[How-To Guides](https://support.salasers.com/how-to-guides?hsLang=en) # Setting Up Laser Offset for Accurate Alignment ## Overview Laser Offset Setup If your laser has a red dot pointer that is not aligned with the laser beam's actual position, you can use the **Laser Offset** feature in LightBurn to calibrate the beam's output. Proper setup ensures that the red dot matches the laser's working location, allowing you to: - Align output to material using **Current Position** or **User Origin**. - Accurately frame the output location. - Find the center of a circle using the **Center Finder** tool. When correctly configured, the laser head will adjust to match the red dot's position during alignment actions. --- ### Steps to Set Up Laser Offset #### 1. Initial Setup - Open **Device Settings** in LightBurn and ensure **Enable pointer offset** is disabled before proceeding. ![Guide-LaserOffset-OffsetDisabled](https://support.salasers.com/hs-fs/hubfs/Guide-LaserOffset-OffsetDisabled.png?width=222&height=75&name=Guide-LaserOffset-OffsetDisabled.png) #### 2. Prepare for Calibration - Load an expendable material into the laser bed where both the red dot and laser beam can mark. - Position the laser head over the material. - Download and import the **2-square pattern** into LightBurn. Assign the pattern to a layer set in **Line Mode** with appropriate settings for marking, not cutting. #### 3. Set Starting Parameters - In the Laser Window, select **Current Position** as the **Start From** mode and set the **Job Origin** to **Center**. ![Guide-LaserOffset-StartFromJobOrigin](https://support.salasers.com/hs-fs/hubfs/Guide-LaserOffset-StartFromJobOrigin.png?width=688&height=302&name=Guide-LaserOffset-StartFromJobOrigin.png) - For DSP devices: Navigate to **Edit → Machine Settings** and ensure **Return Position** is set to **No Return**. #### 4. Run the Initial Test Job - Press **Start** in the Laser Window to run the job and mark the material. - In the Move Window, press **Get Position** and record the X and Y coordinates reported. #### 5. Align the Red Dot - Move the laser head until the red dot is perfectly aligned with the center of the 2-square pattern (where the squares' bottom right and top left corners meet). - Press **Get Position** again and record the updated X and Y coordinates. ![Guide-LaserOffset-GetPosition](https://support.salasers.com/hs-fs/hubfs/Guide-LaserOffset-GetPosition.png?width=688&height=228&name=Guide-LaserOffset-GetPosition.png) #### 6. Calculate the Offset - Subtract the coordinates recorded in Step 5 from those recorded in Step 4 to calculate the offset: - Example: - **Step 4 X:** 180; **Step 5 X:** 200 → 180 - 200 = **-20**. - **Step 4 Y:** 200; **Step 5 Y:** 195 → 200 - 195 = **5**. #### 7. Apply the Offset - Open **Device Settings** and enter the calculated X and Y values in the **Laser Offset** section. ![Guide-LaserOffset-OffsetEnabled](https://support.salasers.com/hs-fs/hubfs/Guide-LaserOffset-OffsetEnabled.png?width=222&height=68&name=Guide-LaserOffset-OffsetEnabled.png) - Toggle on **Enable pointer offset**. - For DSP devices: Reverse the sign of the calculated values (e.g., -20 becomes +20). #### 8. Test the Calibration - Re-run the same job with the red dot aligned to the 2-square pattern. - The laser head should shift to match the red dot, and the output should align perfectly with the initial engraving. --- ### Troubleshooting 1. **Output Shifts in the Wrong Direction** - Reverse the sign of the X or Y offset in **Device Settings** (negative becomes positive and vice versa). 2. **Output is Slightly Misaligned** - Repeat the setup process, ensuring precise alignment of the red dot to the 2-square pattern. 3. **Alignment Drifts Over Time** - Verify that the red dot pointer is securely mounted and cannot shift. Re-run the calibration if necessary. - [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
