xTool Rotary Attachment 3 Lite

From Flat Tables to Curved Surfaces — Four Modes, One Attachment

Most laser engraving setups are constrained to flat stock. The xTool Rotary Attachment 3 Lite removes that constraint entirely. By rotating the workpiece in synchrony with the laser head's X-axis movement, it maps a flat vector path onto a curved surface with geometric precision — no distortion, no misaligned wrap lines.

The four supported modes address fundamentally different object geometries. Chuck mode grips objects by their diameter (0–100 mm), making it suitable for cylindrical items of varying sizes. Roller mode uses two drive wheels to support bottom-heavy or asymmetric cylinders in the 3–100 mm range. Sphere mode cradles spherical objects between 25 mm and 100 mm in diameter, while ring mode uses the included stud assembly to hold finger rings and small hoops between 11 mm and 70 mm.

The image below shows the jaw chuck assembly in close detail, illustrating the precision contact pins and the knurled brass adjustment wheel that governs clamping force.

Full-wrap engraving on revolving vases is among the most visually striking outputs this attachment enables. Because the M2's laser output is horizontal, the attachment orients workpieces so the beam sweeps across the full circumference in continuous passes — producing seamless 360° imagery that would be impossible to achieve on a flat bed.

The following image illustrates the range of everyday objects the attachment can personalise, from glass jars and candles to spherical items and tapered carafes.

MagSwap™ Magnetic Architecture — Why Speed of Setup Matters

In production workflows, transition time between job types is dead time. The MagSwap™ design addresses this directly. The jaw chuck, roller wheels, and support module all connect via magnetic quick-release interfaces — no screws, no Allen keys, no calibration after each swap. Switching from chuck mode to roller mode is a matter of seconds rather than minutes.

The clamping diameter adjusts instantly by rotating the knob and repositioning the jaws in one of three jaw configurations. Three jaw arrangements cover the full 5–125 mm working range: the first suits common rotating workpieces up to 95 mm; the second is optimised for large or smooth-surfaced objects up to 125 mm; the third serves small or lightweight items up to 108 mm. Each configuration snaps into place and locks with an audible click.

The image below demonstrates the MagSwap magnetic chuck system alongside the interchangeable jaw sets and alignment rod.

One-step ring positioning is handled by a fixed 26° tilt angle built into the stud assembly. No manual angle measurement, no iterative adjustment: place the ring, secure with the knob, and the geometry is already correct for inner-surface engraving. Note that due to the M2's horizontal laser output, inner ring engraving capability is limited compared to machines with a vertically adjustable laser path — a known M2-specific constraint that affects only this mode.

Structural Overview and Physical Footprint

The attachment measures 324 × 187 × 148 mm and weighs 2.26 kg — compact enough to store beside the M2 when not in use, yet rigid enough to maintain positional accuracy across a full engraving session. The slotted aluminium rail base and two positioning plates ensure the unit registers against the M2's internal reference point repeatably, eliminating the need to re-home the job origin between sessions.

The image below provides an isometric view of the complete rotary chuck attachment, highlighting the three-jaw grip mechanism, the knurled copper adjustment dial, and the slotted aluminium rail base.

Connectivity is handled by a single device connection cable routed through the M2's lid notch and plugged into any available extension port. The power module mounts directly to the main baseplate with a thumb screw, and the support module slides in from either end to accommodate long workpieces — or can be positioned outside the baseplate entirely for oversized items. Setup from a cold start to first engrave takes under five minutes.

Jaw Selection and Grip Security

Selecting the correct jaw type for a given workpiece is critical to both holding security and laser clearance. The three included jaw types serve distinct roles: cylindrical jaws and T-shaped jaws are recommended for the outermost holes of the chuck body, keeping the jaw profile low and away from the laser path. Extended jaws are best mounted in the middle or innermost holes and are primarily suited to objects below 80 mm in diameter. Mounting extended jaws in the outermost holes when other jaw types are also installed risks a collision between the laser module and the chuck body during travel — a hardware constraint worth understanding before configuring production runs.

The comparison below shows the RA3 T-type jaw chuck engaging a workpiece, alongside the roller configuration, demonstrating the 130 mm outer rim capacity.

For spherical objects, the support module's bell-mouth end provides passive stabilisation opposite the chuck jaws, preventing the sphere from rolling during the engraving cycle. No additional fixturing is required for objects up to 100 mm in diameter.

Tech Tip: Before your first session, use the included tape measure to measure each workpiece's diameter at the intended engraving zone — not at the widest point. Selecting the correct jaw configuration based on the actual engraving-zone diameter (rather than the object's maximum width) prevents grip slip mid-job and keeps the laser focal distance consistent throughout the rotation cycle.
