OmTech Polar 350 + Glencairn Whiskey Glass Rotary Setup Guide
Pre-configured engineering parameters for engraving the Glencairn Whiskey Glass on the OmTech Polar 350. Follow the pre-calculated chuck positions, tilt angle, and optical focus settings below.
Tapered Tumbler Rotary Tilt-Angle & Warp Template Generator
Preset: Glencairn Whiskey Glass (Glass)
Tilt your rotary chuck or elevate the roller tailstock by exactly -8.75°. 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.
Extreme 8.75° reverse taper (flares out towards waist). Requires gentle clamping to prevent thin crystal shattering.

OmTech Polar 350 + Glencairn Whiskey Glass Setup FAQs
Q1: How do I mount and level the Glencairn Whiskey Glass in the OmTech Polar 350?
For the OmTech Polar 350: 1) Ensure any necessary riser base or honeycomb removal is completed to allow clearance for 46mm diameter drinkware. 2) Insert the Glencairn Whiskey Glass into the rotary fixture using Step 1 (Internal Narrow Rim Grip). 3) Adjust the leveling tilt angle to exactly 8.75° so the top rim and bottom base remain coplanar with the OmTech Polar 350'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 12800 (or check $101=100). If engraving a small front logo, enter 56.00mm into the cylinder diameter field. If wrapping a 360° graphic, use our downloadable SVG generator for true conical warp.
Q3: Will the Glencairn Whiskey Glass clear the laser gantry or housing on the OmTech Polar 350?
The Glencairn Whiskey Glass has a maximum outer diameter of 66mm and height of 65mm. 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 OmTech Polar 350 on the Glencairn Whiskey Glass?
Focus the 50.8mm lens directly onto the apex (top tangent point) of the Glencairn Whiskey Glass after leveling it by 8.75°. Use built-in acrylic step gauge between lens nozzle tip and highest point of cylinder.
