Probe not in correct location

I am having a problem with a probe not going to the right place. Usually I requalify making sure the sphere is the correct one, and all x y z values make sense. In this case we have an XXT head on an O inspect. Master probe is roughly 28 mm to center of ball. The probe in question is an L probe whith a 50 mm extension in the Z - direction, and 44mm in the X- direction.

This is my second day at this company so I don't know a lot of the background info. We ran the base alignment and the first probe goes right to the correct spot. It does a probe change to the L probe I just described, and the probe does not come down to the correct z coordinate. The probe is off roughly 70ish mm too high in Z.

I zerified the correct ball is used, located the sphere with the master, and qualified with the correct sphere. Everything seems like it should be working, except that it goes too high in Zbefore coming in from the X+ plane.

Any thoughts or simple things I might have missed would be welcome.

We have run the base alignment over again, and like I said the first probe finds everything just fine which makes me think the problem is within the L probe qualifications.

When you open the feature that is measured with the L stylus, does the feature and/or strategy look likes it's in the right place on the screen? Are you working from a model, or did you create the feature in the "teach" mode? If teach mode, did you create the feature using the L probe but the 1 -Z stylus was active? If so, just re-create the feature with the L probe.

Everything looks good here. Select the L stylus and take a manual point on the part. Check to see if point is on the model where you probed it. I'm guessing it might not be. If that's the case, you may have to completely scrap your base alignment and re-create it with new features. Try taking a point with the down probe, too.

Do you recall doing any "out of the normal routine" steps during the creation of the base alignment?

I will check that, but the L stylus looks like it is in the part if you show probe object. I didnt create any part of this program. This is a validated program created by an outside company. This is only my second day and production is yelling "HELP. We don't know what happened. If it was base alignment I would have expected the other stylus system to not find features either. Its a t stylus with the Z- picking up base alignment. The other stylus tips on that t find their features. If I do a new base alignment, which it looks like I might have to do, program needs to go through Gage R and R all over. Im ok with that being the case, but trying to avoid it if possible.

Open the editor from the circled entity.
Then select the stylus geometry.
(Not at my PC, so I am recalling names of dialogs).
Screen shot the geometry and post it, its similar to the image you provided.

Then make a circle feature on your reference sphere with a known good probe.
Then do the same with the L probe.
Post the Z values of each.
