Made a lion image with AI for engraving on a slate coaster.
Open the file in Xtool Studio.
This was the original image I used.
I inverted the image (the XCS file comes with the image already inverted)
You can find invert in EDIT-ADJUSTMENTS
I adjusted the contrast and sharpness a little bit
I made a test grid on a coaster to find the settings that looked the best.
Not all coasters are created equal ;)
Setting I used are also in the file.
Frame the lion on your coaster, my coaster was 10x10cm.
Adjust the size if your coaster is different.
Start the job, ans 4 minutes later you haave your engraved coaster.
