Dwell
G4 causes motion to stop for the specified time. The P parameter is used to specify
the time in seconds to delay. G4 causes the block to decelerate to a full stop.
The minimum delay is 0.01 seconds and the maximum is 327.67 seconds. The dwell time is performed after all
motion is stopped and M functions on the line are completed. If the P parameter is not specified, X will be used
instead. If neither P nor X is specified, the default dwell time of 0.01 seconds will be used.
Example:
G0 X1 Y1 ; rapid to X1, Y1
G4 P2.51 ; pause for 2.51 seconds
G1 X2 Y2 ; Linear move to X2, Y2
G09 - Decelerate and Stop (formerly known as Exact Stop)
G9 causes motion to decelerate to a stop and dwell for 1/100 seconds. G9 is equivalent to
G4 P0.01. G9 is not modal; it is only effective for the block in which it appears. See G61
(Modal Decelerate and Stop).
Example:
G9 G0 X1 Y1 ; rapid to X1 Y1 and stop
X2 Y2 ; continue to X2 Y2
G10 - Parameter Setting
G10 allows you to set parameters for different program operations.
Examples:
G10 P73 R.05 ; Sets the peck drilling retract amount to .05
G10 P83 R.05 ; Sets the deep drill rapid down clearance to .05
G10 P81 R15 ; Sets G81 to use M15 instead of Z movement
G10 H5 R-1.3 ; Sets tool length offset #5 to -1.3 in the offset lib.
G10 D3 R.25 ; Sets tool diameter offset #3 to .25 in the offset lib.
G17, G18, G19 - Circular Interpolation Plane Selection
G17, G18, and G19 select the plane for circular interpolation commands (G02 & G03). G17 is the default plane.
See figure under G2 and G3.
G17 is the XY plane
G18 is the ZX plane
G19 is the YZ plane
G20 - Select Inch Units
G20 selects inch units, affecting the interpretation of all subsequent dimensions and feedrates in the job file. G20
does not change the native machine units as set on the control setup menu.
