Time to bring your design to life.
4.1 Click “Projects” → “SD Card”
From the home screen, tap “Projects” and then select “SD Card” to access files saved to your machine.
4.2 Select the Mickey Mouse Engraving Picture
Pick the image file of Mickey Mouse you’ve already uploaded. If you haven't yet transferred the file, do so using LightBurn or another design program, then save it in GCode format onto the SD card.
4.3 Set the Engraving Parameters
Here’s where it gets technical. For a metal-coated tumbler, use the following parameters for optimal results:
Fill-Speed: 4000 mm/min
Power: 100%
Line Interval: 0.1 mm
Passes: 1
These settings strike a balance between detail and safety, ensuring that the laser burns just enough to strip the coating without damaging the base metal.
4.4 Adjust the Image Size
Scale the image to match the flat engraving area of your tumbler. Typically, a space of about 60mm x 90mm works well. Make sure the design fits proportionally and doesn’t wrap too far around the curve of the cup.
4.5 Click the Frame Button to View the Engraving Area
Use the “Frame” feature to preview where the laser will engrave. The laser head will trace the outline, allowing you to make sure everything is centered. Adjust your tumbler on the RR2 if needed.
