| 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 machine is managed through dual software compatibility that expands the user's operational possibilities. The proprietary program, developed directly by the manufacturer, provides an accessible interface and simplified positioning functions via sensors, facilitating workflow management even for less experienced operators. For professional contexts or advanced customization needs, the unit fully supports LightBurn, the industry standard for laser cutting. This integration allows the management of detailed parameters, complex vectorization, and customized material libraries. The machine operates primarily in local mode via USB connection or Wi-Fi network, reducing dependency on external cloud services and ensuring operational continuity even in the absence of a stable internet connection. |
