I was talking to Tom Caudhill (sic??) at CandCNC the other day and he said that he has a little laser pointer mounted on his mill head. It is aimed at a vertical line on his wall 6-8 feet away. When he raises or lowers the head he just twists it back to where the laser points at the vertical line, and he is back in position within a fraction of a degree. Sounds like a pretty trick solution. I would just like to try it and see how close it is to the same x,y position.
