Take a laser and mount it on the head and after getting it swept in to

Crazy enough it might just work.

That is a *wonderful* idea! Just make sure the laser pointer is mounted
really solidly.


One stage further - mount a cheap laser pointer solidly on the
target wall and permanently fix a very small mirror on the mill head
with the mirror aimed to return the laser beam to a target on the wall
close to the laser.

The mirror reflection doubles the angular sensitivity of the
setup and putting the laser on the wall keeps it safely clear of suds
and oil.
