Strange moves before feature

[[Ja...]]

I had a quick question, and I'm sure there is a simple solution.

For a large majority of the features that I attempt to measure, I will see strange movements before and after the probe touches the part. For example, probe will move to clearance plane +Z, move above feature, come down to feature, move a little to the left, measure feature, move a little to the right, move up to +Z.

Could anybody point me in the correct direction to eliminate these seemingly unnecessary moves?

Clearance distance? This sounds a lot like something I used to see when probing a cylindrical groove from above on some of our older programs. The machine would drop down from +Z to the feature, then shift just a bit to the left before taking the points. Setting clearance distances on your features to 0 would stop that from happening.

That would be because you have Clearance Distance set to a value. Clearance Distance a value that the stylus will move to before it travels along the features normal vector.

Go to Strategy and click on Clearance group and set it to zero. Then for all future programs go to Extras/ Setting/ Measurement and set the Clearance Distance to zero and only use it when needed.

I had an idea that the answer was somewhere around there, but I wasn't sure.

I'll give that a shot. Thank you both.

You can also set default clearance distance for the software to 0 in Extras>Settings>Measurement>Travel, yeah? I've noticed Calypso doesn't like to let me set a measurement plan's default clearance distance to 0, only allowing that particular number to be set per individual feature (although highlighting every feature amounts to the same thing as plan default), but I can make 0 the default by specifying it in the Calypso settings.

This is a 6.4 version issue. Do you have the latest Service Pack?

6.4.2003, although if it got corrected in a SP release, I wouldn't have noticed, since I've had the system default clearance distance set to 0 for a while.
