    Maybe cleaning of control modules could help. Clean the rack connectors also.

    Check power supply stability or try other ±24V PSU. Try re-installation of Okuma software.

    Change the board. But if you can no do it change CNC to China. It will be more cheaper then buy board.

    I remove all OKUMA CNC with servo motors and drivers and install new China CNC TD1000 with 2 new servo motor and 2 new servo drive.
    I have no any problem now.

    hy aike this is the 2nd time i hear about someone replacing the cnc

    here is the other : https://www.cnczone.com/forums/okuma...ml#post2076724

    i think is a god idea ( especially if you can do it yourself ), to bring back to life an older model; thus if machine/mechanical is ok, then why not just rewire it ? kindly
