    Cracks in the membrane surface? Coolant in behind the membrane can turn into adhesive and stop button function.

    You can home the machine without resetting the machine. Just power up restart as normal, alarms will be canceled when done.

    So normally you'll startup the machine and have a "102 SERVOS OFF" message. Reset clears the message and the servos come on.

    Do you get the audible beep when you hit the reset button?

    What about using the power up/restart button? That should also clear the 102 alarm as the previous poster mentioned.

    gotcha I didn't see that part ! then its either a bad diode in the matrix. or the keypad is shorted or broken. a very common issue of a machine of that vintage.

    That was why I asked about the beep.

    My 1993 occasionally goes on strike with what I call the "running alarm". It will finish a tool, Z up, than nothing. Everything halts with the spindle still turning, and the control is totally dead. Even the E-stop does nothing. The only recovery is a power cycle of the control, then everything is fine again.

    @OP- when this happens, does the E-stop work?

    You might check the 770 cable to the I/O board (E-Stop). E-Stop button is normally closed.
    102 can also be from motor faults, tool change problem or power fail. Try disconnecting the servos and restarting.
    Rarely used, check the switch states on the diagnostic page. You might have one sticking. I have to re-home the X axis after the home all axis to get the correct value.
    Are your door switches still active?
