Laser Rotary Attachments

A rotary attachment lets you engrave the curved surface of a cylinder (tumbler, glass, ring, pipe, knife handle) by rotating the workpiece while the laser scans one axis. Three main mechanical styles: roller (cheapest, friction-driven, slips), chuck (jaws clamp the part, most accurate), and jaw / pinch (compromise). Almost all support LightBurn's rotary mode; many ship with their own GRBL-axis offset config.

Universal hobby rotaries

• ★ xTool RA2 Pro — closed product, ~$200; 4-in-1 rotary (chuck, roller, ring, sphere). The most-bought hobby rotary on the market in 2025–2026; designed for xTool diode/CO2 but works on any GRBL-rotary-capable machine. Drives via XCS or LightBurn rotary mode.
• ★ Roly RotaryMax — open product, ~$150; chuck-style rotary popular among Ortur / Sculpfun / OMTech owners. Strong at tumblers and bottles. LightBurn-friendly.
• OMTech rotary roller — bundled with OMTech CO2 fiber; basic friction-roller design.
• Sculpfun rotary roller — lower-cost roller; fine for tumblers.
• Ortur YRR / YRR 2.0 — Ortur's roller-style rotary; cheap.
• TwoTrees rotary roller — same category, value-tier.

Chuck rotaries (most accurate)

• ★ Cloudray FDA chuck rotary — premium chuck rotary for fiber-galvo; precise indexing, good for rings and small cylinders.
• OMTech chuck rotary — heavier-duty; works on CO2 + fiber.
• MonportLaser chuck rotary — value alternative.
• Cloudray 4-jaw self-centering chuck — for non-round / square / hex stock.

Roller-style (cheapest, fastest setup)

• xTool RA2 Pro roller mode — same unit, swap to roller cradle.
• Generic Y-axis roller rotaries — $40–$80 on AliExpress; useful for tumblers; mediocre on tapered or odd stock.
• Ortur YRR 2.0 — solid value roller.

Galvo / fiber rotaries (small, indexed)

• ★ OMTech / Cloudray fiber chuck rotary — small-format chuck for ring engraving on fiber-galvo. Pairs with EZCAD2 / LightBurn Galvo.
• Cloudray GP Pen rotary — for cylindrical pens, lipsticks.
• Indexed rotary jigs (3D-printed Thingiverse) — DIY for very specific objects.

Specialty rotaries

• Knife / blade jaw rotary — clamps blades for hunting-knife work; fiber rotaries from Cloudray or DIY.
• Sphere / egg rotaries — niche; xTool RA2 Pro and a few specialty rigs handle eggs.
• Wine bottle rotary — long-bed roller variant; supports the bottle along its length.
• Glassware jigs — rotary + masking + dish soap (community technique on glasses).

Why rotaries fail (and how)

• Slip on roller designs — heavy + tapered stock slips; chuck or 4-jaw fixes it.
• Axis-step calibration drift — re-measure circumference and re-set steps/mm in LightBurn rotary setup whenever you change jigs.
• Z-focus drift across the cylinder — pin focus to top of cylinder; lower the laser between passes for big diameter changes.
• Rotation backlash — chuck rotaries have very little; rollers have lots; account for it on dense raster engraves.

Pick this if…

• Default consumer rotary, "does everything": xTool RA2 Pro.
• Best accuracy for ring / cylinder on fiber: Cloudray FDA chuck.
• Cheap "engrave a tumbler today": any roller rotary, ~$50.
• Knife blades / oddball stock: 4-jaw chuck rotary.
• Wine bottles or long bottles: dedicated long-bed roller rotary.
