Anycubic Kobra S1 V2 ACE 2 Pro Combo

The Anycubic Kobra S1 ACE 2 Pro Combo combines a fully enclosed CoreXY 3D printer with an ACE 2 Pro for four-color printing. It offers a build volume of 250 × 250 × 250 mm and a maximum print speed of up to 600 mm/s. The ACE 2 Pro supports in-print filament drying at temperatures up to 65 °C, along with active humidity control and real-time temperature and humidity monitoring. Automatic calibration, filament monitoring, AI detection features, and HD video monitoring support the printing process from setup to completion.

Highlights

• Four-color printing with the included ACE 2 Pro.
• Fully enclosed CoreXY structure with a build volume of 250 × 250 × 250 mm
• Maximum print speed of up to 600 mm/s
• In-print filament drying at temperatures up to 65 °C
• Nozzle temperature up to 320 °C and heated bed up to 120 °C
• LeviQ 3.0: Automatic leveling, AI automatic spaghetti detection, and HD camera monitoring.

Four-color printing with the ACE 2 Pro

The included ACE 2 Pro printer handles four filament channels for four-color printing. Four independent brushless motors and a buffer mechanism control filament feeding and retraction in individual channels.

The system displays an estimate of remaining filament and supports automatic filament replenishment based on pre-configured color and material profiles. Smart identification can automatically detect parameters for compatible Anycubic filaments. This feature requires an internet connection and proprietary Anycubic filament.

Active filament drying and humidity control

ACE 2 Pro supports simultaneous drying and printing, with a maximum drying temperature of 65 °C. Integrated temperature and humidity sensors monitor the unit's internal conditions in real time.

An electromagnetic valve actively removes moisture, while a silicone sealing ring helps prevent external humidity from entering the storage chamber.

Enclosed CoreXY printing

The fully enclosed CoreXY structure offers a print volume of 250 × 250 × 250 mm. The recommended print speed is 300 mm/s, with a maximum speed of up to 600 mm/s and maximum acceleration of up to 20,000 mm/s².

The motion system combines dual-motor drive with Kobra OS, resonance compensation, and flow correction. An integrated accelerometer detects resonance frequency, while flow compensation adjusts filament extrusion during printing.

Nozzle, build plate, and material support

The nozzle reaches temperatures up to 320 °C and has a standard diameter of 0.4 mm. The printer also supports nozzles with diameters of 0.6 and 0.8 mm. The heated bed reaches temperatures up to 120 °C and uses a PEI spring steel build plate.

Supported materials include PLA, PETG, TPU 95A, ABS, and ASA. TPU 95A must be fed directly into the printer and is not compatible with ACE 2 Pro for multi-color or multi-material printing.

Automated setup and print monitoring

LeviQ 3.0 offers automatic bed leveling and automatic Z-offset adjustment. The printer also supports pressure advance, flow calibration, filament runout detection with auto-resume, filament tangle detection, and power loss recovery.

The AI-based spaghetti detection system monitors prints for anomalies and provides alerts when a problem is detected. Additional monitoring features include belt tension checking, foreign object detection, object skipping, and area leveling.

Touchscreen, camera, and control options

The printer features a 4.3-inch capacitive touchscreen for direct operation and real-time parameter adjustment. Printing can also be controlled via slicing software, the Anycubic app, or USB, with the USB port supporting print transfer only.

A standard HD camera supports 480p video surveillance. Noise levels are specified at starting from 46 dB in standard mode and from 44 dB in quiet mode.
