Tony stopped mid-cut for no discernible reason

[Robotorium]

Jamie was using Tony, and Tony got partway through the file (did the cuts and began the fills) and then stopped midway through the fill he was on. The clock on the cut kept running, but the head stopped and the laser was no longer firing. Pausing/resuming did not change anything.

I couldn't see anything at the Lightburn end that looked amiss.

Tony has since successfully run the same file.

It feels like it was maybe a duplicate of #1742 or #1805? Although chatting to @magman2112 just now he thinks #1742 was solved a while back. If so, this is a new problem, so I'll leave it open for @DoESLiverpool/laser-maintenance to investigate/check.
