[SMOOTH_TIME=<pressure_advance_smooth_time>]`: Set pressure advance
parameters. If EXTRUDER is not specified, it defaults to the active
extruder.
-- `SET_EXTRUDER_STEP_DISTANCE [EXTRUDER=<config_name>] [DISTANCE=<distance>]`:
- Set a new value for the provided extruder's step_distance. Value is
+- `SET_EXTRUDER_STEP_DISTANCE [EXTRUDER=<config_name>]

+ `rotation_distance/(full_steps_per_rotation*microsteps)`. Value is
not retained on Klipper reset. Use with caution, small changes can
result in excessive pressure between extruder and hot end. Do proper
calibration steps with filament before use. If 'DISTANCE' value is
