Bridges over 15% grid infill?

I have a part I’m trying to print but bambu studio doesn’t seem to count the layer right over the grid infill as a ‘bridge’ even though it should. It is trying to lay down a normal full speed layer and thus it’s not adhering properly so the print is perfect up until this point then it is a mess. you can see in the first pic the grid infill, then in the second pic is exactly 1 layer on top of that.


Here’s a Pic of the part

Have you tried other solid infill patterns?
And only use concentric for the top layer?

I see the warning about PLA and PETG in the mixture. Are you trying to use different material for infill? PLA and PETG do not bond well.

yeah I’ve tried a few but the software doesn’t seem to want to treat it as a bridge. I finally forced it w/ a modifier but it’s a bit frustrating

no not for infill… I’m using PLA for support. It offers 100% support so it looks super nice and breaks clean.

Can you share the 3mf file here?
I guess there is some weird setting causing this.
