| 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. | Natively compatible with PrusaSlicer (based on Slic3r, open-source), but it works with any slicer able to generate Marlin-flavored G-code, such as Cura, ideaMaker or Simplify3D. The firmware is a Prusa-modified Marlin 2, fully open: no lock-in to proprietary software or protocols. The user has full control over the machine, but PrusaSlicer is recommended for optimal performance, as it includes exclusive profiles and features like dynamic flow calibration. |
The differences that matter
- 549 € vs about 1049–1349 € → the Kobra S1 costs 500 to 800 € less.
- Up to 8 colours vs 5, accessory needed on both → more colours in the same part on the Kobra S1.
- Bed 250 × 250 mm vs 250 × 220 mm, height 250 vs 270 mm → 30 mm more depth on the Kobra, 20 mm more height on the CORE One+.
- Nozzle up to 320 °C vs 290 °C → filaments above 290 °C only on the Kobra S1.
Which one to choose
Choose Kobra S1 if…
A 250 × 250 mm bed, a nozzle up to 320 °C and up to 8 colours with native Klipper, for 549 €. The firmware is Kobra OS with a proprietary touch interface, and the slicer is Anycubic Slicer Next, derived from OrcaSlicer.
Choose CORE One+ if…
For those who want open Marlin firmware, PrusaSlicer with official profiles and no lock-in to proprietary software or protocols. You pay 500 to 800 € more (1049–1349 €) and get 5 colours, a 250 × 220 mm bed and a 290 °C nozzle; you gain 20 mm of height (270 mm).
