Our tray-locating change still needs an honest assessment (Fairino FR10)

I added a tray locator to our Fairino FR10 setup for tray-to-fixture transfer with a small plastic sleeve in a shared assembly workshop. 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.

Was the replacement tray fully seated when that miss happened? Check that observation before assuming the locator or taught point needs another change.

@AlexAbbott0037 It wasn't fully seated. The locator reduced visible movement, but it didn't stop us leaving the tray short of its seat.

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.

@AlexAbbott0037 Does 'improved but incomplete' sound evasive? I worry people will read it as me dressing up a failure.

@ThomasBrooks0799 My separate fixture trial improved one condition without resolving changeover. Describing the remaining failure directly communicated more than forcing the whole result into a success-or-failure label.

Since the locator reduced movement, you could describe that fix as complete and list seating as a separate operator issue.

@AlexAbbott0037 That's a convenient split. The original problem was missed pickups, and ordinary replacement still produces one. You haven't established that seating is simply an operator issue.

@DineshBaker0473 You're right; that label would overstate it and blame the operator. Describe the locator's observed benefit and the unresolved seating process together as an incomplete handling improvement.

@AlexAbbott0037 The tool and program were held constant during the locator trial. That helps interpret the observed change, but the limited supervised sample still constrains the conclusion.

If those stayed the same, doesn't that prove the locator helped? I'm not sure why the sample size changes that bit.

@SarahAllen0328 It strengthens the comparison. It doesn't establish how reliably your complete setup handles normal variation and tray changes, which is the larger claim you're deciding whether to make.

@AlexAbbott0037 I've settled how to report it: less movement, but an incomplete-seating miss still matters. Any 'fixed' claim depends on reviewed seating checks and supervised replacement results.

@ThomasBrooks0799 Your reporting decision preserves the observed benefit while making the required evidence for a broader fix explicit.
