In this post I go over how to use the TMC2208 Stepper Motor Controller. We will learn the basics, how to use microstepping, how to set the current limit to avoid exceeding your motor current limit, how to connect to Arduino, and we will go over several examples which will show how quiet the TMC 2208 runs.
