    NEED HELP! Spindle wont turn on

    Hi,

    I have a china cnc with a 4 Axis RZNC 32 LED DSP controller.
    The machine works years without errors.
    But from today i cant turn on the spindel.

    Need advice where to look for the error.

    Thanks.

    Check all the connections for tighness.

    Is the relay pulling in? If not, is the relay getting a voltage to energise?
