| Software notes | The system offers excellent versatility in terms of software control, ensuring native compatibility with standard solutions in the maker industry. It fully supports LightBurn, the most popular professional application for laser cutting and engraving management, and LaserGRBL, an open-source alternative ideal for more straightforward operations. Additionally, the machine features wireless connectivity capabilities that allow file transmission and monitoring via a proprietary mobile application, optimizing the workshop workflow. The absence of restrictions tied to proprietary cloud ecosystems ensures complete offline operational continuity, protecting project privacy and ensuring that the machine remains fully functional regardless of local network conditions. | Fully compatible with LightBurn and LaserGRBL via USB, Wi-Fi, or Bluetooth. It also supports the proprietary Sculpfun application. |
