Anycubic Kobra S1 Max vs Qidi Tech Plus4
Technical comparison · Fused filament fabrication (FFF/FDM)
The Kobra S1 Max and the Plus4 are both enclosed FDM printers built for technical materials. The trade-off is build volume against software integration: the Kobra S1 Max has a larger bed and taller Z height, the Plus4 runs Klipper natively and handles more colors with its dedicated accessory.

| Software notes | The firmware runs on a proprietary Kobra OS layer built on top of Klipper; the official slicer is Anycubic Slicer Next, derived from OrcaSlicer, available for Windows and macOS. Third-party OrcaSlicer is also supported. Remote monitoring and control are available via the Anycubic app (iOS/Android) over LAN, with no mandatory cloud connection required for ordinary printing operations. Unlike the Combo version, the ACE 2 Pro module is not included in the box. | The machine relies on an architecture based on Klipper firmware, which provides advanced computational performance and native features like input shaping to reduce vibrations during high-speed movements. Users can interface via the integrated 5-inch touchscreen or through the standard Klipper web interface. The recommended official slicing software is QIDI Studio, a program derived from PrusaSlicer and Orca Slicer, optimized to leverage the machine's profiles and proprietary print parameters. However, the system maintains an open approach and is fully compatible with third-party slicers such as Orca Slicer, PrusaSlicer, and Cura, ensuring maximum flexibility in the daily workflow. |
The differences that matter
- Bed and height: 350×350 mm and 350 mm on the Kobra S1 Max versus 305×305 mm and 280 mm on the Plus4 → more room for large parts in one piece.
- Native Klipper: only on the Plus4 → direct macros and calibration, no proprietary fork.
- Colors with accessory: up to 16 on the Plus4 versus 4 on the Kobra S1 Max → more headroom for complex multicolor prints.
- Price: the Kobra S1 Max costs €100 less.
Which one to choose
Choose Kobra S1 Max if…
Pick it for bulky parts: the 350×350 mm bed and 350 mm Z height leave room to print in one piece objects that would need splitting on the Plus4. You give up native Klipper and top out at 4 colors with the dedicated accessory. It also costs €100 less.
Choose Plus4 if…
Pick it if you already work with Klipper profiles and macros: the native firmware lets you tune print parameters directly, with no proprietary layer in between. With the dedicated accessory it reaches up to 16 colors in the same part, versus 4 on the Kobra S1 Max. Its nozzle, per the manufacturer's declared values, reaches 370°C against 350°C. You pay €100 more and lose bed and height headroom.
