Software notes Fully compatible with LightBurn and LaserGRBL via USB or Wi-Fi. It also offers the proprietary Ortur Laser Explorer app for controlling and sending jobs directly from a smartphone. The Ortur R2 operates exclusively with Ortur's proprietary mobile and desktop app, offering template-based design, sketch-to-engrave, and material-aware presets. No support for LightBurn, LaserGRBL, or any G-code sender; the control board uses a closed protocol. The built-in color touchscreen allows uploading files via USB for offline, PC-free repetition of the last 8 jobs. This simplifies use but prevents custom power/speed curves or integration with external camera systems.
