| 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. | The LM3 uses firmware based on the open GRBL protocol, compatible with LightBurn (diode license ~$60 one-time), LaserGRBL (free, open-source), and the proprietary Ortur iOS/Android app with selectable novice and advanced modes. LightBurn offers advanced variable power control, path optimization, and optional camera alignment; LaserGRBL covers basic engraving tasks at no additional cost. The open GRBL protocol ensures compatibility with third-party tools and standard G-code generators. Communication is via USB; the Ortur app allows remote job launching via Wi-Fi without a connected PC. |
