Two Z axis stepper motors

Hello,

I have marlin 2.1.2.1 and Iam building my own 3d printer. I want to controll dual Z axis stepper motors with two drivers. Iam using arduino with ramps 1.6. The second Z2 driver is pluged into E1 on the board. According to what I found I should change in the configuration_adv.h NUM_Z_STEPPER_DRIVERS, but I havent found anything like this in configuration_adv.h. Also I was trying to find something that could possibly be the right configuration change, but I havent found anything. Thank you in advance

Your looking at old out of date information.

Dual axis is now enabled by enabling the appropriate stepper drivers, you don't manfully set NUM_Z_STEPPER_DRIVERS

Eg #define Z2_DRIVER_TYPE A4988

And that is it

Now if you want dual z endstops also you need to configure #define Z_MULTI_ENDSTOPS In Configuration_adv.h

Note you will get this warning "Note: Auto-assigned Z2 STEP/DIR/ENABLE_PINs to unused En_STEP/DIR/ENABLE_PINs. (Define NO_AUTO_ASSIGN_WARNING to suppress this warning.)"
You can either ignore it, or add #define NO_AUTO_ASSIGN_WARNING to suppress the warning
