Hi I have auto zero turned on in homing limits settings but yet when the machine goes to home position it does not zero the numbers out any ideas why ? Thanks Gary

You are likely viewing the wrong Coord system.
Homing is in Machine Coords.
You must select Machine Coordinates to see that it is zeroed.
If you are in Mach coords, you might have a Home Off value entered which would show in the DRO.
