I need to add two external stepper drivers to my MKS Gen L board. I am using
E1 as an extra Y-axis and that is working great. I have three Z motors and I want to move them independently if I can.
I am using:
I step up the pins in Marlin and set it to use three motors but when try to move Z only the normal Z motor moves, i.e. the default on-board z stepper driver.
What else do I need to do?
