A small assembly handling cell: Our pickup points keep needing nudges

We keep nudging pickup points when our Fairino FR10 setup gets unreliable at tray unloading with a rigid spacer block in a small assembly handling cell. The tray looks like it's in the same place, but the grip seems less square. I'm suspicious of all these tweaks. What should I inspect before blaming the arm or reteaching everything?

Does the angle change before contact or as the fingers close? Existing footage may help you locate where things start going wrong.

In the footage, it sits consistently in the checked fixture and turns during gripping. So the crooked position isn't there at the start

Keep a copy of the current configuration and hold off on further coordinate changes. Under the appropriate isolation procedure, maintenance can use the observed rotation to focus inspection on tooling contact, mounting and tray seating.

The maintenance notes show contact pads were replaced before the first point adjustment. That's the first useful clue I've found in the history

That sounds like the pad replacement caused it. Check the installation against the specified arrangement.

Timing isn't enough to call it the cause. Check the pads, yes, but don't let one maintenance entry explain away fixture variation.

@ZaraAdams0134 Agreed, I called it too early. Treat the replacement as a lead; verify installation and contact condition alongside tray location before assigning the cause.

On my own setup, we found worn contact surfaces and inconsistent tray seating together. Fixing only the pickup point made the symptoms move around.
