> engraving things in place. That's just-about the only real use case I can see. And then, again, is the question: How much engraving in place does anyone really have to do? What are you engraving? Doors? Signs? Trophies? Well, if it is a one-off occasional thing...is the cost justified? If it is done as a business, chances are you are not going on-site to someone's home to engrave stuff. If it a rare once-in a couple of years thing, there are services that will do that for you for very little money...etc. Forget CNC, I am comparing this to a $50 router and some jigs, off-the-shelf and self made. Even as a robotics guy, I just don't see it. And I have a shop full of robots and CNC machines. To me this falls under the category of "just because you can, it doesn't mean you should".

I'm happy to be wrong...I just don't see it except for corner cases (which could be all you need for a nice business).
