Anycubic Kobra 4 Combo

# Anycubic Kobra 4 Combo

Overview

The Anycubic Kobra 4 Combo pairs the open-frame Kobra 4 FDM/FFF printer with one ACE 2 Pro filament system for automated four-color printing. The printer provides a 260 × 260 × 260 mm build volume, while the included ACE 2 Pro adds four filament channels and active drying up to 65°C during printing.

Anycubic rates the Kobra 4 for 300 mm/s recommended print speed, 600 mm/s maximum print speed, and 20,000 mm/s² maximum acceleration. The hotend reaches 300°C and ships with a 0.4 mm hardened-steel nozzle, with 0.25, 0.6, and 0.8 mm alternatives available. The heated PEI spring-steel bed reaches 100°C.

LeviQ 3.0 handles automatic leveling and Z-offset setup, while flow calibration, vibration compensation, filament monitoring, object skipping, and a built-in 720p camera add everyday automation. The printer also supports dual-band Wi-Fi, LAN operation, Anycubic Slicer Next, the Anycubic App, and USB printing.

The Combo includes one ACE 2 Pro for four colors. To reach eight colors, Anycubic specifies a second ACE 2 Pro plus the compatible eight-color filament hub.

For current specifications and pricing, see the official Anycubic Kobra 4 Combo page and the official ACE 2 Pro page.

Technical Specifications

Speed note: 600 mm/s is Anycubic's maximum print-speed specification. The manufacturer recommends 300 mm/s for general high-speed printing.

What the Combo Adds

The Kobra 4 Combo uses the same printer platform as the standalone Kobra 4.

The difference is the included ACE 2 Pro.

The standalone Kobra 4 is a single-filament printer unless compatible multi-color hardware is added. The Combo package includes one ACE 2 Pro, giving the system four automated filament channels from the start.

ACE 2 Pro adds:

• Four filament positions
• Automatic feeding and retraction
• Four independent brushless feed motors
• Active drying up to 65°C
• Drying while printing
• Temperature and humidity monitoring
• Active moisture-control functions
• Automatic filament switching
• Multi-color workflow integration

This makes the Combo the more complete purchase for users who already know they want multi-color printing.

Four-Color and Eight-Color Printing

One ACE 2 Pro provides four-color printing.

Anycubic's Kobra 4 FAQ specifies that eight-color printing requires:

1. A second ACE 2 Pro
2. The compatible eight-color filament hub
3. The required connection hardware

The printer itself remains a single-nozzle system. During a color change, filament must be withdrawn and the next material loaded into the shared hotend.

That means multi-color printing still creates purge waste and transition time. The advantage of ACE 2 Pro is automation, drying, and material management rather than independent-tool, zero-purge printing.

ACE 2 Pro Drying

ACE 2 Pro's strongest practical advantage over many open multi-color spool holders is its 65°C active drying.

Anycubic supports drying while the printer is running, which can help maintain consistency during long PLA and PETG jobs.

The system also monitors temperature and humidity and uses active moisture-control features to manage the storage environment.

Drying temperature should still match the filament. More heat is not automatically appropriate for every spool or polymer.

Material Compatibility

Anycubic currently recommends the following materials for Kobra 4:

• PLA
• PETG
• TPU 95A

The printer's 300°C hardened-steel hotend provides useful thermal and wear resistance, but the official Kobra 4 material list is more conservative than the broader list published for Anycubic Kobra X.

TPU Limitation

Anycubic explicitly states that TPU 95A is not compatible with the ACE 2 Pro feed path.

TPU can therefore be printed directly on Kobra 4, but buyers should not expect flexible filament to participate in the standard ACE 2 Pro four-color workflow.

For flexible parts, direct feeding is the appropriate approach.

LeviQ 3.0 and First-Layer Calibration

The Kobra 4 uses LeviQ 3.0 with 49-point automatic leveling and automatic Z-offset preparation.

Anycubic also publishes leveling repeatability below 0.02 mm under its test conditions.

The system combines multiple measurement points into the compensation model rather than relying on manual adjustment across the build surface.

Automatic leveling improves first-layer consistency, but a clean PEI surface and correct filament temperature remain important.

Flow and Vibration Calibration

Kobra OS includes flow dynamic calibration that adjusts extrusion behavior to reduce over- and under-extrusion as printing conditions change.

A built-in accelerometer is used for vibration compensation, helping reduce ringing and ghosting at higher motion speeds.

These systems are especially relevant on a 600 mm/s-class bedslinger, where motion and extrusion tuning can have a large effect on visible print quality.

AI Monitoring and Recovery Features

The printer includes a 720p camera and Anycubic lists AI spaghetti detection as supported.

Other reliability features include:

• Filament runout detection
• Automatic resume after filament interruption
• Filament-entanglement detection
• Object skipping
• Area leveling
• Power-loss recovery
• Remote camera viewing
• Timelapse recording

AI monitoring can reduce the risk of wasting an entire long print, but it should be treated as an assistance feature rather than a guarantee that every failure will be detected.

Quiet Modes

Anycubic publishes noise figures of:

• ≤48 dB in standard mode
• ≤45 dB in silent print mode

These are manufacturer laboratory figures and can vary with print speed, fans, acceleration, table resonance, and the model being printed.

ACE 2 Pro also produces additional noise while feeding and drying, so the complete Combo may sound different from the printer operating alone.

