Setting a tool on a lathe is generally more complicated than with a mill

Holmquist,
If your luck holds I might have a manual in the archives (VERY dusty boxes)
and if that is true then it was already old in 1990.
Siemens was already going their own way then. The cooperation was even
before that time.
I will have a look in the week.

Digikey has some other models of these sensors but it seems for my

the Detroit river. "Downriver" is a common description Detroiters use

Steve,
Interesting! Can I upgrade from 2.4.3 to 2.4.6 if I originally installed
from the LiveCD (10.04)? I currently see a bunch of potential updates
appear in the Update Manager window when I start my system, but
I was afraid to install them. If I do install them, will that get me up to

Mike,
Point well taken. Right now, I'm milling PC boards using Eagle CAD
and the pcb-gcode ULP script for Eagle. It doesn't generate oword
statements,
only simple inline G-code. So hopefully I won't run into any trouble.
On a more general note, being able to "touch off after a tool change" seems
