Hey Darryl, it did etch into the wood. As a matter of fact I ran it through my drum sander to clean it up a little.
I bought the mount J Tech offered for the X-carve but didn't like the fact it wasn't easily removable. I based my mount design on Shane Bell's.
I can install or remove the mount in seconds. I use GRBL and GRBL shield. I do not have an x-controller. I really like the J Tech product.
