13. Z axis moves away from the workpiece in the positive Z direction by an offset amount The offset amount is equal to the difference in lengths between the current tool when the G43 command is executed and the previous tool LC uses the Length Offset values in the Tooling Setup dialog box to calculate the difference in lengths between two tools Example G43 H3 Shifts all subsequent Z axis moves away from the workpiece in the positive Z direction by the difference in lengths between tool number 3 and the previous tool The G44 command is identical to the G43 command except that it shifts all Z axis moves in the direction opposite from G43 Unless you are an experienced CNC programmer and know how to use G44 correctly G43 1s the preferred command The G49 command cancels tool length compensation It removes any offset that LC has applied since the G Code program began running When using tool length compensation there are several important things to keep in mind e You must predefine all tools and tool lengths in the Tooling Setup dialog box e It s good practice to include an M06 tool change and a G43 compensation command for the first tool used near the beginning of the G Code program e LC automatically cancels tool offset when it finishes processing a G Code file or during any operation that ends the current run of the G Code file such as resetting the program opening a new program and soon TO AVOID CRASHING THE MAC
