| Software notes | The printer works with Anycubic Slicer Next, derived from OrcaSlicer and optimized for the Anycubic ecosystem; it supports multi-plate management and object skipping during printing. Remote control and real-time monitoring are available through the Anycubic app (iOS and Android), connecting via LAN or cloud. The proprietary firmware is not currently open source; native Klipper compatibility is not supported. | Prusa firmware based on Marlin, fully open source, with built-in input shaper for faster and cleaner prints. Official slicer: PrusaSlicer (free, optimized profiles), compatible with Cura and Simplify3D. Control via USB, Ethernet or Wi-Fi with Prusa Connect (optional). No filament DRM: full freedom to use third-party materials. |
The differences that matter
- 749 € vs 1049 € → the Kobra S1 Combo costs 300 € less.
- Bed 250 × 250 mm vs 250 × 220 mm, height 250 vs 270 mm → the Kobra has 30 mm more depth, the CORE One+ 20 mm more height.
- Nozzle up to 320 °C vs 290 °C → filaments needing more than 290 °C only run on the Kobra.
- Proprietary firmware vs open Marlin with no filament DRM → on the CORE One+ third-party materials are unrestricted.
Which one to choose
Choose Kobra S1 Combo if…
Multicolour with no extra accessory needed, a 250 × 250 mm bed and a nozzle up to 320 °C, for 300 € less (749 € against 1049 €). The trade-off is proprietary firmware, not open source, and the Anycubic app for remote control.
Choose CORE One+ kit if…
A workshop that wants third-party filaments with no DRM and slicers other than PrusaSlicer: the firmware is open. You pay 300 € more and get a 250 × 220 mm bed, a nozzle that stops at 290 °C and a multicolour accessory (up to 5 colours); the height is 270 mm against 250 mm.
