Software notes Compatible with LightBurn, LaserGRBL, and any software that outputs G-code to a GRBL controller. The board uses open GRBL firmware, allowing for customizable engraving parameters without locking you into proprietary software. LightBurn requires a separate license (about €99). 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.
