| Software notes | The software compatibility of the device is extensive and aligns with the industrial standards of the maker sector. It natively supports both LaserGRBL, a free and open-source option suitable for basic engraving operations, and LightBurn, the most popular paid professional platform for advanced management of layers, cutting parameters, and complex vector formats. Control can be managed directly via a wired USB connection from a computer or in offline mode, using memory cards to load processing files. The machine responds to standard G-code commands, allowing experienced users fine customization of acceleration and speed parameters through the configuration of the internal firmware, without constraints linked to proprietary and closed-source cloud ecosystems. | The system offers extended compatibility with the industry's leading standard software, ensuring operational flexibility across both Windows and macOS platforms. It fully supports LightBurn, the preferred choice for professional users seeking advanced management of layers, cutting parameters, and vectorization, as well as LaserGRBL, an open-source alternative ideal for simpler and more immediate engraving operations. Additionally, the machine is compatible with the manufacturer's proprietary mobile application, enabling remote control and file transmission via local Wi-Fi. This triple option allows users to adapt their workflow to specific project needs, supporting common vector and raster file formats such as NC, DXF, BMP, and JPG. |
