Setting Up and Calibrating Sensorless XY Homing

When using the TMC2130 / TMC2209 / TMC2660 / TMC5160 drivers, the StallGuard feature makes it possible to set up sensorless homing on the X and Y axes for CoreXY machines. The Klipper project has a page with documentation and recommendations on getting it working.

Following are some more detailed instructions and suggestions to supplement the Klipper documentation specifically for Vorons.

Written for fairly adept technical users, preferably of Debian GNU/Linux, not for absolute beginners.

You'll probably be working with a single smartcard, so you'll want only one primary key (1. Sign & Certify) and two associated subkeys (2. Encrypt, 3. Authenticate).
