Anycubic Kobra S1 ACE 2 Pro Combo vs Artillery Sidewinder X4 Plus
Technical comparison · Fused filament fabrication (FFF/FDM)
Kobra S1 ACE 2 Pro Combo and Sidewinder X4 Plus play on two different fields: an enclosed chamber and 8-color multicolor on one side, a taller build volume and lower price on the other. The right pick depends on what you need to print, not an overall score.

| Software notes | Compatible with the main slicers on the market. It supports cloud connectivity via the Anycubic app and Wi-Fi for remote monitoring, while still allowing offline use via USB. | Compatible with Artillery Slicer and Cura; the Marlin firmware accepts standard G-code, so it works with PrusaSlicer, SuperSlicer, OrcaSlicer. WiFi file transfer does not offer a Klipper web interface, limiting remote monitoring and real-time adjustments. |
The differences that matter
- Multicolor: up to 8 colors on the Kobra S1 ACE 2 Pro Combo via the ACE system, single color on the Sidewinder X4 Plus.
- Z height: 400 mm on the Sidewinder X4 Plus vs 250 mm on the Kobra S1 ACE 2 Pro Combo — decides which tall parts fit in one piece.
- Chamber: enclosed on the Kobra S1 ACE 2 Pro Combo, useful for ABS and ASA.
- Firmware: native Klipper with a web interface on the Kobra S1 ACE 2 Pro Combo, Marlin without one on the Sidewinder X4 Plus.
Which one to choose
Choose Kobra S1 ACE 2 Pro Combo if…
Pick the Kobra S1 ACE 2 Pro Combo if you need multicolor: the ACE system handles up to 8 colors in the same print, and the enclosed chamber opens the door to materials like ABS or ASA that the Sidewinder X4 Plus, with no declared spec here, doesn't guarantee the same way.
Choose Sidewinder X4 Plus if…
Pick the Sidewinder X4 Plus if volume matters more than color: 400 mm of Z height against the Kobra S1 ACE 2 Pro Combo's 250 mm fits tall parts the other can't, at a lower price. It lacks the web interface for remote monitoring, though — that's only on Klipper-based firmware like the Kobra's.
