#### SET_NOZZLE_DIAMETER
`SET_NOZZLE_DIAMETER [EXTRUDER=<config_name>] DIAMETER=<diameter>`:
Set a new value for the nozzle diameter of the specified extruder
(as defined in an [extruder](Config_Reference.md#extruder) config section).
If EXTRUDER is not specified, it defaults to the active hotend.
Changed settings are not retained on Klipper reset.
