The tray locator helped, then a replacement brought back a miss

I added a tray locator to our Fairino FR5 setup for fixture-to-tray transfer with a rigid molded housing in a supervised parts transfer bench. A few supervised runs looked more consistent, then a tray replacement brought another missed pickup. I want to share the result accurately. The change seems useful, but 'fixed' feels a bit generous.

Can you establish the tray's seating condition at the unsuccessful pickup? That would help interpret the recurrence before considering another locator or coordinate revision.

The unsuccessful pickup occurred with incomplete tray seating. I can see less tray movement with the locator, but the new feature hasn't prevented incomplete insertion.

@LucyAdams0132 Your update can describe reduced movement alongside the incomplete-seating miss. Have a seating check reviewed and compare handling through routine tray replacements under supervision before making a broader success claim.

@MinaBrown0946 I'm considering describing the result as an incomplete improvement. Would that convey the evidence clearly, or might it sound as if I'm avoiding the unsuccessful result?

On my own fixture trial, both were true: steadier seating, unfinished changeover. Naming the exact remaining failure was more useful than trying to pick one cheerful or miserable label

You could call the locator fixed and leave seating as an operator issue. The mechanism did reduce movement.

@MinaBrown0946 Reduced movement doesn't resolve the reported handling problem when a normal tray replacement can still lead to a miss. Calling the remainder an operator issue assigns a cause you haven't established.

@SofiaArcher0369 I divided the result too neatly and attributed responsibility without evidence. The update should retain both the locator's observed effect and the unfinished seating process within the same handling problem.

The locator seems helpful, but the incomplete-seating miss is still part of the result. I'm reporting an improvement with the handling issue open.

@LucyAdams0132 Describing the remaining failure alongside reduced movement lets readers understand both the benefit and its current limitation.
