Sculpfun S30 Ultra + 20oz Classic Tapered Tumbler Rotary Setup Guide
Pre-configured engineering parameters for engraving the 20oz Classic Tapered Tumbler on the Sculpfun S30 Ultra. Follow the pre-calculated chuck positions, tilt angle, and optical focus settings below.
Tapered Tumbler Rotary Tilt-Angle & Warp Template Generator
Preset: 20oz Classic Tapered Tumbler (Tumbler)
Tilt your rotary chuck or elevate the roller tailstock by exactly 2.9°. This guarantees the cup's outer engraving surface sits 100% parallel to the laser lens gantry throughout the rotation.
Enter this diameter in LightBurn's Rotary Setup when engraving an isolated logo without full conical warping.
Tilt rotary chuck or elevate roller tailstock by 2.9° so the top rim and body remain coplanar with laser nozzle.

Sculpfun S30 Ultra + 20oz Classic Tapered Tumbler Setup FAQs
Q1: How do I mount and level the 20oz Classic Tapered Tumbler in the Sculpfun S30 Ultra?
For the Sculpfun S30 Ultra: 1) Ensure any necessary riser base or honeycomb removal is completed to allow clearance for 87mm diameter drinkware. 2) Insert the 20oz Classic Tapered Tumbler into the rotary fixture using Step 2 (70-100mm Jaw Position). 3) Adjust the leveling tilt angle to exactly 2.9° so the top rim and bottom base remain coplanar with the Sculpfun S30 Ultra's laser nozzle.
Q2: What diameter and steps-per-rotation do I enter in LightBurn for this pairing?
In LightBurn Tools > Rotary Setup: Set steps-per-rotation to 2560 (or check $101=80). If engraving a small front logo, enter 78.50mm into the cylinder diameter field. If wrapping a 360° graphic, use our downloadable SVG generator for true conical warp.
Q3: Will the 20oz Classic Tapered Tumbler clear the laser gantry or housing on the Sculpfun S30 Ultra?
The 20oz Classic Tapered Tumbler has a maximum outer diameter of 87mm and height of 168mm. Verify that any handle or mug curve clears the laser nozzle during a 360° dry framing run before firing the laser.
Q4: How do I focus the Sculpfun S30 Ultra on the 20oz Classic Tapered Tumbler?
Focus the 40mm lens directly onto the apex (top tangent point) of the 20oz Classic Tapered Tumbler after leveling it by 2.9°. Loosen brass thumbscrew on Z-carrier and slide laser head down to acrylic focal column.
