After several testing is look like my driver are ok and my motor too but I always have this error after the empty driver space in 2.2 or 2.1 . I have all motor work with buzzer test except the one is after 2.1 motor connction dont mather if is z, z1 or z2. So first things I think about, do I need to put a driver in driver connection for the one I don't use ? Board is octopus 1.1 in a trident setup.

No, you do not need to occupy the unused port. This must be a configuration error.
