modified: klippy/kinematics/extruder.py Added the ability to set the nozzle diameter at runtime for an extruder. This is useful when using multiple toolheads with different nozzle sizes, or when volumetric extrusion is enabled. It’s also helpful for printing purge lines that exceed the maximum volumetric flow of the current nozzle: you can set a larger nozzle diameter for the purge line and then restore the smaller diameter for the print. Taken from Klipper3d/klipper#7123 .
