How do I mount and level the 20oz Classic Tapered Tumbler 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 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 OmTech Polar 350's laser nozzle.

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 78.50mm into the cylinder diameter field. If wrapping a 360° graphic, use our downloadable SVG generator for true conical warp.

Will the 20oz Classic Tapered Tumbler clear the laser gantry or housing on the OmTech Polar 350?

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.

How do I focus the OmTech Polar 350 on the 20oz Classic Tapered Tumbler?

Focus the 50.8mm lens directly onto the apex (top tangent point) of the 20oz Classic Tapered Tumbler after leveling it by 2.9°. Use built-in acrylic step gauge between lens nozzle tip and highest point of cylinder.
