I’ve got a working Klipper branch with a SET_EXTRUDER_NOZZLE_DIAMETER and SET_EXTRUDER_FILAMENT_DIAMETER that allow “live” changes of the nozzle and filament diameters! pedrolamas/klipper at pedrolamas/nozzle-filament-diameters (github.com) Right now, the only use-case I can think for something li…

Nice idea! [image] pedrolamas: changed mid-print to a different nozzle size But keep in mind that you have to change the sliced file too… :wink:

[image] EddyMI3D: keep in mind that you have to change the sliced file too True, but I would assume that anyone using this would have thought of that, and so sliced part of the model with nozzle A, then send an M600 or PAUSE command to change be able to change nozzle, and then slice the rest …

Thanks for doing this! I’d like to get this change-nozzle functionality into klipper. FWIW I have a plugin that does this which you can install right now: GitHub - garethky/change-nozzle-klipper-extra: klipper extra that swaps nozzles without a reboot It has the added benefit that the nozzle setti…

On second thought, if you get this shipped I’ll just override it and let my plugin live on.

Gawd Yes. I’m still pretty new to Klipper and putting it through it’s paces. I started using it on an Ender 2 Pro with a Sonic Pad, then the Sonic Pad on a newly build Voron 2.4 (350) and now Klipper on a LibreComputer. This is my first nozzle change (.4 to 1mm) in the 2 months I’ve been using Klipp…

What does Klipper do with the nozzle diameter? I’ve used nozzles from .2mm to 1mm and never changed that setting in the firmware.

Ah, right. I rely on extruders to do non-extrusion filament handling so I had to “bypass” this a while back by setting the “max_extrude” parameters to comically high values. EDIT: So I guess that would be another use case for this feature! It might be beneficial to be able to set a “dummy” nozzle v…

Do you mean for something like filament loading on a Bowden system? You can set max_extrude_only_velocity and friends to do that kind of thing.

Right. I have them all set to 1000 and that works fine for my purposes, but it also means I’m essentially disabling the entire function this thread is about.

Only calculating the safety limits for extrusion. See Move exceeds maximum extrusion (AA mm^2 vs BB mm^2) for the math behind it.
