| Software notes | 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. | 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. |
