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

Upgrade your compatible Anycubic 3D printer with intelligent multi-colour filament management and active filament drying using the Anycubic ACE 2 Pro for Kobra X, Kobra S1 and Kobra S1 Max.

The ACE 2 Pro is an advanced 4-channel filament feeding, retracting, storage and drying system designed to automate filament changes while keeping compatible filament in better printing condition. With active drying up to 65°C, print-while-drying capability, four independent brushless motors, intelligent filament monitoring and sealed moisture control, it brings a more automated multi-colour printing workflow to compatible Anycubic FDM printers.

This version includes the adapter plate and return detection / 4-in-1 filament hub components required for compatible Kobra X, Kobra S1 and Kobra S1 Max installations.

Please note: This product contains the ACE 2 Pro and listed installation accessories only. A 3D printer and filament are NOT included unless specifically stated otherwise.

Add 4-Colour Printing to Your Compatible Anycubic Printer

The Anycubic ACE 2 Pro provides four independent filament channels, allowing a compatible printer to automatically manage multiple filament spools during a print.

Instead of manually unloading and loading filament whenever a colour change is required, the ACE 2 Pro handles filament feeding and retraction automatically.

This opens up a much wider range of creative possibilities for multi-colour models, signs, prototypes, artwork, educational projects, display pieces and functional prints.

For compatible systems that support additional ACE expansion, multiple units may also be used to unlock even greater multi-colour capability according to the printer's supported configuration.

Active Filament Drying up to 65°C

Moisture is one of the biggest enemies of consistent FDM 3D printing.

Filament can absorb moisture from the surrounding air, potentially resulting in inconsistent extrusion, poor surface finish and reduced print quality.

The ACE 2 Pro incorporates an active filament drying system capable of reaching temperatures up to 65°C, helping maintain compatible filament in better printing condition.

Dry Filament While You Print

One of the biggest advantages of the ACE 2 Pro is its ability to dry filament while printing.

Instead of removing your filament and running a separate drying cycle before starting a job, compatible filament can remain inside the ACE 2 Pro while the printer operates.

This creates a convenient continuous workflow, particularly for long prints or environments where humidity is a concern.

Four Independent Brushless Motors

Each filament channel is powered by its own independent brushless motor, providing controlled filament feeding and retraction across all four channels.

The motors are designed for reliable long-term operation while maintaining relatively low operating noise.

Combined with the updated buffer mechanism, the ACE 2 Pro provides faster and smoother filament handling than the previous-generation ACE Pro system.

Faster 50 mm/s Filament Feeding

The ACE 2 Pro can feed filament at speeds of up to 50 mm/s, approximately twice the feeding speed of the previous ACE Pro generation.

Faster loading and unloading can help reduce waiting time during automatic colour changes, which becomes increasingly important on complex multi-colour models requiring many filament swaps.

Intelligent Temperature & Humidity Monitoring

Built-in temperature and humidity sensors monitor conditions inside the ACE 2 Pro in real time.

Compatible environmental information can be viewed through the Anycubic ecosystem, including supported printer interfaces, slicing software and the Anycubic App.

This gives you greater visibility over filament storage and drying conditions without needing separate temperature or humidity monitoring equipment.

Active Moisture Removal

The ACE 2 Pro does more than simply heat the filament chamber.

An electromagnetic valve helps expel moisture from inside the unit during the drying process, improving the system's ability to manage humid air.

This works together with the active heating and monitoring system to create a more controlled environment for your filament.

Sealed Filament Storage

Once your filament is dry, keeping outside moisture away becomes equally important.

A silicone sealing ring helps reduce external humidity entering the ACE 2 Pro, allowing the enclosure to function as a more controlled filament storage environment.

The combination of active drying, moisture removal, temperature monitoring, humidity monitoring and sealed storage makes the ACE 2 Pro both a multi-colour filament system and an intelligent filament management solution.

Durable Alumina Ceramic Feeding Ports

Repeated filament movement can gradually wear conventional plastic feeding components, particularly when abrasive materials are used.

The ACE 2 Pro uses alumina ceramic filament feeding ports for improved abrasion resistance and durability.

This helps reduce wear at critical filament contact points and improves the system's suitability for regular long-term use.

Filament Runout Detection & Auto Resume

The ACE 2 Pro supports filament runout detection, helping protect long print jobs when a spool runs out unexpectedly.

When used with a compatible Anycubic printer and supported configuration, the system can assist with filament management and print continuation rather than allowing an empty spool to automatically ruin the entire job.

Intelligent Filament Identification

The ACE 2 Pro supports intelligent filament identification with compatible Anycubic filament.

When supported filament is installed and the required connected services are available, the system can automatically identify relevant filament information, helping reduce manual setup.

Compatibility and automatic identification functionality may depend on the filament, printer, firmware and connected configuration being used.

Quick-Release Design for Easier Jam Clearing

Filament jams shouldn't mean dismantling your entire filament management system.

The ACE 2 Pro features an accessible external feeding channel and quick-release buffer design, making it easier to access the filament path and clear blockages when required.

This reduces downtime and makes routine troubleshooting and maintenance more convenient.

Designed for Kobra X, Kobra S1 & Kobra S1 Max

This version of the ACE 2 Pro is specifically supplied with installation components for compatible:

Why Choose the Anycubic ACE 2 Pro?

The Anycubic ACE 2 Pro combines three useful functions in one intelligent system: multi-colour filament management, active filament drying and controlled filament storage.

Four independent filament channels automate feeding and retraction for compatible multi-colour printing, while the improved 50 mm/s feed rate helps reduce waiting time during filament changes.

At the same time, 65°C active drying, print-while-drying functionality, temperature and humidity monitoring, active moisture removal and sealed storage help keep compatible filament in better printing condition throughout long print jobs.

For owners of the Anycubic Kobra X, Kobra S1 or Kobra S1 Max who want to expand into multi-colour printing while gaining intelligent filament storage and drying, this version of the ACE 2 Pro provides the appropriate system and installation hardware for the upgrade.
