Intermittent stops while handling a rigid plastic housing: what should I capture?

Our imported package uses Universal Robots UR5e for fixture unloading with a rigid plastic housing in a small parts assembly workshop. It stops intermittently. I've been waiting 51 days since reporting it to the unnamed seller we bought from through Alibaba. I sent a phone video; they asked for more information. Fair, but what would actually help?

Have you captured the exact alarm before restarting? Also, does the stop happen before release, during it, or after it?

@LinBrooks0792 I now have the alarm indicating a missing process confirmation. Reviewing the unedited video places the wait before release, so my original description of a dropped workpiece was inaccurate.

Send a corrected description supported by the exact alarm, full recording and installed version details. Ask support to identify the expected confirmation and assign responsibility for the next diagnostic action.

@LinBrooks0792 Should I preserve the original report when I correct it? Removing that wording might make it difficult to understand why support's existing replies focused on a drop.

@BethAdams0150 Leave the original account readable and add the correction prominently. Explaining that the unedited recording shows a wait before release gives support a reason to revise its diagnostic focus.

@LinBrooks0792 My own support case stalled because the robot and gripper contacts each expected the other to arrange the test. A named coordinator clarified who would organise the next action.

Our correspondence shows a similar coordination gap. Both contacts refer me back to the other's response, and I can't find an assigned owner for the test.

That missing confirmation points to the gripper, so its contact should take the diagnostic lead.

You're jumping from a missing signal to a failed component. It could be the interface or sequence. The alarm doesn't assign ownership by itself.

@TheoAli0236 I was too definite about the source. The package seller should coordinate investigation of the missing confirmation through the interface and bring in the relevant contacts without assuming a component has failed.

When you say the seller should coordinate this, do you mean Alibaba or the business that supplied the package through the marketplace?
