Anycubic ACE Pro Review – Multi-Filament System, Compatibility, Problems & Real-World Use

If you’re running a Kobra 2 series printer and looking to step up your multi-color game while keeping filament moisture under control, the Anycubic ACE Pro might have caught your eye. This combined multi-filament feeder and dryer system promises to streamline your workflow, but does it deliver? Let’s dive into what this device actually does, where it shines, and where you might hit some bumps.

Introduction: What Is the Anycubic ACE Pro and Who Is It For?

The Anycubic ACE Pro is a multi-spool filament management system with an integrated dryer, designed specifically for Anycubic’s Kobra 2 printer lineup. Think of it as Anycubic’s answer to automatic material systems—it handles filament switching for multi-color prints while simultaneously keeping your materials dry and ready to print.

This system targets Kobra 2 Max users who want to experiment with multi-color printing without investing in a completely new printer. It’s also practical for anyone tired of dealing with moisture-related print failures, especially if you live in a humid climate.

It’s worth noting that rumors about an Anycubic ACE Pro 2 have been circulating, though nothing’s confirmed yet. If you’re not in a rush, keep an eye out for official announcements.

Anycubic ACE Pro Overview & Core Features

Anycubic ACE Pro at a Glance

The ACE Pro packs several key features into one unit:

• Multi-spool filament handling: Load up to four filament spools simultaneously, with automatic switching controlled by your slicer settings.
• Integrated filament dryer: Active heating and airflow work continuously to remove moisture from loaded spools—no more pre-drying in a separate food dehydrator.
• Automatic filament switching: During multi-color prints, the system handles filament changes without manual intervention, though purge blocks and waste are still part of the deal.
• Filament sensor system: Detects when filament runs out or encounters feed issues, pausing prints to prevent failures.
• Enclosed design for moisture control: The sealed chamber helps maintain low humidity levels around your filament while in storage mode.

What Makes the ACE Pro Different From Standard AMS Systems?

Compared to systems like the Bambu Lab AMS, the ACE Pro takes a slightly different approach. While Bambu’s system prioritizes speed and buffer management, Anycubic built the ACE Pro with active drying as a core feature rather than an add-on. This makes it particularly useful if you regularly print with hygroscopic materials like nylon or PETG.

The tradeoff? The ACE Pro is more ecosystem-locked than some competitors. It’s designed to work seamlessly with Kobra 2 printers but doesn’t offer the plug-and-play compatibility you might find with more universal systems. For Anycubic users, though, this tight integration means fewer configuration headaches and better out-of-box performance.

Anycubic ACE Pro Compatibility

Anycubic ACE Pro Compatibility – Supported Printers & Filaments

Let’s get straight to what matters: the Anycubic ACE Pro compatibility is limited but well-defined.

Firmware and hardware requirements:

You’ll need to ensure your Kobra 2 Max is running compatible firmware—check Anycubic’s official site for the latest version before connecting the ACE Pro. The physical connection uses a dedicated cable that links the ACE Pro’s control board to your printer’s mainboard.

Important considerations:

The Kobra 2 series uses a direct drive extruder setup, which generally handles the bowden-style feeding from the ACE Pro reasonably well. However, you’ll want to account for the additional path length when tuning retraction settings. Expect to add 1-3mm to your retraction distance compared to printing without the ACE Pro attached.

Space is another factor—the ACE Pro isn’t tiny. Make sure you have adequate room beside your printer, and consider whether the stock placement works for your setup or if you’ll need a custom stand.

Is the Anycubic ACE Pro Compatible With Klipper?

This is where things get a bit complicated. Anycubic ACE Pro Klipper support isn’t officially provided by Anycubic, which runs its own firmware on the Kobra 2 series.

Current status: If you’ve flashed your Kobra 2 to run Klipper, you’ll likely lose native ACE Pro functionality. The control protocol between the ACE Pro and printer is proprietary and not currently documented for Klipper implementation.

