| Software notes | Fully compatible with LightBurn and LaserGRBL via USB, Wi-Fi, or Bluetooth. It also supports the proprietary Sculpfun application. | 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. |
