## What it is
A Klipper python extra that automatically calculates and tunes TMC stepper motor driver register values based on motor datasheet information and a user-selected tuning goal. It enables modes like StealthChop and CoolStep, optimizes for low power and quiet operation, and supports sensorless homing on supported drivers.

## Use cases
- automatically tune TMC stepper drivers in Klipper
- reduce stepper motor noise and power consumption on a 3D printer
- enable StealthChop and CoolStep without manual register configuration
- set up sensorless homing with autotuned TMC2209, TMC2240, or TMC5160 drivers
- optimize driver registers from motor datasheet values
- keep 3D printer motors running cooler with automatic driver tuning

## When to choose
- you run Klipper firmware with TMC2209, TMC2240, or TMC5160 stepper drivers and want automatic tuning
- you want quieter, more efficient stepper operation without manually calculating register values
- you want sensorless homing combined with autotuned driver settings
- you use KIAUH or Moonraker and want a community extension with automatic updates

## When to avoid
- you use TMC2130, TMC2208, or TMC2660 drivers, which are untested
- you need full manual control over every TMC register value
- your printer cannot provide adequate cooling for hotter-running drivers
- you don't use Klipper firmware