Community workarounds: Some advanced users have experimented with manual control scripts and sensor overrides, but these are hacky solutions at best. You might get basic feed/retract functionality working, but the automatic switching and sensor feedback that make the ACE Pro useful probably won’t work reliably.

Realistic expectations: If Klipper is non-negotiable for you, the ACE Pro probably isn’t the right multi-filament solution. Consider systems with open protocols or wait to see if community firmware matures. For stock Kobra 2 Max users, though, the integration works as intended.

Filament Handling & Dryer Performance

Anycubic ACE Pro Dryer – Does It Actually Work?

The integrated dryer is one of the ACE Pro’s main selling points, so let’s talk real-world performance.

Supported filament types:

The Anycubic ACE Pro dryer handles most common materials:

• PLA: Works great, though PLA rarely needs aggressive drying. The ACE Pro keeps it fresh for storage.
• PETG: This is where the dryer shines. PETG loves to absorb moisture, and the ACE Pro maintains it at printable humidity levels.
• ABS: Dries effectively, though you’ll want to verify temperature settings match your specific filament brand.
• TPU: This is where limitations appear. While the dryer can handle TPU moisture-wise, the feeding mechanism struggles with flexible filaments (more on this below).

Temperature control and airflow:

The ACE Pro uses preset temperature profiles for different material types. You select your filament from the interface, and it applies the appropriate heat. The airflow system circulates warm air through the chamber—it’s not as aggressive as dedicated dehydrators, but it maintains low humidity during extended prints.

Moisture removal effectiveness:

In practical use, the dryer works well for maintenance drying—keeping already-dry filament in good condition. If you’re starting with soaking wet filament that’s been sitting in a humid garage for months, you’ll want to pre-dry it in a dedicated dehydrator first, then use the ACE Pro to maintain that dry state.

For most users printing regularly, this approach works fine. The ACE Pro won’t replace a proper dehydrator for rescue missions, but it prevents problems before they start.

Using TPU With the Anycubic ACE Pro

Anycubic ACE Pro TPU printing is possible but comes with caveats.

What works:

Stiffer TPU variants (95A shore hardness and above) can feed through the ACE Pro’s bowden tube setup with careful tuning. You’ll need to:

• Slow down your print speed significantly (30-40mm/s max)
• Increase tension on the feeder mechanism
• Use minimal retraction (0.5-1mm)
• Keep the filament path as straight as possible

What doesn’t:

Soft, flexible TPU (85A and below) struggles badly with the ACE Pro. The long bowden path from the ACE Pro to your extruder creates too much opportunity for the filament to compress and jam. Even with perfect tuning, you’ll face inconsistent extrusion and frequent failures.

Software & Setup Experience

Anycubic ACE Pro Software – Setup, Features & Stability

The Anycubic ACE Pro software experience centers around Anycubic’s slicer, which is based on Cura but customized for their ecosystem.

Software overview:

Within the Anycubic slicer, you’ll find ACE Pro-specific settings for filament mapping. This lets you assign which spool position (1-4) contains which color, and the slicer automatically generates the switching commands during multi-color prints. The interface is straightforward—select your base printer profile (Kobra 2 Max + ACE Pro), paint your model with different colors, and slice.

Filament mapping and switching logic:

The switching logic prioritizes minimizing changes, grouping areas by color to reduce wasted filament during purges. You can adjust purge volume and prime tower settings, though the defaults work reasonably well for PLA. PETG might need increased purge volumes to prevent color contamination.

Anycubic ACE Pro software download:

You’ll grab the latest slicer version directly from Anycubic’s website. The software is free and receives periodic updates. Make sure you’re running the most recent version, as early releases had bugs with filament sensor handling.

Firmware updates:

The ACE Pro itself can receive firmware updates through the connected Kobra 2 Max. These updates address sensor calibration, feeding algorithms, and dryer temperature profiles. Check for updates monthly if you’re having issues.

