I have one faceplate in two training pictures, with a bright stripe in different places. Both say scratch. Should I keep it out of the proposed UR5e reference set until someone judges the part?
Not yet. I've identified the plate and removed both guesses from the training handout. Thank you; keeping the source material makes more sense than deleting the confusing pictures.
Thomas's question is worth checking alongside the physical inspection. We have just seen a plate rock on an unintended holder contact. That can change the image without answering whether the surface is acceptable.
I'd get that holder question settled before buying another lamp, though exploratory lighting pictures can still be useful if nobody quietly calls them the approved inspection method.
Our fixture designer has the samples and drawing range. Quality accepted the original plate's surface. Holder revision still pending, with a confirmed reject selected for the eventual lighting comparison.
Include the person who will load it in that comparison. A holder that works only when its designer settles the edge carefully is not the repeatable presentation your lesson needs.
