Product Summary
Anycubic Kobra S1 ACE 2 Pro Combo is a fully-enclosed CoreXY filament 3D printer aimed at makers who want multicolor production without running several machines side by side. The ACE 2 Pro material system ships as standard, so four-color printing is available immediately and the setup can grow toward sixteen colors with further ACE 2 Pro units. A recommended 300 mm/s working speed and a maximum of 600 mm/s sit inside a 250 mm cubic, enclosed build volume, with a 320°C hotend and a 120°C PEI spring steel plate covering PLA, PETG, ABS, ASA and direct-feed TPU. Automatic leveling, AI monitoring and power-loss recovery support long unattended jobs.
Highlights
Multicolor From Four to Sixteen
This combo pairs the Kobra S1 printer with one ACE 2 Pro unit, so four-color printing starts out of the box and sixteen colors are reached by running four units together. Four independent brushless feed motors plus a next-generation buffering mechanism keep every channel feeding and retracting smoothly, without jams.
Dries Filament While It Prints
The ACE 2 Pro dries filament while you print, holding its chambers at up to 65°C instead of making drying a separate chore. Built-in temperature and humidity sensors monitor the chamber, an electromagnetic valve actively expels moisture, and a silicone sealing ring blocks outside humidity during long storage.
Enclosed CoreXY at Print Speed
A fully-enclosed CoreXY frame, dual motor drive and Kobra OS work together to damp vibration, which lets the machine hold its recommended 300 mm/s working speed and a maximum of 600 mm/s. Resonance compensation and flow correction further minimize corner overflow, so tall, detailed multicolor models keep clean surfaces.
Quiet Enough for Shared Rooms
Noise is measured one meter in front of the printer: as low as 46 dB in standard mode and 44 dB in quiet mode. The ACE 2 Pro feeding unit itself runs under 48 dB, and its independent brushless motors are rated for at least 5000 hours of use, so an office or living space stays usable.
Engineering Materials, One Machine
The 320°C hotend and 120°C PEI spring steel build plate handle PLA, PETG, ABS, ASA and TPU, so engineering materials and colorful display pieces share one machine. The standard 0.4 mm nozzle can be replaced with a 0.25 mm tip for fine detail, or with 0.6 mm and 0.8 mm tips for faster, larger batches.
Catches Failures Before Morning
A standard HD camera gives 480P video monitoring, and AI spaghetti detection warns you when a print starts to collapse. Belt tension monitoring, foreign-object detection, filament runout response and power-loss recovery mean an overnight job can resume by itself rather than leaving you with a failed part.
Leveling, Slicing and Remote Control
LeviQ3.0 performs automatic bed leveling and Z-axis offset, while the 4.3-inch capacitive touchscreen lets you change parameters mid-print. Anycubic Slicer Next, built on the Orca open-source platform, offers one-click presets and multi-plate management, and the Anycubic app adds remote start, monitoring and time-lapse capture.

FAQ
What is the difference between the Kobra S1 ACE 2 Pro Combo and the Kobra S1 Combo?
The Kobra S1 ACE 2 Pro Combo comes standard with the ACE 2 Pro and supports up to 16-color printing, while the Kobra S1 Combo is equipped with the first-generation ACE Pro and supports up to 8-color printing. The ACE 2 Pro dries at up to 65°C during printing, monitors temperature and humidity, offers active moisture control with sealed storage and detects filament runout; the first-generation ACE Pro dries at up to 55°C only and has none of those functions.
What materials can the Kobra S1 ACE 2 Pro Combo print with?
It is compatible with PLA, PETG, TPU (95A), ABS and ASA. TPU (95A) is only suitable for single-color printing: because of the physical properties of TPU it must be fed directly into the printer and is not compatible with the ACE 2 Pro for multi-material printing.
Can I combine a first-generation ACE Pro with this printer for 8-color printing?
No. The ACE 2 Pro cannot be used together with the first-generation ACE Pro, because the simultaneous use of Generation 1 and Generation 2 multicolor systems is not supported.
What is the nozzle diameter?
The standard diameter is 0.4 mm, and it can be expanded to 0.25, 0.6 or 0.8 mm.
Important Notes
- One ACE 2 Pro unit is included, which gives four-color printing; an 8-color setup needs two units and a 16-color setup needs four, and those extra units are not part of this package.
- TPU (95A) must be loaded directly into the printer and cannot be fed through the ACE 2 Pro.
- The ACE 2 Pro cannot be mixed with the first-generation ACE Pro in one multicolor setup.
- USB flash drives are not part of the standard configuration, as cloud services now cover most of those functions.
- Automatic filament parameter identification requires an internet connection and Anycubic proprietary filaments.
- Single-click slicing from Makeronline requires a PC with the Anycubic slicing software installed.
- Where a filament bundle is selected, the filament types and colors included are supplied at random and may contain duplicate colors.
- Two plug variants are offered, a standard plug and an EU plug, so please confirm the version before ordering.
