Hi all, We are trying running ID thread on main spindle using lower turret and face rigid tapping on sub-spindle using upper turret. Every time the program approach M29 code it stops ID thread and completes rigid tapping and then completes the remainder of ID thread. Is is possible to run simultaneously both chucks or M29 code prevent that from happening. An example of program:
UPPER :
N28( 1/2"-20 FORM TAP LH)
(TOOL SPINDLE)
(SUB SPINDLE)
