Ortur LM3 40W vs Sculpfun G9
Technical comparison · Diode laser (405–460 nm)
LM3 40W leads on the available specs (starting with work area); G9 makes sense only for non-technical reasons (availability, support, ecosystem), or if the missing data matters in your case.

| Software notes | 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. | Compatible with the free proprietary SGD Laser software (optimized for galvo systems and recommended for beginners) and LightBurn (requires a license and is partially supported for advanced features). |
