More info

The TMC2208 provides an integrated motor driver solution for 3D-Printing, Cameras, Scanners and other automated equipment applications. The device has an integrated microstepping indexer, the completely noiseless current control mode StealthChop2™ and is intended to drive a bipolar stepper motor. The output driver block consists of low RDSon N-Channel power MOSFETs configured as full H-bridges to drive the motor windings. The TMC2208 is capable of driving up to 2A of current from each output (with proper heatsinking). TMC2208 is designed for a supply voltage of 5...36V. The device has a step and direction interface and can be configured with digital pins.

What does that mean for 3D Printers and Marlin?
Well Marlin now supports the TMC2208 which enables UART/Serial control to and from your drivers which communicates high current draw which enabled Marlin to know when steps are skipped, filament is stuck, or even homing your axes without the use of endstops.

This is a game changer for 3D Printing builds.
