Can I distinguish tray movement from a sleeve slipping in the tool?

I am comparing two recordings of our FR5 sleeve transfer. The placement is skewed in the newer one, after several pickup-point adjustments. The tray corners appear to line up with the bench marks. What should I ask maintenance to inspect before we change another point?

Check when the skew first appears. Is the sleeve square immediately after pickup?

The first clear view is halfway through transfer, and it is already tilted there. The fixture hides the actual pickup. I cannot tell from these recordings whether it was gripped that way or moved afterwards.

Then that hidden interval needs observing before the tray gets blamed.

I've added that to the inspection request. We can review the tool contact surfaces while isolated, then have the responsible technician arrange an observation of pickup under the cell's normal commissioning procedure. The current video alone cannot settle it.

Interested in what they find, especially if the old point changes were compensating for grip movement.
