On the inside of the machine, near the bottom of the Z axis way cover to the right of the X axis slide is a welded on bracket that looks kind of like half of an oval. This bracket moves when the Z axis moves. You have to use a Mazatrol manual unit to move the turret to the correct Z position, then command tailstock forward to move your body, then your quill. When the tail body moves forward and the roller switch on the back side of the tail body hooks up with the bracket on the way cover, the tail body stops and the quill moves forward until it contacts the part. At that point, slide the cam inside of the tail body to trip the roller switch inside of the tail body.The green light on the control panel next to your tail spindle switch must be a solid green in order to run your program.. A blinking green light indicates the switch inside the tail body has not been satisfied. You will need to command an M5 for spindle stop for the tail body to move either forward or backward. A simple M32 retracts it all. The Mazatrol unit requires only 3 lines.
One line with an X command (wherever works) and a Z position. The Z position is important.
One line with an M5 command.
One line with an M31
