I will try to explain the best I can but this is really weird.
I can only move 1 axis at a time no matter how I connect both stepper drivers.
See pictures
-----------------------------------------------------------------------------------------------------------
Normal connection
Z+ and Z minus are working as they should
No move on the X axis
-------------------------------------------------------------------------------------------------------------
If I switch signal cable ( X signal on Z stepper driver and Z signal on X stepper driver)
No move on the Z axis
X axis become Z axis
--------------------------------------------------------------------------------------------------------------
If I switch power cable going to stepper motor (signal cable in normal position x signal to X stepper driver --Z signal to Z axis driver)
Z axis become X axis
No move on the X axis
------------------------------------------------------------------------------------------------------------------
If I switch both, signal cable and power cable (from X to Z and Z to X)
X axis move
No move on the Z axis
