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, rings. Works with many xTool lasers: P2, S1, F1, M1, D1 Pro, etc. |
RA3 | Newer “smart” rotary for xTool’s P Series. Adds features like MagSwap™ attachments, LiDAR mapping, auto-recognition of rotary mode, better jaws, etc. |
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: P2, S1, F1, M1, D1 Pro. | Made for P Series (P2, P3, etc.) 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. |
Price / Value | Lower price comparatively; solid for many users. | Higher price, but more features; better for users needing advanced rotary capability. |
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 P Series CO2 Laser. 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.

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 P Series CO2 Laser, 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.
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.
