Now comes the time when we might apply a set of G92 offsets to this program.
You'll see that it is running in each case at z0. If the mill were at the zero
position, a g92 z1.0000 issued at the head of the program would shift every-
thing down an inch. You might also shift the whole pattern around in the XY
plane by adding some x and y offsets with g92. If you do this you should add a
G92.1 command just before the m2 that ends the program. If you do not, other
programs that you might run after this one will also use that g92 offset.
Furthermore it would save the g92 values when you shut down the EMC and
they will be recalled when you start up again.
