Not sure exactly how you are setting your Z height but it is usual for the Z axis DRO to be 0.0000 when the cutter touches the top surface of the work. Perhaps you could check your GCode file to see if, on the 3rd pass, there is a Z command to take the cut depth below what you are expecting.
There is a slight discrepancy between your described Z height (1.9866) and that shown in the script (1.9688) - probably just a typo but it should not be enough to damage your tooling.
