an incremental move, the ending point is defined relative to the current tool location. The G90/G91 commands tell the system which of these two modes to use (described below).
While there will be cases where incremental programming is useful, generally you should define your moves as absolute since it is a less error prone method of programming. All of the examples in the following section use absolute positioning unless otherwise noted.

G00 Rapid Tool Positioning
The G00 command moves the tool to the designated XYZ coordinate at the rapid rate using
Example: |
|
G00 X1.0 Y2.0 Z1.5 | Moves the tool directly to the Program |
| Coordinate X=1.0, Y=2.0, Z=1.5 at the rapid |
| rate (assuming G90 is active). If G91 is |
| active then it moves the tool a distance 1, 2, |
| 1.5 from the current location. |
When using G00, there are several things to keep in mind:
∙You do not need to specify all three coordinates, only the ones for which you want movement.
Example: |
|
G00 X4.0 Y3.0 | Moves the tool to Program |
| coordinate X=4.0, Y=3.0, leaving the |
| Z position unchanged. |
∙This is a modal command, meaning that all successive moves will be treated as rapid moves until another modal move command (G01, G02 or G03) occurs.
Example: |
|
|
G00 X1.0 Y2.0 Z1.5 | Rapid Move | |
X4.0 | Y6.5 Z1.0 | Rapid Move |
G01 X3.0 Y3.0 Z1.4 | Feedrate Move | |
X2.8 | Y1.4 Z0 | Feedrate Move |
∙The interpretation of the coordinates depends on the G90/G91 command in effect.
