When you export a ZIP from MOPA Color Studio, it contains everything you need to set up and run the job in LightBurn. Extract the ZIP to a folder before you begin.
mopa_project.lbrn. This file is included for reference only.mopa_project.lbrn, mopa_remap.png, and mopa_parameters.html.mopa_project.lbrn. All colours appear immediately in the workspace — already drawn, correctly positioned, and assigned to their own layers with MOPA parameters pre-loaded.mopa_remap.png alongside LightBurn to visually verify the zone layout matches your original image.Before engraving your final image, run a test card to verify your colours are dialled in correctly for your specific machine and material. This takes about 5 minutes and will save you wasted material on your final job.
mopa_test_card.lbrn and mopa_test_card.html.mopa_test_card.lbrn. You will see 29 colour swatches arranged in a 6×5 grid, each 10×10mm, on their own layers. Press Ctrl+A then Ctrl+G to group them.mopa_test_card.html in your browser. Compare each engraved swatch to its target colour. Use the Notes column to record which colours need adjustment — frequency up/down, power up/down, speed adjustment, additional passes.mopa_project.lbrn in LightBurn, group, position on your final material, and engrave with confidence.mopa_project.lbrn.| Problem | Solution |
|---|---|
| Layers panel is empty after opening .lbrn | Make sure you used File › Open, not File › Import. The .lbrn file must be opened, not imported. |
| SVG imports as an image, not a shape | This should not happen with MOPA Color Studio exports. If it does, check that you are importing the correct zone_NN.svg file and not the mopa_remap.png. |
| Colour is assigned to the wrong layer | Select the shape, then click the correct colour swatch in the Cuts / Layers panel. Refer to the import guide for the correct swatch for each colour file. |
| Shapes don't line up / overlap incorrectly | Ensure every colour SVG is set to X=0, Y=0, W=100mm. All colours share the same coordinate system and will stack correctly at those values. |
| Placeholder rectangles interfering with scan | Delete them before running — see step 8 above. They are 1×1 mm and will engrave if not removed. |
| Colours don't match expected results | Parameters are starting points. Adjust frequency ±10%, speed ±20%, or power ±5% and run test burns. Document what works for your specific machine and save as a preset. |
