Did you assembled the Z axis straight and the same height? and the rods, do they bending or not?
perhaps you can check this link here for point 2:

Rods are straight used level and measuring caliper nothing bends evrything is plugged in properly I don't understand what's wrong

[Mark]

so how's the voltage of your motor driver? could it a little low?
and maybe you can post some pictures here to check it.
