xTool RA2 Pro Rotary Attachment: RA2 Pro vs RA3
What We Know
Product | Key Description |
|---|---|
RA2 Pro | xTool’s 4-in-1 rotary engraving accessory. Includes rollers, chucks, spheres, and rings. Works with many xTool lasers: P2S, S1, F1, M1, D1 Pro, etc. |
RA3 | Newer “smart” rotary for xTool Lasers. Adds features such as MagSwap™ attachments, LiDAR mapping, auto-recognition of rotary mode, improved jaws, and more. Works with the xTool P3, F2 Ultra, F1 Ultra, and F2. |
Feature-by-Feature Comparison: RA2 Pro vs RA3
Feature | RA2 Pro | RA3 |
|---|---|---|
Attachment Types / Multi-Functionality | 4-in-1: rollers, chucks, spheres, rings. | Also supports multiple modes (rollers, chuck, etc.), but with quicker swap-out via MagSwap™ design. |
Software Features / Smart Automation | Basic rotary modes, no built-in LiDAR, manual setup. | Includes 360° LiDAR Mapping™, auto-recognition of rotary mode, previews in software, mismatch warnings if wrong mode selected. |
Compatibility (Machines) | Compatible with many xTool models: P2S, S1, F1, M1, D1 Pro. | xTool P3, F2 Ultra, F1 Ultra and F2 primarily. |
Ease of Use / Setup Speed | Decent, but swapping attachments and aligning takes manual work. | Faster: MagSwap™ design reduces time to switch modes or attachments. Auto features help reduce errors and alignment work. |
Gripping Capability / Size of Objects | Good for a variety of shapes thanks to chuck, rings etc. But gripping may require manual adjustment. | Improved jaws like T-type jaws, larger gripping range, easier clamp swaps. Better support for larger diameters or more complex shapes. |
Batch / Workflow Features | Works for small batch engraving. But lacks automation or preview tools. | Designed for better workflow: batch processing support, preview tools, faster mode switching. |
What It Means for Users / Which One to Choose
- If you’re a beginner or occasional engraver, mainly doing straight-sided tumblers, mugs, etc., the RA2 Pro gives you what you need without overpaying for features you may rarely use.
- Suppose you frequently work on tapered items, decorative rings, vases, or batch jobs, or want the fastest and most streamlined workflow with fewer manual adjustments, and own the xTool P3, F2 Ultra, F1 Ultra, or F2. In that case, the RA3 is likely the better investment.
- If software previews, mode auto-recognition, LiDAR mapping, and faster swapping of attachments matter to you, RA3 offers those smart enhancements that reduce setup mistakes and wasted materials.
Quick Setup Guide: How to Use the xTool RA2 Pro Rotary Attachment
Here’s a step-by-step guide to get you engraving your first tumbler with the RA2 Pro Rotary Attachment.
Step 1. Assemble the RA2 Pro
- Choose the right configuration (rollers for straight tumblers, chuck for tapered items).
- Place it on the laser bed.
Step 2. Connect to Your xTool Machine
- Use the correct cord for your model (S1, P2S, M1, or D1).
- Plug into the USB port to power the attachment.

- Use auto-measure for proper laser focus.
Step 6. Upload & Align Your Design
- Import your design into XCS.
- Rotate and align it with the tumbler orientation.
Step 7. Frame the Design
- Click Framing to preview the engraving area.
- Adjust placement before engraving.
Step 8. Start Engraving
- Click Process → Start in XCS.
- Vent your machine and turn on air assist if available.
- Let the RA2 Pro work its magic!
Pro Tip: After engraving, clean residue with a magic eraser + water for crisp, polished results
Can the xTool RA2 Pro Rotary Work With Other Laser Engravers?
Yes — the xTool RA2 Pro Rotary can work with other laser engravers, but it’s not always plug-and-play. Compatibility depends on your machine’s design and controller.
When It Does Work
The RA2 Pro is compatible with many open-frame diode laser engravers, such as:
- Ortur
- Atomstack
- NEJE
- Other GRBL-based machines
These engravers typically allow you to:
- Disconnect the Y-axis motor
- Plug in the rotary attachment instead
This lets the rotary take over movement for engraving cylindrical objects like tumblers or bottles.
What You Need for Compatibility
To use the RA2 Pro with a non-xTool machine, make sure:
- GRBL controller support (most diode lasers use this)
- Standard motor port connection (usually a 4-pin cable)
- Rotary settings available in software (like LightBurn or LaserGRBL)
You may also need:
- A compatible adapter cable (often included with the RA2 Pro)
- To manually configure steps per rotation in your software
When It Might NOT Work
The RA2 Pro may not be compatible with:
- Fully enclosed machines with proprietary systems
- Some CO₂ lasers (like Glowforge)
- Machines without accessible motor ports
- Non-GRBL controllers
Setup Overview
Typical setup involves:
- Unplugging the Y-axis motor
- Connecting the RA2 Pro to that port
- Enabling rotary mode in your software
- Adjusting settings (roller diameter, steps, etc.)
Bottom Line
- Works with many third-party diode engravers
- Requires manual setup and compatibility checks
- Not universal across all laser types
Final Thoughts: Is the RA2 Pro Worth It?
If you’re serious about laser engraving, the xTool RA2 Pro Rotary Attachment is a must-have. Whether you’re creating personalized tumblers for gifts, custom mugs for a small business, or experimenting with ornaments and rings, this tool unlocks endless project opportunities.
Beginners may feel intimidated at first, but once you run your first project, you’ll realize how easy—and rewarding—it is to use.
Our Recommendation: Start with a simple straight-sided tumbler project, then expand to tapered and more complex items as you get comfortable.

Frequently Asked Questions
Do I need the RA2 Pro or will the RA3 work for me?
If you mostly engrave straight-sided tumblers, mugs, or simple cylindrical objects, the RA2 Pro is more than enough. If you want faster setup, smarter features (like auto-recognition and LiDAR mapping), own a xTool P3, F2 Ultra, F1 Ultra, or F2, and plan to engrave tapered or complex shapes regularly, the RA3 is the better choice.
Can the xTool RA2 Pro Rotary Attachment engrave on glass tumblers and mugs?
Yes! The RA2 Pro, depending on the type of laser you have, works on glass, stainless steel, coated metals, and even wood cylinders.
Do I need risers to use the xTool RA2 Pro rotary attachment?
Yes, for taller objects like tumblers or mugs, you’ll need the xTool riser base to give your machine extra clearance. Without it, the laser head may not fit above your object.
How do I keep the tumbler from slipping on the rollers?
Slipping is common with smooth surfaces. You can add painter’s tape, rubber bands, or grip tape on the rollers to increase friction and keep your tumbler steady during engraving.
