| Software notes | The system is compatible with leading laser cutting and engraving software, such as LightBurn and LaserGRBL. The machine offers fully offline operation capabilities via its built-in touchscreen display, allowing users to manage jobs locally without the need for a permanently tethered computer during extensive runs. It supports standard G-code files and can be expanded with additional modules, such as the infrared laser for processing metals. | 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). |
