| 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 compatible with leading laser cutting and engraving software, such as LightBurn and LaserGRBL. The machine offers fully offline operation capabilities via its built-in touchscreen display, allowing users to manage jobs locally without the need for a permanently tethered computer during extensive runs. It supports standard G-code files and can be expanded with additional modules, such as the infrared laser for processing metals. |
