Laser Engraving Tumblers and Cups: Rotary Attachment Setup and Settings

Engraving tumblers is one of the most popular and profitable applications for a diode laser. This guide covers setup, settings, and troubleshooting.

Equipment

• Diode laser with rotary support (xTool, Longer Ray5, SCULPFUN, Atomstack)
• Roller rotary ($30–80) — great for straight tumblers
• Chuck rotary ($80–200) — better for tapered mugs and Stanley cups
• LightBurn software

Physical Setup

1. Connect rotary to the Y-axis port on your laser controller
2. Place tumbler in roller groove — it should sit without tilting
3. Adjust roller spacing to support at least 40% of the circumference
4. Refocus the laser on TOP of the tumbler — do not use your flat-surface focus height

LightBurn Configuration

Tools → Rotary Setup → Enable Rotary → select type → enter roller diameter (measure with calipers) and tumbler diameter.

Calibrate: With rotary enabled, jog Y 360mm. The tumbler should rotate exactly once. Adjust Steps Per Rotation until correct.

Enable Bidirectional fill for engravings that wrap the cylinder.

Settings by Material

Anodized Aluminum (Stanley, YETI-style) No spray needed. Laser removes the anodizing to expose bare aluminum.

• Speed: 2000–4000mm/min, Power: 40–60%, Lines/cm: 100

Stainless Steel Requires marking spray (Cermark, Brilliance, or dry moly lube).

1. Clean with IPA. Apply thin even coat. Let dry 2–5 min.
2. Engrave: 800–1500mm/min, 80–100% power, 100–150 lines/cm
3. Wipe off residue to reveal permanent mark.

Powder-Coated Cups Results vary. Test on the bottom first.

• Speed: 2500mm/min, Power: 50–70%

Wood Tumblers

• Speed: 4000–6000mm/min, Power: 25–40%

Centering Your Design

1. Mark center of tumbler with tape and pen
2. Use LightBurn Frame function to preview laser path position
3. Adjust X for centering, measure from bottom to desired design height for Y offset

Common Problems

• Slipping on rollers → Clean rollers with IPA
• Uneven depth/banding → Check tumbler is perfectly level
• Blurry on tapered cups → Use a chuck rotary
• Design stretched/squished → Re-enter exact diameter and redo step calibration
