Machine is a Hitachi Seiki HG 500 with Fanuc 18 I. I'm wondering if there is a parameter setting to change machine behavior when G43 is called . All of my tools are set with positive offsets. After a tool change the machine alarms Z Axis overtravel because the machine wants to move in the positive Z by the tool offset amount but it is already at the Z home position where the tool change occurs. When I apply a G43 positive H the machine moves in the positive Z by that amount so the Z position on the screen will remain the same. What I need is the axis not to move and just change my z valve by the offset amount once G43 is applied. Thanks
