Did you search the forum for ZRI?

You will need an input for each ZRI input.
What kind of machine do you have, what kind of home switches do you have?
How do you have the home switches configured now?

Are there multiple instances of ZRiHoming all to put on each input? Is there a way to change to homing macro so that once the index is hit it can back off a known increment before the next axis is homed
My machine has switches on X and Y and a Proximity sensor on Z - wired in series
