Step 1: Prepare and test the engraving
Place your material and adjust the head height using the guide provided with the laser.
Connect the Yumi L-A4 laser.
Perform an engraving test.
Position the laser head so that it is positioned on the material , keeping in mind that the engraving will start from the bottom left corner .
Start the burning test.
The ideal settings are those that produce a black, clean, and uniform engraving—without burning or pitting. Consider noting them down for future use.
Step 2: Start the final engraving
Enter the optimal parameters you obtained previously, as well as the dimensions.
Place the cork disc on the edge of the honeycomb grid and position the head at the correct height using the guide.
If you do not have one, use the button located to the right of the planet and place the head approximately in the center of the disc .
Perform a perimeter test to verify correct positioning: the beam should just touch the outer edges of the cork disc, without going outside of them. If it's not perfect, move the head until you get an ideal result.
The result: a unique cork coaster
