We keep nudging pickup points when our Fairino FR10 setup gets unreliable at fixture-to-tray transfer with a molded plastic sleeve 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?
Look at the relationship between the workpiece and fixture before contact, then during gripping. Can your existing observations show when the change in angle begins?
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.
Agreed, I called it too early. Treat the replacement as a lead; verify installation and contact condition alongside tray location before assigning the cause.
My separate handling setup had both worn gripping surfaces and variation in tray seating. Coordinate corrections alone gave inconsistent results because they didn't address either underlying condition.
For my setup, a documented reference configuration anchored the investigation while maintenance assessed individual conditions. Discovering wear didn't mean we automatically restored older pickup coordinates.
Only if they match the verified setup. Tooling, frames or presentation may have changed; your responsible technician should compare the configuration before any supervised validation.
I can see the angle change during gripping, but I don't have an accepted correction yet. The point tweaks are paused while the inspection work continues.