Software, Wi-Fi and LAN

The Kobra 4 uses Anycubic Slicer Next and integrates with the Anycubic App.

Anycubic currently documents:

• Dual-band 2.4 / 5 GHz Wi-Fi
• LAN connectivity
• USB printing
• Cloud-connected remote operation
• Local-area-network workflow
• Remote monitoring
• Timelapse support

The ability to use LAN mode is useful for users who want network printing without depending entirely on an internet-connected cloud workflow.

Comparison Table: Affordable Multi-Color Desktop Printers

Kobra 4 Combo's clearest advantages are the included 65°C drying system, 260 mm cubic build volume, 600 mm/s headline speed, and hardened-steel nozzle. Its main limitation is the open-frame chassis and relatively narrow official material list.

Anycubic Kobra 4 Combo vs Bambu Lab A1 Combo

The Anycubic Kobra 4 Combo vs Bambu Lab A1 Combo comparison is one of the closest buying decisions in this price class.

The Bambu Lab A1 provides a 256 × 256 × 256 mm build volume, 500 mm/s maximum toolhead speed, 300°C hotend, 100°C bed, automatic calibration, active flow-rate compensation, and optional four-color printing through AMS lite.

Kobra 4 Combo is slightly larger at 260 mm in each axis and publishes a higher 600 mm/s maximum print speed. Its included ACE 2 Pro also adds 65°C active filament drying, which AMS lite does not provide.

A1 has the advantage of Bambu's mature AMS lite, Bambu Studio, and MakerWorld ecosystem, plus its active nozzle-pressure-based flow compensation.

Choose Kobra 4 Combo when active filament drying, a hardened-steel nozzle, slightly larger build volume, and Anycubic's current bundle pricing matter most.

Choose Bambu Lab A1 Combo when the Bambu software ecosystem and established AMS lite workflow are the higher priority.

Anycubic Kobra 4 Combo vs Anycubic Kobra X

The Kobra 4 Combo vs Kobra X comparison is especially important because both use a 260 × 260 × 260 mm build volume, 300°C hardened-steel nozzle, 100°C bed, 300 mm/s recommended speed, and 600 mm/s maximum speed.

The Anycubic Kobra X is the more advanced multi-color platform.

Anycubic gives Kobra X:

• Native four-color printing
• Expansion up to 19 colors
• ACE GEN 2 printhead architecture
• A broader published material list
• Soft/hard mixed-material capability
• Reduced filament-change length compared with previous ACE workflows

Kobra 4 Combo is simpler and currently cheaper. Its ACE 2 Pro gives it active drying out of the box, but it tops out at eight colors.

Choose Kobra 4 Combo for a straightforward four-color setup with active drying and lower entry cost.

Choose Kobra X when multi-color expansion, mixed-material flexibility, and Anycubic's newer ACE GEN 2 architecture justify the step up.

Anycubic Kobra 4 Combo vs Creality SPARKX i7 Nano

The Anycubic Kobra 4 Combo vs Creality SPARKX i7 Nano comparison covers two compact open-frame multi-color systems.

Creality's official SPARKX i7 Nano pairs a 260 × 260 × 255 mm SPARKX i7 with the compact four-channel CFS Nano system. The printer publishes a 500 mm/s maximum speed, 300°C hotend, 100°C bed, full-auto leveling, and a 720p AI camera.

Kobra 4 Combo provides 5 mm more Z height, a higher 600 mm/s headline print speed, and ACE 2 Pro's 65°C active drying.

SPARKX i7 Nano emphasizes a compact CFS Nano arrangement, quick-swap maintenance, AI monitoring, and Creality's lightweight home-oriented workflow.

Choose Kobra 4 Combo when active drying and eight-color expandability matter. Choose SPARKX i7 Nano when the compact Creality ecosystem and its i7 automation features are more appealing.

Anycubic Kobra 4 Combo vs Bambu Lab P2S

The Bambu Lab P2S is a more expensive enclosed alternative rather than a direct open-frame competitor.

P2S provides a 256 × 256 × 256 mm volume, 600 mm/s maximum toolhead speed, 20,000 mm/s² acceleration, 300°C hardened-steel nozzle, 110°C bed, 1080p camera, and support for ABS, ASA, PC, PA and numerous fiber-reinforced filaments.

Kobra 4 Combo has a slightly larger build volume and a lower entry price, while ACE 2 Pro provides drying and four-color printing in the standard Combo.

Choose Kobra 4 Combo for affordable PLA/PETG multi-color printing.

Choose P2S when an enclosure, broader engineering-material support, a stronger AMS ecosystem, and reinforced-material capability justify the higher purchase price.

Limitations and Practical Considerations

• The printer is open-frame, so it is not intended as a high-temperature engineering-material platform.
• Anycubic's official recommended material list is PLA, PETG and TPU 95A.
• TPU 95A is not compatible with the ACE 2 Pro feed path.
• Four-color and eight-color printing still create purge waste because all filaments share one nozzle.
• 600 mm/s is a maximum; Anycubic recommends 300 mm/s for general high-speed printing.
• ACE 2 Pro drying reaches 65°C, but drying temperature must still match the filament.
• Eight colors require a second ACE 2 Pro and the eight-color filament hub.
• Physical build-plate X/Y dimensions are not separately published from the 260 × 260 mm printable area.
• Input voltage and rated printer power are not currently listed in the main Kobra 4 specification table.
• AI spaghetti detection improves monitoring but does not guarantee every failure will be detected.
