    Question Using Sub-spindle as tailstock tool change problem

    Hello,

    I'm trying to learn how to use sub-spindle as tailstock on my Hyundai Wia L2600SY lathe with fanuc 0i control.
    Now i have a live center on the sub side chuck and used for the B-axis movement:

    G0 G54 B-480.
    G1 G98 B-497.8 F200.

    The problem is that the machine won't allow to change tool if the B-axis is not fully retracted to reference point so i have to move b-axis back to home position in every tool change.
    Even in manual jog use the machine alarms if i try to rotate turret when the b-axis is even 0.1mm from the home position.
    I'm using G30 reference point for tool change which i have set closer to main spindle.

    Is there a parameter to allow rotate turret when b-axis is not in reference point?

    SOLVED

    Change from PMC D0009
    D9#6 from 0 to 1

    This allows to change tools when B-axis is not at reference point.
