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
