    NC-PC communication failed

    Hello,

    I’m receiving an 'NC-PC communication failed' error when starting the Hartford milling machine, which is equipped with a Mitsubishi Meldas 700 controller.
    Restarting the machine usually resolves the issue.
    Are there specific troubleshooting steps or known fixes for this issue?

    You might need to check the cable connection or the power supply.
