| Software notes | The H2S uses Bambu Studio as its primary slicer, with full support for proprietary features including automatic calibration, AI monitoring, and AMS management. It also accepts G-code exported from OrcaSlicer, PrusaSlicer, and Cura, though some advanced functions may not be available with third-party slicers. Laser and cutting functions are managed exclusively through Bambu Suite. Developer Mode is available, exposing MQTT access for custom integrations. | The system relies on an architecture based on native Klipper firmware, a configuration that guarantees advanced kinematics management and precise control of accelerations through input shaping algorithms. The local and remote user interface is managed fluidly, allowing full monitoring of print parameters without the need to depend on mandatory external cloud services. For file preparation, the machine supports the main slicing software available on the market, including Qidi Print, OrcaSlicer, and PrusaSlicer, offering optimized profiles to enhance production times and the surface quality of components. Connectivity options include wired network and Wi-Fi, facilitating the integration of the device into local networks of laboratories or digital workshops. |
The differences that matter
- Declared top speed: 1000 mm/s (H2S) vs 600 mm/s (X-Max 3).
- Price: about €1200 (H2S) vs €899 (X-Max 3) → €300 in favor of the Qidi.
- Native Klipper: only on the X-Max 3.
- Multicolor: only on the H2S, with AMS as an accessory.
Which one to choose
Choose H2S if…
Suited to printing at high declared speed (up to 1000 mm/s) and wanting multicolor via AMS, with a build height reaching 340 mm. You accept no native Klipper and about €300 more.
Choose X-Max 3 if…
Suited to anyone wanting native Klipper for Fluidd/Mainsail access and firmware customization, at a lower price. You accept a lower declared top speed (600 mm/s vs 1000) and no multicolor printing.
