Function: These commands position the tool.
G0 travels on a line to the defined position. As opposed to G1, G0 elements are not modified by path preprocessing like tool radius compensation and angle smoothing/rounding.
G92 sets the position suddenly. The result is that a jump is also executed on the axes. If MC_ControlAxisByPos.bAvoidGaps:=TRUE is set, then a jump is not executed. Instead, all axes are traveled individually to the target position in the shortest distance. G92 can be inserted before the first traveling element in order to set the start position.
In a series of G92 commands, the last one is executed first. The previous ones are skipped. If a G1 block with identical coordinates is inserted, then the jump is executed for one cycle. This is an advantage if the path between the positions of the jump commands is not important, but the specified position should be traveled as fast as possible. The SMC_ControlAxisByPos* function blocks detect a jump to the specified values, pause the interpolator, and interpolate each axis individually as fast as possible.

Description |
|
X Y Z |
Target positions of the Cartesian axes |
|
A B C P Q U V W |
Target positions of the additional axes |
|
E |
Path acceleration/deceleration |
|
EF |
Path acceleration/deceleration only for G0 motion. If is set EF <> 0, then the value that is defined in E is not taken into consideration for G0 movements. |
|
F |
Path velocity |
|
FF |
Velocity that is used only for G0 movements. If is set FF <> 0, then the value that is defined in F is not taken into consideration for G0 movements. |
|
H L/O |
H function |
|
S |
S profile |
Graphical representation
In the graphical editor, G0 commands are represented by a green line. G92 commands are not represented directly. They simply move the start point of the subsequent element. Positioning commands can be inserted in the CNC text editor or in the table editor only. They can be move in the graphical editor.
Examples
Positioning with linear interpolation with defined feed
N0 G92 X10 Y10 (set the start position to 10/10)
N10 G1 X20 F10 (line interpolation to 20/10 with feed 10)
N20 G0 Y20 F100 (line positioning to 20/20 with feed 100)
Different positioning modes
N0 G92 X100 Y100 F100 (set the position to 100/100)
N10 G1 X100 Y100 (holds the output of this position for one cycle)
N20 G92 X50 Y100 (set the position tangential to 50/100)
Positioning with defined path velocity
N1 G0 X1000 Y0 FF1000 EF10000 EF-10000 (positioning with velocity 1000)
N2 G1 Y100 F100 E100 E-100 (interpolating positioning with velocity 100)
N3 G0 X0 Y0 (positioning with velocity 1000)
N4 G0 X1000 FF0 EF0 (positioning with velocity 100 because FF and FE are reset; in this way the values are used in F and E)
