.8MM Stylus checking a 1.0MM hole Clearance Clarence...

[[Je...]]

First is there a setting, utility, plan...something to direct the stylus to approach and retract from the center of a circle when scanning a circle? Because this makes perfect sense...

If not, my clearance data is at -.8MM and still off center. So negatives don't work. 

 

Thanks.

set your clearance distance to 0 and retract distance to .1

Retract distance is the distance off the wall for a cylinder, and it is based on ball center. So Retract=( Radius of the hole-Radius of the probe) should put it right down the middle, if the hole is at nominal position (A system cant adjust to a position that it doesn't know yet, so it has to run to the nominal). As Dustin indicated, 0.1 for retract in this case
