G28: Move to Reference Point
The axes first move to the specified center point and then to the 1st reference point (home position). For accurate movement to the correct point, the axes must be sent to the reference.

G28: 1. Reference point movement command
X: X position to move to before reaching the reference point
Y: Y position to move to before reaching the reference point
Z: Z position to move to before reaching the reference point
A/B/C: A/B/C position to move to before reaching the reference point
U/V/W: U/V/W position to move to before reaching the reference point
If an axis code is specified in the command, that specific axis or axes will move. If no axis command is added to the G28 command, all defined axes in the machine will move. In incremental mode, if the target value for an axis is specified as 0, the machine will move directly to the reference point.
