Stepper driver SD6128

I’m using tmc 2130 with SPI interface in my kossel build the motors have 2.0A peak. I’m using 12v in my power supply. That driver are winey at 12v its goes very hot. I read that is good for a low-current motors.

With that said I'm looking for a good driver, (good resolution, silent). I've found SD6128 that uses the chip THB6128. However I'm not seeing the configuration for that drive/chip in marlin 1.1.9. So I'm investigate how to connect this driver using marlin.

Could anyone give some help were? There is any other good drive for my spefications?

You treat any driver that comes without SPI, like a standard Pololu driver:
You set the Vref via potmeter and calculate steps/mm according to the jumper settings inside the driver socket.
Then change this line in Marlins configuration.h:

// X Y Z E steps/mm
#define DEFAULT_AXIS_STEPS_PER_UNIT   {200, 200, 200, 140.6}  //  steps per mm for Kossel (GT2, 16 tooth @1/32 and e-steps @1/16)

Thanks for for your reply. So any drivers that not have any SPI interface we should choose the A4988 standard driver in marlin.

But for example the LV8729 DRIVER not have any interface (SPI or UART configs) and we've a option to choose in marlin 1.1.9. In that case we choose this driver code and set the steps configuration acording to microstep seletor in the board (ms1, ms2, ms3)??

Thanks
