    Question B-axis won't come to main spindle in program mode. Puma TT2500 SY vs Fanuc 18i

    Dear friends.
    Asking for help.
    Please tell me who has encountered Doosan (Daewoo) Puma TT2500sy. Fanuc 18i.
    I was wrote a two little programs for upper and lower turrets.
    Its all right.
    But after finish of producing a part, I need to pull the stockbar with second spindle.
    If Z2 in reference point I can move the B-axis, but in this case I can't to reach the bar by seconde spindle. So I need to moove Z2 axis closely to main spindle, moreover, the cutting cutter present on the lower turret.
    So. I use, as in manual
    Upper turret in the reference point.
    B-axis in the reference point too.
    Lower turret - not in the reference point
    .....
    M169 (OPEN CHUCK 2 SPINDLE);
    M86(TORQUE SKIP)(it will need later);
    M131(ALLOW MOVE OPENED SECOND CHUCK - ON);
    M502(Z2 REPOSITION TO PREPARE FOR CUT - DONE); (in the another file)
    M170(INTERFERENCE TO UPPER TURRET CHECK - OFF);
    G0 B10. (MOVE SECONDE SPINDLE TO DEFINED POINT); - And here STOP.
    (In fact B-axis try to move. Travel +- 1,5mm and stop)
    The small red lamp onthe panel is ON. But the Alarm or Messages screens are empty. So I even cant to understand what it want from me.

    Please help.

    is the interference zone's parameters properly set?
    Can you jog the B to the location desired while using the handwheel?
