| - | The TMC2208 is a German development. I was made in Germany, too LOL. This tutorial is about making the A5 quieter. It is not my intention to explain all possible options of the TMC2208. Like me, most users will buy these stepper drivers just for one reason: to have silence. I focus on installing and configuring these drivers.\\ | + | The TMC2208 is a German development.

| The most noise comes from the Y-axis and the X-axis. Because the Z-axis rarely moves when printing you do not hear much noise. The TMC2208 can deliver less power than the standard A4988 driver. One Z-axis driver needs to power two motors at the same time. The avaliable motor current is divided between both motors. \\ | The most noise comes from the Y-axis and the X-axis.
