Our UR5e housing starts flat and lifts at the first finger contact

I've got a clear view of our housing sitting flat in its source fixture, then one corner lifts as the UR5e fingers close. The saved pickup edits keep growing. What should maintenance compare on the actual tool before we keep another one?

Keep the identified housing, fixture and fitted finger assembly with those saved versions, then compare the intended support, pad contacts and mounting during the maintenance check; the first-contact view is useful, but does not identify the cause by itself.

Maintenance has the actual pieces and versions. One finger sits visibly farther forward on its carrier. I'm not sure whether that's intended; the spare in stores only has a general description.

Get the intended assembly drawing before blaming the offset. Check the mounting faces and locating features as well as the pads; a correctly named finger can still be fitted incorrectly.

Toolmaker supplied the drawing. The fingers should be a matched arrangement here. Maintenance is checking why the fitted positions differ; no new point edit.

We had a change called like-for-like where the contact geometry changed but the stores description didn't. Keep the actual part references with the drawing, Rebecca. A bag saying housing fingers is not much of a comparison.

And retain what is fitted before parts are swapped; the general spare description is not its identity.

Fitted references match the intended pair. Maintenance found one finger's locating shoulder wasn't fully home on its carrier after the earlier change. The pair is retained while they correct the mounting and review the pickup edits.

Have the reviewed pickup compared with the restored mechanical arrangement before returning to the full transfer, including the receiving tray and release; an edit made around the misplaced finger should not become permanent merely because the finger is now seated.

Which circulating trays are in that return check? One convenient pocket won't cover a whole shift's handover.

All three identified trays used on this housing job. Tool mounting corrected; controls has separated the accumulated pickup edits from the intended setup. The combined return check is scheduled, not completed.

Will the person doing the next finger change be able to tell the shoulder is home, Rebecca? Otherwise the useful finding stays in maintenance's memory instead of the changeover.

The seating face can be inspected during the proper changeover check. Maintenance has added a view of that actual shoulder to the instruction. No relying on the outside position alone.

Did the combined return check stop the lift?

Yes. The housing stayed flat through closure in the completed check, and transfer and release passed on the three identified trays. We used the reviewed pickup version with the corrected mounting, not the last compensating edit.

What did you do with the old edited versions? They can be useful history without remaining somebody's tempting shortcut back to the previous setup.

Archived with their reasons and the fault report. The active job points to the verified version. Thanks Daniel; the operator's folder had both old and current copies before we cleaned up that selection.

Keep the mounting finding with that version decision so a later reader can see why the compensation was removed, rather than interpret the restored points as an unexplained preference.

And did stores sort the spare description, or is the next order still going to be for housing fingers?

Stores now lists the matched finger references and carrier arrangement. Covering technician completed the revised changeover walkthrough. We have a repair, a checked transfer and a usable handover now, rather than another note to watch it.

Any further pickup nudges since that handover?
