I am just a hobbyist with some pricey “toys” and not technically a business. I have had the xcarve earn back it’s initial investment from a couple of jobs plus a bit of pocket "fun " money .
The biggest was featured here in a blog post that some may remember,

And a I also used it to add an enhancement that would have been difficult otherwise to a couple of items that were custom built one of which sold to a nice profit and was commissioned specifically because of my ability to inlay and engrave accurately into wood.
