My Gantry Mill with Fanuc 18m Controls was working fine yesterday morning. Now it is as if the ( + ) key is enabled and will not disengage. I've hard reset the machine numerous times, and checked to see if the key was stuck. As soon as I press the Jog or Home button, then select an axis the machine begins moving in the ( + ) direction. Is there a way to soft reset the CPU ? Any help would be appreciated. Thanks.
