The stepper motors are very hot. How can I reduce the current on the drivers? Firmware marlin.

makerbase-mks commented 4 years ago

You can change it of pins_MKS_ROBIN_MINI.h

define DEFAULT_PWM_MOTOR_CURRENT { 1030, 1030, 1030 }

You can decrease the value of DEFAULT_PWM_MOTOR_CURRENT, like this:

define DEFAULT_PWM_MOTOR_CURRENT { 800, 800, 800}

good luck for you!
