Ah! That would be it. I didn't realize there was a "fan speed" setting under gcode preview.

I don't own the IP, so I can't share the project, but I can now see the results of any changes to the gcode for fan speed without having to manually dig through the gcode itself. You are a lifesaver. Thank you!

It should be yes. We could play 20 questions but if you save your project file from Prusa Slicer (File>Save project as) and then ZIP it up and attach it here we can then look at ALL the settings as a project contains the models and more importantly a copy of the 3 profiles you currently are using. You must zip it or the forum wont attch the file.

For example do you have Dynamic Fan speeds active ? Those are a Red/Expert level setting so you wont even see those if you aren't in expert mode.

Also what does the gcode preview show for the fan speed when you change the dropdown to Fan Speed ? Again another question that wouldnt be needed with a project :)

Is it possible to entirely disable the part cooling fan for a print? I am having trouble dialing in Varioshore TPU for maximum foaming, and I suspect it might be because no matter what I do the fan is turning on during the print. This cools down the filament as the bubbles are forming, resulting in smaller bubbles and a denser part. The part is a thin membrane printed flat on the bed, so there is no need for any part cooling.

In Prusaslicer under the "Filaments" tab I have selected the following:

Keep fan always on: Unchecked

Enable auto cooling: Unchecked

Bridges fan speed: 0%
