Marlin 2.0 MKS SBase 1.3; set driver current #94

Hi,

I would like to know how and where the current settings for the DRV8825 drivers are defined. I cannot find a default setting anywhere, I can find this on the configuration_adv.h. page but I cannot figure it out (I just don't understand it):

I changed line 581, the number of channels, to 5. I changed line 584 to have 5 variables, and set the first two (my guess is X and Y motors) to 1.5A Should I enable line 565? Or should I enable line 580? Or both? I tried to include the library mentioned at line 580 using PlatformIO in Atom, I don't know if I succeeded. Any help is welcome.

Cheers,

Hugo

This is how I have mine setup and seems to run good. My current settings may be different than yours but this is what works good for me on my ender 3. did you also uncomment #define DIGIPOT_I2C? I'm also assuming that you added the drv8825 drivers in the configuration.h.

define DIGIPOT_I2C

if ENABLED(DIGIPOT_I2C) && !defined(DIGIPOT_I2C_ADDRESS_A)

/**

//#define DIGIPOT_MCP4018 // Requires library from https://github.com/stawel/SlowSoftI2CMaster

define DIGIPOT_I2C_NUM_CHANNELS 5 // 5DPRINT: 4 AZTEEG_X3_PRO: 8 MKS SBASE: 5

// Actual motor currents in Amps. The number of entries must match DIGIPOT_I2C_NUM_CHANNELS. // These correspond to the physical drivers, so be mindful if the order is changed.

define DIGIPOT_I2C_MOTOR_CURRENTS { .9, .9, .9, .9, .9, } // AZTEEG_X3_PRO

For me a slightly different settings in the configuration_adv.h worked out 100% I have a delta printer D=300 H=450 MARLIN 2.0 bugfix from November 20, 2020 Board MKS Sbase v1.3 Home made ultralight duo floating extruder, 2 nozzles

//#define DIGIPOT_MCP4018 // Requires https://github.com/stawel/SlowSoftI2CMaster

define DIGIPOT_MCP4451

if EITHER(DIGIPOT_MCP4018, DIGIPOT_MCP4451)

define DIGIPOT_I2C_NUM_CHANNELS 5 // 5DPRINT:4 AZTEEG_X3_PRO:8 MKS_SBASE:5 MIGHTYBOARD_REVE:5

// Actual motor currents in Amps. The number of entries must match DIGIPOT_I2C_NUM_CHANNELS. // These correspond to the physical drivers, so be mindful if the order is changed.

define DIGIPOT_I2C_MOTOR_CURRENTS { 1.000, 1.000, 1.000, 0.400, 0.400 } // MKS_SBASE

//#define DIGIPOT_USE_RAW_VALUES // Use DIGIPOT_MOTOR_CURRENT raw wiper values (instead of A4988 motor currents)
