Anycubic Ace 2 Pro - For Kobra X and S1/M

4-channel active drying and feeding hub | Print-while-drying workflow | Brushless motors for quiet, reliable operation | Sealed moisture control | Compatible with Kobra X, S1, and S1 Max

Quick Specs

• Dry and print simultaneously with active 65 °C drying — keep your filament fresh without pausing a single job
• Feed four colours at once through four independent brushless motors running at under 48 dB for smooth, near-silent operation
• Switch filaments faster with a next-generation buffer mechanism that doubles loading speed compared to the previous generation
• Protect every spool with sealed storage, an electromagnetic moisture valve, and real-time temperature and humidity monitoring
• Built to last with an alumina ceramic filament feeding port that resists wear far longer than standard plastic alternatives

Upgrade Your Multi-Material Workflow

The Anycubic ACE 2 Pro is designed for FDM makers who want a reliable, intelligent hub to manage multiple filaments — drying them, feeding them, and keeping them in peak condition, all at the same time. Compatible with the Kobra X, Kobra S1, and Kobra S1 Max, it connects seamlessly into your existing setup and replaces the guesswork of manual filament management with a fully automated system.

Never Stop Printing to Dry Your Filament Again

Tired of halting your print jobs just to run a separate drying cycle? The ACE 2 Pro supports simultaneous drying and printing, maintaining a chamber temperature of up to 65 °C while your printer keeps running. Built-in temperature and humidity sensors monitor conditions in real time, an electromagnetic valve actively expels moisture, and a silicone sealing ring blocks external humidity from creeping back in. Your filament stays as fresh as the day it came out of the bag.

Faster, Quieter, More Reliable Feeding

Four independent brushless motors — each rated for a lifespan of 5,000 hours or more — drive the next-generation buffer mechanism, delivering smooth and stable filament feed and retraction across all four channels. Operating at under 48 dB during closed-door printing, the ACE 2 Pro keeps your workspace quiet. Filament loading speed is doubled compared to the previous ACE Pro generation, meaning less waiting between colour changes and more time spent actually printing. The alumina ceramic filament feeding port adds another layer of durability, offering superior abrasion resistance over standard plastic ports for reduced long-term maintenance.

Intelligent Monitoring and Jam-Free Maintenance

The ACE 2 Pro keeps you informed and in control. Real-time temperature and humidity readings are displayed on the app, slicer, and printer screen. Filament runout detection and auto-resume printing mean unexpected interruptions are handled automatically. When a jam does occur, the quick-release external feeding channel and buffer mechanism allow rapid disassembly so you can clear the issue and get back to printing in seconds. Intelligent filament identification auto-detects Anycubic filament parameters when connected — eliminating manual profile configuration for supported materials.
