So it occurred to me to us a laser range finder. Then lcnc would know where the table is without having to move on boot. It does not have to be accurate like to mm as I probably never have to mill to the limit switches, and even then....

So I started to look around out there, this is amazing for the price:

I would not have to drill or bond the hardware, it is so light that a microwave magnet to hold it would be overkill. Has any one done this yet? Or am I missing something fundamental that makes it a bad idea?

Thanks, Dan.