Stability and known bugs:

Current software is mostly stable, but some users report occasional sensor false-positives that pause prints unnecessarily. This seems to happen more frequently with lighter-colored or translucent filaments that don’t trigger the optical sensor consistently. The workaround is ensuring filament is seated properly and the sensor window is clean.

Anycubic ACE Pro Manual & Initial Setup

The Anycubic ACE Pro manual is… adequate. It covers the basics but assumes you’re already familiar with multi-filament systems.

What the manual covers well:

• Physical assembly and cable connections
• Loading filament into each slot
• Basic software installation
• Troubleshooting common error codes

What’s missing or unclear:

• Advanced tuning for different filament types
• Detailed explanations of sensor calibration
• Best practices for maintenance and cleaning
• Tips for optimal spool placement to reduce tangling

Setup time:

For beginners, expect 1-2 hours to unbox, assemble, connect cables, and run your first successful multi-color print. Experienced users familiar with multi-material printing can probably cut that to 30-45 minutes. The physical assembly is straightforward—most of your time will be spent in the slicer learning the filament mapping interface.

Common Problems & Troubleshooting

Common Anycubic ACE Pro Problems (And How to Fix Them)

Let’s tackle the issues users actually encounter in the field.

Anycubic ACE Pro Filament Stuck Issues

Anycubic ACE Pro filament stuck scenarios are among the most common complaints.

Common causes:

• Filament tangling on the spool before it reaches the ACE Pro
• Debris or dust buildup in the feed path
• Incorrect tension settings for your specific filament brand
• Heat creep causing filament to soften in the wrong location

Step-by-step fixes:

1. Unload the filament completely: Use the manual unload function in the interface rather than pulling by hand
2. Inspect the feed path: Look for visible obstructions, bent tubing, or sharp bends in the bowden tube
3. Clean the entry and exit points: Use compressed air to clear dust from the sensor area and tube connections
4. Check spool rotation: Ensure your filament spool spins freely and isn’t binding
5. Reload with proper technique: Feed filament manually until it reaches the extruder, then use the automatic load function

Prevention tips:

• Use high-quality filament spools that rotate smoothly
• Keep the ACE Pro away from direct sunlight and heat sources
• Perform monthly cleaning of the feed path
• Don’t overload the dryer—running at max temperature constantly can cause issues

Anycubic ACE Pro Not Feeding Filament

When your Anycubic ACE Pro not feeding situations occur, it’s usually sensor-related or mechanical.

Sensor misreads:

The optical filament sensor sometimes fails to detect dark filaments or struggles with translucent materials. This causes the system to think filament is missing when it’s actually present. Try:

• Cleaning the sensor lens with isopropyl alcohol
• Verifying filament diameter consistency (measure with calipers—should be 1.75mm ±0.05mm)
• Adjusting sensor sensitivity in firmware settings if that option becomes available in future updates

Spool tension issues:

If the motor is running but filament isn’t advancing, check:

• The tension arm pressure—too loose and the drive gear slips, too tight and it deforms the filament
• Drive gear teeth for embedded filament dust (clean with a brass brush)
• Bearing quality on the idler arm (some units ship with rough bearings that bind)

TPU-specific problems:

Flexible filaments compress instead of pushing through when tension is wrong. For TPU, you need goldilocks tension—firm enough to grip, light enough not to compress. This takes trial and error. Start with minimal tension and increase gradually until you get consistent feeding.

Filament Sensor Errors & Misfeeds

Anycubic ACE Pro filament sensor malfunctions create frustrating print interruptions.

Calibration tips:

While there’s no manual calibration procedure in the current firmware, you can improve sensor reliability:

• Ensure the filament path is perfectly aligned through the sensor gate
• Avoid using filaments with diameters at the extreme ends of tolerance
• Keep the sensor area clear of filament dust and oil from handling

When replacement is needed:

If you consistently get false runout errors across multiple spools and filament types, and cleaning doesn’t help, the sensor itself might be faulty. Contact Anycubic support—sensors are a known wear item and they’re usually good about replacements under warranty.

