We keep nudging pickup points when our Fairino FR10 setup gets unreliable at tray unloading with a rigid spacer block in a small assembly handling cell. The tray looks like it's in the same place, but the grip seems less square. I'm suspicious of all these tweaks.
What should I inspect before blaming the arm or reteaching everything?
Keep a copy of the current configuration and hold off on further coordinate changes. Under the appropriate isolation procedure, maintenance can use the observed rotation to focus inspection on tooling contact, mounting and tray seating.
@ZaraAdams0134 Agreed, I called it too early. Treat the replacement as a lead; verify installation and contact condition alongside tray location before assigning the cause.
