I’m running the test in the opening of easel. X and Z work fine.  
Y jumps in opposite directions. I removed y-2 wiring  
and the machine moved, but in the opposite direction of the Arrow.  
I reversed the Y1 & 2 wiring, and got same opposite jumping result!  
Please help. Thank you!  
-Tony

Each stepper have 4 wires =\> 2 pairs. Say A+/A- and B+/B-  
Swap one of the pair around, like =\> **A-/A+** and B+/B-  
Any pair will do.
