Inspired by Toms video (https://toms3d.org/2017/12/09/tmc2130-guide) about the quiet and sensorless-homing TMC2130 drivers, I started to build this printer a month ago. It isn’t finished yet (cable managament, …) but yesterday I did my first prints and they went very well, even without any printer settings tuning.

I wired them exactly like Tom did, expect the two cable select pins X_CS_PIN and Y_CS_PIN, because I also have a RepRapDiscount Smart Controller connected:
X_CS_PIN from 53 to 66
Y_CS_PIN from 49 to 44
This has to be changed in pins_RAMPS.h (if using Ramps 1.4)

The Z-Sensor is a http://www.escher3d.com/pages/order/products/product1.php which works very exact and has a low building height so I could mount it under the extruder motor near the nozzle. Therfor i added a mounting point to the extruder_strap.

For X-homing I printed a 21mm long cylinder with a 8.5mm hole as the stopper.

The first thing I printed was the yellow fan holder seen in the picture, the second one the 3DBenchy
