Can we stop nudging this pickup now?

Saved it. Maintenance found wear on one finger, but the mounting checks were fine

Compare the contact surfaces and part seating before deciding the wear explains the skew. Also note which sleeve and tray were involved, so the post-maintenance check can use an identified example.

Same sleeve leans in one pocket but not the next. That complicates the finger theory

It suggests the pocket deserves inspection too. The finger wear can be real without being the only contributor. Have maintenance compare the suspect pocket and the locating surfaces.

Can you compare that pocket with the same position on another identified tray? A static seating comparison should help before any further teaching changes.

Yes, using the agreed inspection procedure. Record whether the sleeve leans before the fingers contact it; that separates part presentation from what happens during gripping.

Was that lean visible before closing, or are we guessing from the finished grip?

Before closing. Maintenance did the comparison with the tool clear. Pocket has a damaged insert

Right, then you've got something better than 'robot seems off' to work with.

Don't forget the worn finger while everyone celebrates the pocket. You found two things. Check both, then verify the setup as a whole. One satisfying explanation doesn't make the other observation disappear.

Agreed. The repair plan should address both observations, with the responsible person reviewing any teaching changes that may have compensated for them.

Both in the work order. Tray insert replaced; finger service and setup check still pending

Leave the return-to-use decision with that final check. The next shift will need the approved tool and program combination, not only a list of parts that were replaced.
