Anycubic Kobra X Combo vs Artillery Sidewinder SW-X2
Technical comparison · Fused filament fabrication (FFF/FDM)
Budget decides here: the Sidewinder SW-X2, from 2021, costs about 300 euro less and has more room, while the Kobra X Combo, from 2026, runs firmware derived from Klipper. The question is whether the newer firmware is worth that gap.

| Software notes | Powered by Kobra OS (a Klipper fork), it features Wi-Fi connectivity, vibration compensation, dynamic flow calibration, and a camera with built-in AI detection. | Compatible with any slicer that generates standard G-code, such as Cura, PrusaSlicer, Simplify3D, IdeaMaker. The machine uses open-source Marlin 2.0 firmware with no proprietary locks. The communication protocol is standard USB serial, not GRBL, with profiles widely documented by the community. |
The differences that matter
- Price 589 € against about 285 € → the Sidewinder costs about 300 euro less.
- Height 400 mm against 260 mm, bed 300 × 300 mm against 260 × 260 mm → a 35 cm part prints whole on the Sidewinder.
- Marlin 2.0 with no proprietary locks → any slicer that outputs standard G-code works on the Sidewinder.
Which one to choose
Choose Kobra X Combo if…
you want the Kobra OS firmware, derived from Klipper, with Wi-Fi, and 260 × 260 × 260 mm of volume is enough. You pay about 300 euro more and give up space: the Sidewinder reaches 300 × 300 × 400 mm.
Choose Sidewinder SW-X2 if…
you print on 300 × 300 mm and up to 400 mm high while spending about 300 euro less, with open Marlin 2.0 firmware that accepts Cura, PrusaSlicer, Simplify3D and IdeaMaker. You take a machine from 2021, without Klipper-derived firmware.
