The normal way to set these variables is through the Gcode commands
to set a work offset. That is G10 L2 P{n} where n is a number from
1 to 9 and corresponds to G54, G55, G56, G57, G58, G59, G59.1, G59.2
and G59.3

Generally, it is easiest and most goof-proof to move the machine to the
desired reference point, and then enter G10 L2 P5 <enter>
to make that location be the (0,0,0) point for the corresponding G5n
offset. You can also provide an offset in the G10 command, like
G10 L2 P5 X1.234 Y0.123, but this seems more prone to errors,
at least when setting things up manually.
