We keep nudging pickup points when our Fairino FR5 setup gets unreliable at tray unloading with a small polymer housing in a supervised production bench.
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?
Reviewing the recording, I can see consistent seating in the checked fixture before pickup. The workpiece changes angle during gripping rather than arriving in that position.
Preserve the current settings and pause further nudges.
Have maintenance inspect finger mounting, contact surfaces and tray seating under the proper isolation procedure, using that observation to guide the checks
I've checked the maintenance history and found a pad replacement preceding the initial pickup-point correction. That establishes a relevant sequence of changes to investigate.
Agreed, I called it too early. Treat the replacement as a lead; verify installation and contact condition alongside tray location before assigning the cause
With multiple point changes already in our history, I'm unsure how to distinguish tooling and tray effects. How did you structure that comparison on your setup?
@ChenBell0616 We kept a known reference configuration and had maintenance check one condition at a time. We didn't roll back points blindly after finding wear.
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
The relationship between the initial points and the present setup hasn't been verified. I'm retaining the current configuration instead of assuming the original positions would restore a known condition.
