Hello and how are you all members who read this

This is my first Thread.

So...

Today i try to setup "bar puller" on my Index GU 600, but there is error

After all setup for example:

.
.
.
M5
G0 X250 Z320
G94 F0.2
G0 Z-90
G1 X30
M69
G1 Z80
M68
G1 X50
M30

This is example, problem is when chuck (jaws) is opened with M69 there is error *3* which means that is error (chuck (jaws) is opened and program cannot continue.

Any solution?

Thanks (:

P.S. Sorry for my bad english
