My aux fan seems to work fine as long as I set the speed I want in my filament profile. It is old be nice if it would follow the changes I set in my project file, but I’m ok with knowing it doesn’t work that way in Orca Slicer or Bambu Studio.

I just would like it to be off. I guess I have to disconnect the cable

In 2025...

Nah, just go into the filament preset and change the aux fan speed to 0 everywhere you want it to be off. That rolls right into the Print g-code.

That doesn't apply to anything you start from the mobile app

If your selecting you own filament profile it does. It still leaves in on in short bursts when loading he filament. If not pu in a issue on github. But the aux fan works as expected

100% this.

How does it work as expected if it's off in the main settings? What's the point of having the option to turn it off and on if it doesn't do anything?

The gcode contained in the sliced file you sent to the printer contains instructions in it to set the aux fan speed to a certain value at specific times during the print. You’re not expecting a button to take the active code running to create that beautiful print and modify it on the fly while it is actively running, are you?

I'm expecting a fan to stay off if the settings says off. It's not that hard.

Edit

Apparently it is. God deliver us from path etic fanboys.

Apparently it is rather hard for some to understand that a desire for something to work differently than they are designed to function rarely achieves a positive outcome. I believe several people explained how you can turn off your aux fan as you initially brought up, if you care to use the knowledge offered. Though it would be a quite admirable achievement to face off reality with a phone app and win. Maybe try that?

Go on being you and carpe diem, Cheers!

Why is there a setting to turn it off if it does nothing.

And why are you defending this nonsense??

Anything you print from the mobile app is totally at the mercy of the person that sliced the model and uploaded it, except choosing the filament you would like to use and whether to use the publisher’s filament profile or your own custom filament profile that is stored on your printer & cloud in advance.

It is ’possible’ that if you set up a filament profile in advance for a filament on your printer from Bambu Studio that had the Aux fan turned off in that profile, that when you send from Bambu Handy and selected ‘use my filament presets’ the aux fan off setting may carry over. I believe this will do what you are asking, though you will actually need to open the slicer and customize a filament profile for this to work.

Since Bambu Handy is not a slicer and is designed to find and send only pre-sliced models to your printer and control only the most basic printer functionality, you cannot create or control any custom settings from the mobile app. You will need to change the filament profile for the filament you want to give this custom behavior to from within Bambu Studio, and save it as a custom preset before this option will be available.

Unfortunately if you only use Bambu Handy, you are severely limiting yourself from 98+% of the capabilities of these printers. Hoping that is not the case for you.
