Reference point return (G28, G29, G30)
These commands allow the machine to be commanded to a fixed point (reference point) by first
passing through an intermediate point on the way to the reference point. First a fixed reference
point in XYZ is entered via the front panel into the reference point parameters. The reference
point is relative to machine zero. Once this point is established it will remain unchanged until
replaced by another front panel command. Each time a G28 or G30 is commanded it will return
the machine to the designated reference point. Positioning to the intermediate and reference
points are done in rapid traverse. If a G28 or G30 is executed with no axis definitions it has no
effect. If one or two axes are commanded as intermediate points, only the commanded axis will
move to the intermediate point and reference point. Once an intermediate point is programmed, it
will be remembered until the next G28 is executed (i.e. for use in a G29).
The command format is as follows.

Y 0
