My UR5e fixture-to-tray transfer has become unreliable. We keep nudging pickup positions on the shared tray station. The rigid spacer sits less square in the gripper, although the tray looks unchanged. What physical comparison should come before another program edit?
An apparently unchanged tray does not exclude seating or contamination at its locating surfaces. Have maintenance inspect the secured setup under the applicable isolation procedure before using the program to compensate.
I would resist turning this into a complete strip-down immediately. Photograph the assembled condition and compare accessible reference features first, within your inspection procedure. Dismantling everything can remove the thing you wanted to understand.
That is reasonable. I meant a controlled inspection, not dismantling by default. The as-found condition is particularly important when several small program adjustments have already accumulated.
The spacer looks angled against the fingers. I cannot yet say the tool itself changed angle. The tray comparison has only been visual, with no reference measurement.
Reece's comparison is useful only if the old piece is still representative. A convenient undamaged sample can miss current size or surface variation. I would include actual current pieces, without treating either group as proof on its own.
Use the specified part and tooling requirements as the reference, then record what the current assembly shows. Photographs can explain the contact pattern but cannot by themselves establish every relevant dimension.
I can recover the edits, but the reason notes are poor. Maintenance has the as-found inspection request. There is not enough evidence yet to call the fingers worn.
Please include any permitted cleaning or adjustment in the record when it happens. If the next comparison changes, knowing what was touched matters more than everybody agreeing that the setup now looks better.