Parts, Accessories & Maintenance

Anycubic ACE Pro Parts, Accessories & Upgrades

Anycubic ACE Pro parts availability is decent for a relatively new product.

Common Anycubic ACE Pro replacement parts:

• Filament sensors (most frequently replaced)
• PTFE bowden tubing (standard 4mm OD, 2mm ID)
• Drive gears and tension springs
• Heating elements for the dryer chamber
• Replacement fans for airflow system

Availability and pricing:

Anycubic sells parts through their official store, though availability varies by region. Third-party options exist for generic components like bowden tubing and fans. Sensors and proprietary electronics need to come from Anycubic directly.

Expect to pay $10-15 for sensors, $20-30 for heating elements, and $5-10 for mechanical parts. Stock up on spare sensors and tubing if you print heavily—these wear out fastest.

What wears out fastest:

In order of replacement frequency:

1. PTFE tubing (especially at connection points)
2. Filament sensors (dust accumulation and wear)
3. Drive gear teeth (filament dust embedding)
4. Tension springs (loss of pressure over time)

Anycubic ACE Pro Stand & Mounting Options

The Anycubic ACE Pro stand situation depends on your workspace.

Stock placement vs custom stands:

The ACE Pro ships with mounting hardware to sit beside your Kobra 2 Max at the same height. This works fine if you have lateral space. If you’re tight on width but have vertical room, several community-designed stands on Printables and Thingiverse let you mount the ACE Pro above or behind your printer.

Space-saving setups:

Consider vertical shelving solutions if your printer sits on a cart or desk. Mounting the ACE Pro on a shelf above your printer reduces the horizontal footprint while maintaining easy access to all four spool positions.

Printable stand recommendations:

Search for “Kobra 2 Max ACE Pro stand” on Printables. The most popular designs include:

• Vertical tower stands that place the ACE Pro behind the printer
• Desk clamp mounts for hanging the unit off the edge of a table
• Enclosure-integrated stands if you’re building a full printer enclosure

Print these stands in PETG or ABS for temperature resistance, especially if your printer environment gets warm.

Anycubic ACE Pro Filament Guide & Mod Options

The Anycubic ACE Pro filament guide path can be optimized.

Reducing friction:

The stock bowden tube path sometimes creates unnecessary friction points. Consider:

• Using Capricorn XS tubing (tighter tolerances, smoother interior)
• Adding guide clips to prevent tube sagging
• Keeping tube runs as straight as possible with minimal bends

Improving reliability:

Some users add external filament guides between the ACE Pro and printer to keep the bowden tube aligned. Simple printed clips attached to your printer frame work well.

Community mods worth mentioning:

• Spool holders with bearings for smoother rotation
• Sensor shield mods that prevent ambient light from affecting optical sensors
• Improved dust filters for the dryer air intake
• Silica gel holders integrated into the chamber for extra moisture control

Most of these are available as free STL files from the community. They’re optional but can improve your experience if you’re printing heavily.

Disassembly & Repairs

Anycubic ACE Pro Disassembly – What You Can (and Shouldn’t) Open

Anycubic ACE Pro disassembly should be approached carefully.

Safe disassembly areas:

You can safely access:

• Spool chamber covers (for cleaning and maintenance)
• Filament sensor housings (for replacement)
• Bowden tube connections
• Fan assemblies (for cleaning or replacement)

These areas are designed for user maintenance and won’t void your warranty if handled properly.

What voids warranty:

Opening the main electronics compartment or tampering with the heating element assembly will void your warranty. Unless you’re experienced with electronics repair and accept the warranty loss, leave these areas alone.

