Description:
G49: tool length compensation off
G43: compensation along positive direction (end point value of compensation axis adds offset
value)
G44: compensation along negative direction (end point value of compensation axis subtracts
offset value)
H_: parameter of G43/G44, i.e. tool length compensation offset no. (H00~H07), denotes length
compensation value relative to the tool compensation list.
Tool length compensation is used to compensate the deviation of tool length, which subtracts or
adds the saved tool offset value from or to the command value of Z-axis.
G43 and G44 are modal commands. When G43 or G44 is programmed, they will be always
effective until G49 command appears to cancel them.
