Not just to be contrary I use the upper left corner of the vise.
However, I do admit the upper right is more logical. For Z my travel so
short I don't worry about reaching the bed.

Gentlemen,
I always set up my machines with the home position at the -
X positive limit (or close)
Y positive limit (or close)
Z positive limit (or close).
This gives me all negative values in the work piece offset registers.
Z up is the most important to me. If I tell it to go home (G91G28Z0) I want
the tool to be as far up as possible. This way the tool should never plunge
into the table or work piece.
I have a tendency to use the X positive side of the solid vice jaw as X
zero also. On occasion I will use the X negative side of the solid vice jaw
but not often. This gives me all negative values (or nearly so) in the
program. This gives almost all negative values for X and Y and make it (for
me) easier to read the program. The machine doesn't care which way the
program looks.
thanks
Stuart
