In late 2021, klipper removed some features that were deprecated over the course of 2020 and 2021. This document summarizes them briefly and shows how to fix them:

Removal of step_distance

step_distance describes the distance covered by a certain axis with 1 stepper (micro-)step. The downside of this parameter (and one of the reasons for its removal, is that if one were to change the microstepping of a stepper, the step_distance changes as well. Klipper therefore removed the step_distance parameter in favor of rotation_distance and full_steps_per_rotation. These two parameters are unaffected by microstepping, and can be easily determined by inspecting the used hardware.

Perform the following steps to convert your config:

• comment out the old step_distance parameter
• add three new parameters:
