#[ #161 + 6 ]= 0.2
#161= 556 (START CALIBRATION VARIABLE)
This value (0.2) is NOT an absolute distance but a factor - a smaller factor reduces the back-off distance.
I would strongly suggest NOT changing the base variable from 556 as you may conflict with the tool setter variables!!!
If you intend to fix the factor, it is probably best to recalibrate also just in case. (though metrology wise the back-off shouldn't affect performance)
