Our little polymer housings used to sit square in the jaws. Now each awkward tray earns another pickup edit. The tray looks stationary, which is a wonderfully cheap measurement. What should I ask maintenance to inspect before somebody decides the arm has lost its manners?
Maintenance found a loose contact insert during inspection. The intended assembly is being checked before restoration. We have kept the current program and previous edits.
Once it's restored, compare those edits against the proper tool setup. Otherwise you can repair the hardware and keep all the little compensations it inspired.
The toolmaker is reviewing the mounting and maintenance method. I do not have a cause yet. Pickup verification waits for the restored assembly and agreed program review.
