If you want all of the images engraved on the slate coasters, place the 4 blank slate pieces onto the bed of your xtool.  Automeasure the slate coasters.  Then mark the processing area (the golf flag image).  Make sure to mark each of the slate and move the images into the area for each slate.  If you want to just pick one or two of the designs, recommend that you open another canvas and copy the images you want.  Make sure that you mirror the settings in the new canvas.

Check the engraving field by pressing the framing box on the bottom right.  Make sure it covers the area the slates are in.  Then process.  Enjoy them!
