Software notes The system is fully compatible with LightBurn, the industry-standard software for advanced vector preparation and control, and AtomStack Studio, the manufacturer's proprietary solution. It also features a built-in touchscreen for offline control, allowing complex jobs to be started without the need for a constantly connected computer. 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.
