I'm helping with an FR5 enclosure-panel loading trial. Supplier sent a vacuum trace and a picture of one steel panel on the cups. Our panels come off a stack, though.
I don't know much about separating sheets yet. What should I ask them to show on the next trial?
Our operator used to peel a second sheet off at the receiving table and carry on. Nobody thought to count that as a failed pickup because the next station got one sheet eventually.
Then we tried to automate the table and discovered how much of the separation job his hands had been doing. Ask whoever currently handles yours what they stop to fix. You'll probably get more out of that chat than the tidy demonstration. Not saying you have the same problem, but I wish we'd asked sooner.
Has anyone shown you the panel entering the nest? Our thin lids sagged at the free edge. They were single picks all right, just not a shape the next fixture liked.
Don't assume they hid a failure. Might just be someone filming the arm because that's the expensive bit. Send a little shot list: stack edge, supported panel, entry, release. Saves another round of guesswork.
