I'm getting a SPINDLE I/O FAILURE on my control display any saber 408 guys ever had this come up
From Gerber Support
Have them open the spindle controller cabinet, The display on the VFD should read call or call waiting.
Have them send a job over, does the display change? I need the message.
If not, have them check the cable that runs between the spindle controller and the E-box, if that is seated correctly with no defects then most likely the DUart card went.
