Need Help! Akira Seki Lathe Zero stting (cross posted from Fanuc Forum)

Hi Guys,

I need to know how to re-zero my axis after a turret bump. I have retrammed the turret to .0002 across the face and centered on a bar holder. I need to know how to reset the home switch offsets so X0 in the tool offset page is really X zero. Also where is the Z offset referenced from? The switch or the spindle nose? Akira Seki has been no help and there is not a local dealer in my area (phoenix)

Machine control is a Fanuc OT-C with std encoders (not absolute)

Thanks in advance

Chris
