Clearance and Retract Issue

[[ZE...]]

I am having an issue with the probe coming in to measure a plane and it is contacting the adjacent plane on entry. Is there a way to shift the probe over in X then shift back to measure. It is a very tight spot and I may need a smaller probe.

Set the clearance dist. to zero and adjust the retract. I personally like using position points, but if its too tight then a smaller probe might be the only way.

You can also use points that are clear of the adjacent face first. Then check as close as you want. Put another point clear of the adj face as a final point. Since it won't be retracting between points you shouldn't make contact.

I haven't used clearance distance set to anything except zero in 10 years. Prefer to use position points for additional navigation when needed. That's probably what you are seeking here.

I would agree with the above statements. Set your default Clearance Distance to 0 (probably causing the issue) --> Extras>Settings>Measurement. 99% of the time you can fix navigation issues with Clearance Planes, Sub-Clearance Planes, and Retract Distance. I would recommend staying away from CMM position points because you can cause collisions easily if you adjust your measurement strategy. 1% of the time you will need to use Clearance Distance or CMM position. (It is always good to keep in mind that the direction of travel for a Clearance Distance will be in the direction of the feature. Prime example of this is a cylinder that is not perpendicular to a plane, thus you can input a Clearance Distance to navigate an angle stylus into the cylinder.) Hope this was helpful!
