| Software notes | The Kobra OS firmware is based on Klipper and controlled via a proprietary touch interface. The official slicer is Anycubic Slicer Next (derived from OrcaSlicer, available for Windows and macOS), but it also supports third-party OrcaSlicer. Remote control is possible via the Anycubic app (iOS/Android) over a local network, with no mandatory cloud connection for daily operations. | 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
- €549 vs €799 → €250 left over for accessories and filament.
- Bed 250×250 mm and Z 250 mm vs 305×305 mm and Z 280 mm → a part 300 mm wide does not fit on the Kobra.
- Nozzle at 320 °C vs 370 °C → materials that need more temperature stay off the Kobra.
- Up to 8 colors vs up to 16, both with an accessory → more colors per part on the Plus4.
Which one to choose
Choose Kobra S1 if…
Your parts fit in 250×250×250 mm and you want a more compact machine, 40×41×49 cm and 18 kg, with the Anycubic app on the local network and no mandatory cloud. You spend €549 against €799. The trade-off: the nozzle reaches a declared 320 °C against 370 °C, and multicolor needs an accessory, as on the Plus4, but stops at 8 colors.
Choose Plus4 if…
You print bigger parts, up to 305×305×280 mm, or materials that need a nozzle up to a declared 370 °C, and you work with QIDI Studio or with Orca and Cura. Multicolor needs an accessory and reaches 16 colors. The trade-off: €250 more and a bulkier machine, 50×49×55 cm and 27 kg.
