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. System management relies primarily on the proprietary xTool Creative Space software, specifically developed to coordinate the machine's multi-function ecosystem. This application allows users to switch easily between laser engraving or cutting, blade die-cutting, and inkjet printing, while managing alignment via integrated sensors. The software is available for major desktop and mobile operating systems and supports both online and offline workflows. Although the interface is optimized to simplify the user experience, professionals accustomed to industry-standard platforms like LightBurn might experience operational limitations, as full support for the multi-tool capabilities strictly requires the manufacturer's official application.