When to replace vs repair:

For mechanical parts like sensors and fans, replacement is straightforward and cost-effective. For electronic failures involving the main board or power supply, contact Anycubic support rather than attempting repairs—these components are complex and failure modes aren’t always obvious.

If your unit is under warranty and experiencing issues, always try Anycubic’s support channel first. They’re generally responsive and will send replacement parts or provide RMA if needed.

Anycubic ACE Pro Price & Value

Anycubic ACE Pro Price – Is It Worth It?

Let’s talk money. The Anycubic ACE Pro price typically ranges from $199 to $249 depending on sales and region.

What’s included:

• ACE Pro main unit with four spool holders
• Connection cable for Kobra 2 series
• PTFE bowden tubing
• Mounting hardware
• Power supply
• Basic documentation

Value compared to alternatives:

Against single-spool dryers ($50-80), you’re paying a premium but getting multi-filament capability and automatic switching. That’s a reasonable deal if you actually need those features.

Compared to competing AMS-style systems, the ACE Pro sits in the mid-range. Bambu’s AMS costs slightly more but offers broader compatibility. Generic multi-material units can be cheaper but lack the integrated drying and tight ecosystem integration.

The value proposition:

If you own a Kobra 2 Max and want to experiment with multi-color prints while keeping filament dry, the ACE Pro delivers good value. You’re getting a purpose-built solution that integrates cleanly without firmware hacking or adapter cables.

If you’re not committed to the Anycubic ecosystem, or if you print primarily with single colors, the value proposition weakens. A simple dry box and manual spool changes might serve you better for less money.

Anycubic ACE Pro vs ACE Pro 2 (What We Know So Far)

Anycubic ACE Pro 2 – Should You Wait?

Rumors about an Anycubic ACE Pro 2 have been circulating in community forums, but take everything with a grain of salt.

Rumors vs confirmed info:

As of now, Anycubic hasn’t officially announced an ACE Pro 2. Speculation suggests:

• Improved filament sensor reliability
• Broader printer compatibility (possibly including non-Anycubic machines)
• Better TPU handling
• Enhanced software features

None of this is confirmed. It’s all based on community wishlist items and typical product lifecycle patterns.

Likely improvements:

If Anycubic does release a version 2, you’d reasonably expect:

• Bug fixes for known sensor issues
• Updated firmware with better tuning options
• Possibly larger capacity or faster switching
• Refined industrial design based on user feedback

Buying advice depending on user profile:

Buy now if: You own a Kobra 2 Max, want to start multi-color printing soon, and the current ACE Pro meets your needs. The existing version is functional and supported.

Wait if: You’re not in a rush, your current single-spool setup works fine, or you’re hoping for significant feature upgrades. There’s always something better on the horizon in tech—you’ll be waiting forever if you chase every rumored update.

Consider alternatives if: You need multi-brand compatibility, TPU is a primary material, or you’re running Klipper. The ACE Pro might never be the right tool for those use cases.

Pros & Cons

Anycubic ACE Pro Pros and Cons

Final Verdict: Should You Buy the Anycubic ACE Pro?

Here’s the bottom line.

Best for:

The ACE Pro excels for Kobra 2 Max owners who want to add multi-color capability without buying a new printer. If you’re printing decorative items, prototypes with color-coded parts, or models that benefit from support interfaces in different materials, the ACE Pro streamlines that workflow significantly.

It’s also great for users in humid climates who’ve struggled with moisture-related failures. The integrated dryer eliminates a separate piece of equipment and keeps filament in ready-to-print condition.

Not ideal for:

If you’re a heavy TPU user, the ACE Pro will frustrate you. The bowden-style feeding path doesn’t handle flexible materials reliably enough for production use.

Klipper-first setups should look elsewhere—the proprietary communication protocol means you’ll lose functionality if you flash custom firmware.

Users wanting universal compatibility across multiple printer brands won’t find it here. This is an Anycubic ecosystem product through and through.
