Range
--2450000.00000 to 2450000.00000 mm
or
--100000.00000 to 100000.00000 in.
Notes
For example, the home position for the lathe axis that moves toward the
chuck (typically called the Z axis) is usually at the opposite end of travel
from the chuck. A high positive value entered here as the home position
coordinate would result in the chuck face having a coordinate value at or
near zero.
This parameter is not used for systems that use distance coded marker
linear feedback devices.
This parameter must be set independently for each axis.
