DRV8825 marlin 2.0 settings - configuration.adv.h
March 28, 2020 12:35PM
Hi, I have an SKR E3 DIP V1.0 and I am trying to install some DRV8825 stepper drivers. I have the jumper pins set all to the right side (jumping red and black pins) and all 4 in place. I tried to follow the instruction manual for the right placement so I hope I got that right.

From what I understand, these drivers have the ability to do 32 microsteps instead of 16.

I have changed the steps per mm in the configuration.h file to double what they were for the A4982 steppers.

Do I have to change anything in the configuration.adv.h file? I noticed this section and I'm not quite sure what it should look like for my drivers:

/**
* Custom Microstepping
* Override as-needed for your setup. Up to 3 MS pins are supported.
*/
//#define MICROSTEP1 LOW,LOW,LOW
//#define MICROSTEP2 HIGH,LOW,LOW
//#define MICROSTEP4 LOW,HIGH,LOW
//#define MICROSTEP8 HIGH,HIGH,LOW
//#define MICROSTEP16 LOW,LOW,HIGH
//#define MICROSTEP32 HIGH,LOW,HIGH

// Microstep setting (Only functional when stepper driver microstep pins are connected to MCU.
#define MICROSTEP_MODES { 16, 16, 16, 16, 16, 16 } // [1,2,4,8,16]

Is there anything else besides this I have to change or look at?

Thank you
