Setting up Part Cooling settings in Studio

Bambu Lab Software Bambu Studio

I’m finding Studio’s Part Cooling settings to be a bit difficult to follow. I’m assuming you set this up in the Filament Profile, in this dialog:

Filament Settings - Part Cooling
Filament Settings - Part Cooling1752×1160 269 KB

Is this correct? Are there any other profile areas that you can make part cooling decisions? The first item, Cooling for specific layer really doesn’t make sense. That’s not addressing cooling on specific layers, just whether cooling is active for the first n layers. I’m not seeing any other ways to address specific cooling setup for specific layers. Are there ways to set something like this up? I’d like to have no cooling on the first 2 layers, 10-15% on layers 3-5 and 20-30% on layers > 6. I’d like the cooling to slowly increase over the layer ranges. And 50% cooling on overhangs (bridges).

I can see how to set no cooling on the first 2 layers and 50% for overhangs but not sure how to setup the other needed parameters. How would I do this?

What does Slow printing down for better layer cooling do? Slow down to what? Does that mean slow down to the set Min print speed?

What is the Auxillary part cooling fan? I have an A1, I’m assuming I don’t have an Auxillary fan, correct?

Appreciate any guidance. Thanks.

Hi @sealyons

  • So, you already did the first two layers.
  • You need to add custom instructions for the remaining g-code. The command to change the part cooling fan:
M106 P2 S{speed}

With a speed in the range [0, 255]. E.g. 15% → M106 P2 S38
Since you want to do it layer by layer, adding a custom g-code to the specific layers is the best option. For that:

  1. In the preview tab, use the slider on the right to select the desired layer, and right-click on the plus circle:

  2. Select the “Add Custom G-code” option:

  1. Add the custom g-code, e.g. for 10% at layer 3:
