Section 4 System Programming 53

If the move contains positive Z movement, the machine first moves up in the Z axis and then moves across in the XY plane. If the move contains negative Z movement, the machine first moves across in the XY plane and then moves down in the Z axis.

If you want the G28 command to move only one or two axes, you can limit the movement to those axes by adding the parameters “X0”, “Y0”, or “Z0” after the G28 command. Then, LC moves only the indicated axes to their Tool Change Position coordinates. A typical use is to only raise the Z axis for a manual tool change (“G28 Z0”).

Example:

The Tool Change Position is defined as Machine Coordinate X=1, Y=1, Z=-1.

G01

G29 Return from Reference Point

The G29 command moves the tool to the designated XYZ coordinate at the rapid rate.

If the move contains positive Z movement, the machine first moves up in the Z axis and then moves across in the XY plane. If the move contains negative Z movement, the machine first moves across in the XY plane and then moves down in the Z axis.

Example:

The Tool Change Position is defined as Machine Coordinate X=1, Y=1, Z=-1.

G01 X1.5 Y2.5 Z-3 F10 Linear move to the program coordinate X=1.5, Y=2.5, Z=-3
