I’ve looked through a bunch of posts and just want a simple answer if it is simple. I want to engrave in a cutting board to thick for the tray so when I remove it do I need to change any settings or will my pro do that for me ? Thank you
You will not need to change your settings if you get the cutting board to within 1/2" of the laser head.
All the posts are teaching you how to get it to the correct height.

Just stack wood or something under it to make the total thickness between 1.5 inches and 2 inches.
Cut one of these from a it of scrap and you’ll nail the engrave height every time:
your ruler is pretty cool. I’m gonna’ cut one out today.
There are also a number of people selling supports on Etsy. You can opt for a svg. and make them yourself or get some plastic ones for a few dollars more.
You might also find this handy. It gives you the actual focus height. I came up with it because that was hard to determine on glass without putting tape or similar onto the surface.
