58 Section 4 System Programming

		Y=3, Z=4.5. The Machine Coordinates
		remain unchanged at X=3, Y=3, Z=0.
G29	X4 Y4 Z0	Move the X and Y axes across and the Z
		axis down to Program Coordinates X=4,
		Y=4, Z=0, Machine Coordinates X=4, Y=4,
		Z=-4.5
G01	X5 Z-1	Linear interpolation to Program Coordinates
		X=5, Y=4, Z=-1, Machine Coordinates X=5,
		Y=4, Z=-5.5
G28		Move the Z axis up and the X and Y axes
		across to the Tool Change Position, Program
		Coordinates X=2, Y=2, Z=4.5, Machine
		Coordinates X=2, Y=2, Z=0
G49		Cancel Tool Length Compensation. The Z
		axis Program Coordinate changes by -0.500,

the difference in Length Offset between the current tool (#3: 1.000) and the tool displayed in the Current Tool pull-down menu when the program first began (#1: 1.500). The new Program Coordinates are X=2, Y=2, Z=4. The Machine Coordinates remain unchanged at X=2, Y=2, Z=0. At this point the current tool should be removed from the spindle.

G52 Local Coordinate System

The G52 command defines and activates a local coordinate system that LC uses in place of your original Program Coordinates for all absolute positioning moves. The X, Y and Z parameters indicate the offset from your original Program Zero location to the origin for the local coordinate system.

For example, "G52 X1 Y2 Z-4" would activate a local coordinate system whose origin is at a distance of 1, 2, -4 from the original Program Zero.

All absolute moves are made relative to the new local coordinate system. To cancel use of the local coordinate system in the middle of a G-code file, use the command “G52 X0 Y0 Z0”.

When LC reads a G52 command, it displays a magenta dot in the Tool Path View Port showing the origin of the local coordinate system.

Note that the local coordinate system only applies to the G-code file being executed. The G52 command has no effect on the Program Zero you set before running the G-code file. LC automatically cancels the local coordinate system when it completes execution of a G-code file.
