When did it last work properly?
What has changed since then?
You've done half the diagnosis work, proving that tour Z motor works on an alternate driver, now you need to try your Z driver on another motor to definitively isolate the problem to just your Z driver.
You don't give any details of your hardware, if I had this fault on my system I would swap out a driver but this is not an option on "All in One" Break Out Board and driver units where one failed driver renders the whole board scrap.

I Changed the leads from the z to x then the x worked the z fine but the z driver would not work the x .I got the machine with this problem http://uploads.tapatalk-cdn.com/20160414/350faa521dadaaa1e4855b91a81666c0.jpghttp://uploads.tapatalk-cdn.com/20160414/02d7256547eaf556de97a66f8b049ba9.jpghttp://uploads.tapatalk-cdn.com/20160414/a57acecafdf0e0eca613c97a4e6bf9e9.jpg

Examine all the components and tracks on the faulty driver section of the board (both sides) and compare to the good ones, I'm betting there's a toasted component or track somewhere on there.
