    I have not had this on a machine but years ago I had this kind of message on some computer controlled equipment I was building. It meant there was something major wrong down in the firmware somewhere. Sorry to be pessimistic but I think the minimum you need is a visit from a Haas tech with a disc containing a software reload with the maximum being a new processor board.
    An open mind is a virtue...so long as all the common sense has not leaked out.

    A "No Interrupt" alarm means that the Mocon and the CPU are not talking. Check the power supply connection in the the lower right corner of the Motion Control PCB (Located in the upper left inside the control under the sheet metal cover).

    The red wire should have 5VDC. If this 5 volts drops out you will usually get motor overheats as well (thermal switches run off of 5vdc too).

    Could be a loose connection or a low voltage power supply going bad.
