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 machine is compatible with major third-party software like LightBurn and can also be controlled via the proprietary Sculpfun app from mobile devices or PCs.
