Sounds like a wiring issue, check all wires are secure.

Using the MDI  type G0 X1 Y1 Z1 Then swap the cables or pin out in configuration for the Y and Z and do the same command in the MDI.
What happens?

When you changed the pinout (same as physicaly swapping wires) the Z didn't move/ was still the problem?
