G43 and G44 are modal G codes.They are valid until another G code belonging to the same
group is used.
Warning: When the tool length offset value is changed due to a change of offset number, the offset value
changes to the new tool length offset value, the new tool length offset value is not added to the old tool length
offset value.
To cancel tool length offset, specify G49 or H0. After G49 or H0 is specified,the system
immediately cancels the offset mode.
Note: The tool length offset value corresponding to offset No.0, that is, H0 always means 0.It is impossible
to set any other tool length offset value to H0.
Example1: H1: tool length offset value is 20.0 (Tool Length Offset A)
H2: tool length offset value is 30.0
G90 G43 Z100.0 H1; Z will move to 120.0
G90 G43 Z100.0 H2; Z will move to 130.0
Example2: Offset in X and Y axes.(Tool Length Offset B)
G19 G43 H_ ; Offset in X-axis
G18 G43 H_; Offset in Y-axis
Example3: H1=-4.0(Tool length offset value)
