This command sets/displays a fixed hardware HOME location for an axis in units of millimeters. The HOME position is considered a fixed hardware location and is adjusted properly when the controller’s coordinate system is altered with the HERE or ZERO function. The HOME position is automatically remembered and recalled through a power cycle and does not need to be saved using the SAVESET command. The home position defaults to a large positive number far exceeding the mechanical limits of the system, or else with the upper limit for DAC devices including piezos, micro-mirror, and tunable lenses.

HM [axis]+ will set the home position to be the current position. Restore the default home position by executing HM [axis]-.

If there are no errors, a reply of :A is returned.

HM X?
:A X=1000.000

In the above example the default location for the HOME position for the X-axis is returned.
