Stepper voltage control MKS Robin Mini V2.x
Hi Folks,
Can anybody tell me does firmware stepper voltage control work for the Robin Mini with Marlin 2.x? I am in the process of converting over and want to know what to expect here.
I have observed that the new Marlin 2.0 firmware, the pins_MKS_ROBIN_MINI.h file, has an adjustment to the reference voltage of the stepper drive: // Motor current PWM pins #define MOTOR_CURRENT_PWM_XY_PIN PA6 #define MOTOR_CURRENT_PWM_Z_PIN PA7 #define MOTOR_CURRENT_PWM_E_PIN PB0 #define MOTOR_CURRENT_PWM_RANGE 1500 // (255 * (1000mA / 65535)) * 257 = 1000 is equal 1.6v Vref in turn equal 1Amp #define DEFAULT_PWM_MOTOR_CURRENT { 1030, 1030, 1030 } // 1.05Amp per driver, here is XY, Z and E. This values determined empirically.
