Software notes The LM3 uses firmware based on the open GRBL protocol, compatible with LightBurn (diode license ~$60 one-time), LaserGRBL (free, open-source), and the proprietary Ortur iOS/Android app with selectable novice and advanced modes. LightBurn offers advanced variable power control, path optimization, and optional camera alignment; LaserGRBL covers basic engraving tasks at no additional cost. The open GRBL protocol ensures compatibility with third-party tools and standard G-code generators. Communication is via USB; the Ortur app allows remote job launching via Wi-Fi without a connected PC. Machine control is flexible thanks to multi-platform support. The manufacturer provides the proprietary xTool Creative Space (XCS) software, which is free and intuitive, suitable for beginners and available for Windows, macOS, iOS, and Android, operating completely offline via USB connection or TF card. For advanced users requiring professional nesting, layer management, and path optimization features, the engraver guarantees full compatibility with LightBurn. The optimized firmware architecture allows for a smooth transition between both applications, supporting the import of standard vector and raster formats such as SVG, DXF, BMP, and JPG, without any dependence on external cloud services for daily operation.
