| 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. | Fully compatible with LightBurn and LaserGRBL, offering WiFi, USB connectivity, and offline control via the integrated TS1 touchscreen or proprietary app. |
