    Is it saying waylube is low on the screen? If it's an older machine you have waylube pump and spindle mist oil luber. Waylube will stop machine before it's empty.

    when you say you reset. Are you saying that you do that by pressing the JOG button to reset? Or are you turning the machine off and doing a CS?

    Double check all the connectors. It sounds to me like something is just loose. Mine did the exact same thing and there was just a loose cable to the axis control board.

    Do you HAVE an A axis?

    The oil valve is on a timer. It will turn on every 10 minutes or so.

    Can you send the g code?
    Have you ran the part before?
    What year is this Machine?
    Which axis fault? X, Y, A (4th axis) or Z ?
    Can you run other parts?
    Do you have to hold the jog button to turn the power back on and move the table when the part stops?
    Do you have the space to actually cut the part? Is the tool path coming off the table and running in to the limits of the table?

    Do you have a air/oil spindle? I think you might be confusing spindle oil with way lube...

    no,the way lube is one thing and the spindle use a cooler to discipate the heat and a fan too,but the fail is not in the spindle
    the machine stops in any axis (when the fail comes)can be x,y,or z.....the spindle have a pump to refrigerate,but i change too

    This is a tough problem. I have a 1997 as well but never had a problem.

    If it is resetting on any axis I am lost. All I can suggest right now is to gain axis to the ball screws and see if there is a mechanical issue with any of the bearings. I still also have a feeling there may just be some loose wires.

    You have me stumped. I suggest an email to Independent Technology Service They have helped me many times and will have the spare parts you need.

    Buena Suerte.
