Could you tell me what has become of # define Z_DUAL_STEPPER_DRIVERS in Marlin
This option is no available in configuration_adv.h sad smiley .

I have a SKR 1.4 motherboard that I would like to use with 5 TMC2209 (X, Y, Z1, Z2).
Z1 on pcb pin Z.
Z2 on pcb pin E1.

I can't find any information, but on the first versions of MARLIN 2.0.x.x the option was still present ...

Thank you for your help, have a nice day smiling smiley.

It was renamed, as you can now have up to 4 Z steppers

// For Z set the number of stepper drivers
#define NUM_Z_STEPPER_DRIVERS 1   // (1-4) Z options change based on how many

Z2 will automatically be on the next free E axis. ie if you have #define EXTRUDERS 1 it will use E1
But say your tring to make a CNC with #define EXTRUDERS 0, Z2 will be on E0

Thank you very much for your answer, it's OK for me now smiling bouncing smiley.

Looking in Marlin I see a line that I had not seen "This section will allow you to use extra E drivers to drive a second motor for X, Y, or Z axes.".

It is a 3d printer winking smiley.
