[SMOOTH_TIME=<pressure_advance_smooth_time>]`: Set pressure advance
parameters. If EXTRUDER is not specified, it defaults to the active

the active hotend.
#### SET_EXTRUDER_ROTATION_DISTANCE
`SET_EXTRUDER_ROTATION_DISTANCE EXTRUDER=<config_name>
[DISTANCE=<distance>]`: Set a new value for the provided extruder's
"rotation distance". If the rotation distance is a negative number
then the stepper motion will be inverted (relative to the stepper
direction specified in the config file). Changed settings are not
retained on Klipper reset. Use with caution as small changes can
result in excessive pressure between extruder and hot end. Do proper
calibration with filament before use. If 'DISTANCE' value is not
