Thanks, man! You’re going to love playing with the x-carve and the learning curve won’t be as steep as you think. Especially if you start with Easel - it’s super user friendly and then once you get comfortable with speeds and materials - you can move into VCarve and other 3D softwares. Good luck - can’t wait to see what you create!
I was able to track down the files and sort of reconstruct the easel file for them. You should be able to view it here: Easel - Star Wars Coasters
You’ll definitely want to confirm speeds/depths/etc for you and your machine, but it should be pretty close. This should at least get you the art you need - the rest should be pretty straightforward.
