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
