How do I mount and level the 30oz Tapered Travel 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 100mm diameter drinkware. 2) Insert the 30oz Tapered Travel Tumbler into the rotary fixture using Step 3 (85-115mm Jaw Position). 3) Adjust the leveling tilt angle to exactly 3.67° 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 87.50mm into the cylinder diameter field. If wrapping a 360° graphic, use our downloadable SVG generator for true conical warp.

Will the 30oz Tapered Travel Tumbler clear the laser gantry or housing on the OmTech Polar 350?

The 30oz Tapered Travel Tumbler has a maximum outer diameter of 100mm and height of 195mm. 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 30oz Tapered Travel Tumbler?

Focus the 50.8mm lens directly onto the apex (top tangent point) of the 30oz Tapered Travel Tumbler after leveling it by 3.67°. Use built-in acrylic step gauge between lens nozzle tip and highest point of cylinder.
