **Verify and Fine-Tune Alignment**: - Check the alignment of the horizontal lines in the X dimension: - If misaligned in the opposite direction, reverse the sign of the X offset. - If misaligned in the correct direction, re-measure and refine your adjustments. 7. **Adjust for Y Offset** (if needed): - If the horizontal lines are aligned in X but not in Y, measure the misalignment. - Enter the measured Y offset in the Device Settings window, using a negative value if Laser 2 is farther from the origin or a positive value if closer. - Mark the horizontal lines again to confirm alignment. ![Guide-SetLaser2Offset-HorizontalLineMeasure](https://support.salasers.com/hs-fs/hubfs/Guide-SetLaser2Offset-HorizontalLineMeasure.png?width=688&height=281&name=Guide-SetLaser2Offset-HorizontalLineMeasure.png) - Reverse the Y offset sign if the output shifts in the incorrect direction. --- #### Notes and Tips: - **Machine Origin**: The origin is the location where the machine homes upon startup. - **Precision Matters**: Ensure all measurements are as accurate as possible for optimal results. - **Repeat if Needed**: Recheck and refine the offsets as necessary for perfect alignment. --- By following these steps, you can effectively align dual laser heads using LightBurn’s Laser 2 Offset feature, ensuring precise and consistent results in your laser projects. - [Lightburn](https://support.salasers.com/lightburn?hsLang=en#main-content) - [Lightburn For Galvo (Fiber)](https://support.salasers.com/lightburn?hsLang=en#lightburn-for-galvo-fiber) - [Lightburn For Gantry (Co2,RF)](https://support.salasers.com/lightburn?hsLang=en#lightburn-for-gantry-co2rf) - [Fiber (Galvo) Lasers](https://support.salasers.com/fiber-galvo-lasers?hsLang=en#main-content) - [Troubleshooting](https://support.salasers.com/fiber-galvo-lasers?hsLang=en#troubleshooting) - [Co2 Lasers](https://support.salasers.com/co2-lasers?hsLang=en#main-content) - [Razor Series](https://support.salasers.com/co2-lasers?hsLang=en#razor-series) - [Troubleshooting](https://support.salasers.com/troubleshooting?hsLang=en) - [EzCad 2](https://support.salasers.com/ezcad-2?hsLang=en) - [How-To Guides](https://support.salasers.com/how-to-guides?hsLang=en) - [Explainers](https://support.salasers.com/explainers?hsLang=en) - [Tools & Features](https://support.salasers.com/tools-features?hsLang=en#main-content) - [User Interface](https://support.salasers.com/tools-features?hsLang=en#user-interface) - [Essential Functions](https://support.salasers.com/tools-features?hsLang=en#essential-functions) - [Layout and Design](https://support.salasers.com/tools-features?hsLang=en#layout-and-design) # San Antonio Laser SALasers.com Help Center Copyright © 2026, San Antonio Laser
