Anaheim DPJ72LC2, DPJ72LC3, DPJ72LC4 manual System Programming

54 Section 4 System Programming

G28	Rapid move in the Z axis to Machine
	Coordinate Z=-1 followed by a rapid move
	in the XY plane to Machine Coordinate
	X=1, Y=1
G29 X2 Y3 Z-2	Rapid move in the XY plane to Program
	Coordinate X=2, Y=3 followed by a rapid
	move in the Z axis to Program Coordinate
	Z=-2

When using G29, 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:
G29 X4.0 Y3.0	Moves the tool to Program Coordinates
	X=4.0, Y=3.0, leaving the Z position
	unchanged.

∙The interpretation of the coordinates depends on the G90/G91 command in effect.

G43, G44, G49, M06 Tool Change and Tool Length Compensation Commands

LC supports tool changes and tool length compensation. Tool length compensation lets LC account for differences in tool lengths, so the G-Code program can be created without regard to specific tool lengths (except for possible interference problems).

THESE COMMANDS ARE NOT FOR THE NOVICE CNC USER. WHEN NOT PROPERLY USED, TOOL LENGTH COMPENSATION CAN CRASH THE MACHINE TOOL, CAUSING SERIOUS DAMAGE TO YOUR WORKPIECE OR MACHINE TOOL.

When applying tool length compensation, LC uses the Length Offsets defined in the Tooling Setup dialog box. See “Tooling Settings” in the Initial Setup section for more information on defining your tools.

For tool length compensation to work properly, LC must know what tool is in use at all times, including the tool that’s loaded when you start running a G-Code file. Therefore, before you run a G-Code file that uses tool length compensation, you must first choose your starting tool from the Current Tool pull-down menu on the main screen.

To indicate tool changes in the G-Code file, use the M06 command as follows:

M06 Tn

where n is the tool number in the Tooling Setup dialog box.
