How To Correctly Set The Motor Current Limit On An A4988 Stepper Motor Driver

In this Tutorial video, I'm going to be showing you how to correctly set the motor current limit on an A4988 stepper motor driver. These drivers have become popular for CNC, 3D printing, robotics and Arduino projects because they're relatively cheap and really easy to use, they only require two pins to provide full control of a stepper motor.

There are two methods to do this, the one is to use a multimeter to physically measure the current flowing through one of the coils and the second method, which is the one we’re going to look at, is to calculate adjust the reference voltage on the driver, which doesn’t require the motor to be hooked up or powered.
