| 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 is fully compatible with LightBurn, the industry-standard software for advanced vector preparation and control, and AtomStack Studio, the manufacturer's proprietary solution. It also features a built-in touchscreen for offline control, allowing complex jobs to be started without the need for a constantly connected computer. |
