The XCS file has two Layers using different settings. First, there's a blue light layer, which makes the initial engraving on the tumbler, followed by an IR layer, to clean up the image. Each layer is set for a single pass, but multiple passes will be needed, depending upon the thickness of the powder coat. The Hydrapeak 40oz tumbler was purchased at Marshalls for ~$20 and has a thicker powder coat, thereby requiring three passes. The project picture shows the tumbler after two passes. If using the xTool Purple-to-silver, Stainless Steel Tumbler, with handle (item TU033. TU034, or TU035) you might be able to get away with only two passes. 

Use the settings provided and ensure to process by layer, so the blue light goes first, followed by the IR clean-up pass. Also, feel free to adjust the number of passes, so you don't have to re-process the project multiple times.
