Overview:

Description:

The Anycubic ACE 2 Pro (Part Number: DS20BK1A-O) is a high-performance multi-material filament feed and drying hub specifically engineered for the Kobra 3 Max. This advanced accessory transforms your printing workflow by maintaining filament quality through active drying at temperatures up to 65degrees C while you print, ensuring consistent results free from moisture damage. It features four independent brushless motors that drive a buffer mechanism capable of feeding filament at an impressive 50 mm/s, significantly reducing jams and improving reliability. With smart sensors for real-time temperature and humidity monitoring, sealed storage capabilities, and durable alumina ceramic ports, this unit is designed to handle demanding materials like carbon fiber reinforced filaments with ease.

Key Features:

Upgrade your 3D printing setup with a system that combines speed, reliability, and intelligent moisture control. The ACE 2 Pro eliminates the frustration of wet filament ruining complex prints by actively drying spools and storing them in a sealed environment protected by an electromagnetic valve and silicone ring. Its high-speed feed rate ensures smooth transitions between colors or materials, while the quiet operation keeps your workspace peaceful.

• 4-channel active feed and retract system with independent brushless motors
• Active drying capability up to 65degrees C compatible with simultaneous printing
• Rapid filament feed rate of 50 mm/s for faster multi-material switching
• Built-in temperature and humidity sensors with real-time data on the app and printer screen
• Durable alumina ceramic feeding ports resistant to abrasion from composite filaments
• Sealed storage design that actively expels moisture via an electromagnetic valve
• Quick-release external buffer channel for effortless jam clearing
• Filament runout detection with auto-resume functionality to save prints
• Quiet operation under 48 dB during closed-door printing

FAQ

Is the Anycubic ACE 2 Pro compatible with printers other than the Kobra 3 Max?
The product information specifies that this hub is designed for the Anycubic Kobra 3 Max and mentions it is a next-generation feed system for Anycubic FDM printers including the Kobra 3 Max, but does not list other specific models as supported.

Can I dry my filament while the printer is actively running?
Yes, the ACE 2 Pro features an active drying system that reaches up to 65degrees C and works simultaneously with printing, allowing you to keep your spools fresh without stopping production.

What specific filaments are best suited for the drying function of this hub?
The device is most suitable for drying PLA, PETG, and PVB. It can also handle ASA, ABS, PET, PA, PC, PP, BVOH, POM, HIPS, and fiber-reinforced materials, though these are listed as compatible but not optimal for the active drying process.

How does the system prevent filament jams during operation?
The hub uses four independent brushless motors with a buffer mechanism to ensure smooth feeding at 50 mm/s. It also features an externally mounted quick-release PTFE tube that allows users to clear any jams quickly and easily.

What are the power requirements for operating this unit?
The ACE 2 Pro draws a maximum of 330W at 220V or 235W at 110V. It operates quietly, producing under 48 dB when used with closed-door printing.

Does the package include the Anycubic Kobra 3 Max printer?
No, this product only contains the ACE 2 Pro unit and associated accessories like power cords and tubes; it does not include the Kobra 3 Max printer or any additional filaments.
