| Software notes | The system is fully compatible with LightBurn, the industry standard for laser control, which allows users to easily manage the dual laser source for processing different materials without changing the head. For users looking for a plug-and-play solution, the proprietary AtomStack Studio software is available, compatible with Windows, macOS, and even mobile devices. The latter simplifies the use of the built-in 16 MP camera, optimizing the workspace preview for quick and precise positioning, thus reducing material waste. The machine supports job resume in case of power failure and can operate offline via a USB flash drive, ensuring an uninterrupted workflow even without a continuous connection to a computer. | Fully compatible with LightBurn and LaserGRBL via USB, Wi-Fi, or Bluetooth. It also supports the proprietary Sculpfun application. |
