Anycubic Kobra S1 Combo vs Snapmaker J1s
Technical comparison · Fused filament fabrication (FFF/FDM)
Two enclosed machines with different logic: the Kobra S1 Combo has a single extruder and costs €749, the Snapmaker J1s has two independent extruders (IDEX) and costs around €1,250. The question is whether you need the second extruder.

| 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. | It comes with the proprietary Snapmaker Luban software, a free, unified application available for Windows, macOS, and Linux. Luban is tailored to fully utilize the independent dual extruders (IDEX), integrating ready-to-use profiles for various print modes (Copy, Mirror, Backup). Compatibility with major third-party slicers, such as Cura or PrusaSlicer, is also ensured via standard G-code export. Direct machine control is facilitated by the integrated Android-based touchscreen display and Wi-Fi connectivity for remote management. |
The differences that matter
- One extruder vs two independent ones → only the J1s runs dual-extruder jobs, with Copy, Mirror and Backup modes.
- Area 250×250 mm vs 300×200 mm → the J1s is 5 cm wider, the S1 is 5 cm deeper and taller.
- €749 vs around €1,250 → the gap pays for IDEX, not for more volume.
- Anycubic Slicer Next and app vs Luban → two different software environments; the J1s also takes Cura and PrusaSlicer through standard G-code.
Which one to choose
Choose Kobra S1 Combo if…
For printing one part at a time on 250×250 mm, up to 250 mm tall, at around €500 less. Bed up to 120 °C and nozzle up to 320 °C (manufacturer's declared values). You accept proprietary firmware without native Klipper, run from Anycubic Slicer Next and the app.
Choose J1s if…
For work that needs two independent extruders, with ready-made Luban profiles for Copy, Mirror and Backup modes. It costs around €500 more, the area is 300×200 mm with 200 mm of height and the bed reaches 100 °C.
