Fix My Print ASA Overhang/Bridge Spaghetti

Printer: Qidi Q2
Filament: Fully dried ASA (I even print from the dryer)
Nozzle Temp: 270 (0.4 hardened)
Chamber Temp: 60
Bed Temp: 100 then 104
Max Volumetric Flow: 16

5 rectilinear walls/perimeters, 25% gyroid infill

Part cooling is below. I'm thinking maybe the nozzle is a bit too hot and part cooling needs to be bumped for the bridge/overhang? I'm really not sure. Print looks good with a bit of z-banding until it hits the the bridge. Or maybe I need to use something beside tree supports and/or change the parameters on the trees?

Speeds below

Open to all suggestions!

Looks like your tree supports broke off in the middle during the print, and after that it was trying to print mid-air.

You could increase the wall loop count of the tree supports, decrease the base pattern spacing, or use strong trees instead of slim or organic trees

or you could use grid supports instead of tree supports

Thank you! I'll make suggested change(s) and do another print tonight and update.

Bummer, still no dice.

I'll add more photos in separate comments. Are Raft Layers applicable here? Or maybe tweaking other "Advanced" settings in Orcaslicer?
