| 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 control of the machine is fully compatible with the industry standard LightBurn, ensuring users have access to advanced tools for design, layer management, and vector path optimization directly via USB connection. The proprietary software provided by the manufacturer is also supported, making it ideal for quick engraving and marking operations or for users who prefer a more streamlined interface. The absence of constraints related to cloud architectures ensures full hardware operability even in offline environments, protecting the confidentiality of work files and ensuring the tool's longevity is not dependent on external remote server support. |
