    WAIT.
    There is more.
    The printer dashboard displays 25% completion.
    Repetier Server "thinks" it is still printing, but no commands except M105 are being sent.

    Tried starting  a different job and it did the same thing almost immediately, 2% into the job.
    Note it has been working for 2 days just fine.

    That is a race condiftion with missed ok only allwing small commands like M105. I think we have fixed it in 0.60.4 so please upgrade. Then you might register a pause of "connection timeout" as configured before continuing. To prevent these pauses you need a error free communication (try different baud rate or cable) or a firmware returning lines in ok message like Repetier-Firmware or newest Marlin (maybe still only in develeopment tree available)
