I checked the Picomotor log and there is evidence that it was working properly on 06/25/2021 at about 8:45am.
Based on the log, we think it was corrupted between 6/25 and 7/5.

Next, I smelled a smell from the broken Picomotor driver and decided to disassemble it to check it out instead of sending it in for repair.

The left side pin of the two DC jacks that are not in use is bent.
The left side of the DC connector shows signs of having been burned near its base.
Based on the above, it is highly likely that the DC connector was deformed, or that a capacitor or resistor at the root of the DC connector was burned.
