    Hi all. I have Takisawa Mill CNC with fanuc OM. When I finish I always set XYZ to zero. But last day, when I run this machine and I can not control Z By handle, by Jog dial, X and Y run in good. system run without any alarm. I think Z have problem check with stop switch or proximity but all in good condition.
    I try many way to check but nothing happend. Please give me some ideas to sort it out. many thank

    I assume there are no alarms on the screen or on the drive. If you have not checked the drive please do so and post the info. My guess would be that there is something locking you out intentionally. Such as the Toolchanger which may not have the arm at home or some status related to it. The machine does not want to move and crash into the ARM or something. Also check to see that the spindle is clamped. This sometimes prevents any axes from moving.
