I have this one squiggly layer of support interface material showing up under some PLA support in my print, but don’t understand why. My intent is to have the support interface be on the flat undersides and use the standard “pla on pla” supports for the flat horizontal surfaces.
Hi @Titanium,
Welcome to the forum.
The slicer is working as expected.
That support material layer relates to the base settings, which only entail spacing and pattern. It’s different from the bottom settings, for which you opt not to use the support filament. I am unaware of any workaround for changing the material at that layer.

Thanks for the help.
So there is no way to get rid of this “base” layer? It is not accomplishing anything that i can see.
I was hoping to get rid of the unnecessary swap from PLA to Support back to PLA. Plus it leaves a squiggly pattern on the flat horizontal surface.
There is a setting (“avoid interface filament for base”) that should do that: Bambu Studio 1.8.2 Release Notes | Bambu Lab Wiki.
I did a swift test and couldn’t replicate the results shown in the post, and also it is intended for other purposes.
I can try to explore further later and come back to you if I find something new.
You can change the type of pattern and distance (density). That base pattern is also present if you don’t use a support material; in my experience, it seems to work well.

I enabled “Develop Mode” in Preferences, but I don’t see the “Avoid interface filament for base” option appear under “Filaments for Support” in the Supports tab.
The squiggly pattern I could live with, but it is the wasted time and wasted support filament due to the unneeded swaps between the PLA and the Support material that is my main concern. I guess worst case is I could cut the model into 8 pieces and then use different support settings on the cut pieces.
Would it be useful if I uploaded the model or a full picture of the model?
Thanks again for your help.
