Nozzle size option?

It would be nice to have a separate nozzle size option besides filament option in order to enable easy changes in configuration for volumetric flow control for machines with multiple tools equipped with easy to swap nozzles like the Revo or Dragon.

There was the option but never really used by anything as far as I know.

https://docs.duet3d.com/User_manual/Reference/Gcodes#m404-filament-diameter

M404: Filament diameter
Parameters
Nnnn Filament diameter (in mm)
Dnnn Nozzle diameter (in mm) (deprecated in 3.4-b1)
Examples

M404 N1.75
M404 N3.0 D1.0 ; See note below about D parameter
Notes
Enter the nominal filament width (3mm, 1.75mm) or will display nominal filament width without parameters.

The 'D' parameter is used to properly detect the first layer height when files are parsed or a new print is being started. From RRF 3.4-b1 the D parameter is deprecated and no longer used in detecting the first layer height.

The values of this command are currently only used by the print monitor and only when the slicer reports the filament usage by volume instead of by length.

I guess that people won't use it if you don't have a relevant UI control to make it easy to use. But that's why this is in the DWC Wishlist. You need a control to make it easy to use.

@0nn0 My approach is to redefine/save the tool details depending on the selected nozzle diameter. I made a RRF macro plugin for E3D Revo nozzles a while back: https://plugins.duet3d.com/plugins/RevoConfigPlugin.html

I'm planning to make a printer with multiple tools (based on LGX extruders) and equip it with revo nozzles. So I would like to see a setting per tool, much like the filament drop down.
