| Cloud dependency | No | No |
| Software notes | The control of the machine is fully compatible with the industry standard LightBurn, ensuring users have access to advanced tools for design, layer management, and vector path optimization directly via USB connection. The proprietary software provided by the manufacturer is also supported, making it ideal for quick engraving and marking operations or for users who prefer a more streamlined interface. The absence of constraints related to cloud architectures ensures full hardware operability even in offline environments, protecting the confidentiality of work files and ensuring the tool's longevity is not dependent on external remote server support. | 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. |
