i am searching for stepper motor driver schematic using drv8825 controller which is from TI. I am using stepper driver but suffering from noise and need micro-stepping also.
Noise and missed steps on a stepper motor is usually from not having a high enough voltage to the motor. The voltage given on the motor data is not the voltage that should be used to drive it. Example a '5V' stepper would use much more than 5V in an application.
