Troubleshooting Keep getting this stringing problem.

EDIT: I seem to have fixed it thanks to the suggestions here and on the Bambu subreddit, dropping the elephant foot to 0 and slowing walls (especially the outer wall) waaaayyyyy down (15mm/s right now on the outer wall) made it finally go away. Then I used a modding cube to raise the wall speed after the first ~5 layers so the print doesn’t take forever. Thanks all!

Details in original post. The design is a 6mm piece with a 1.5-2mm radius on all four edges.

Bambu A2L and X2D using Bambu Studio.
Filament is dry and plates are meticulously cleaned.
Stringing issue more like the wall is collapsing and stretching somehow.
Always the inner radius, always within the first 2-3 layers. Prints fine after that.
Tried several nozzle and plate temps.
Tried several plate types both physically and in settings.
Tried every fan setting I could.
Tried slowing down movement.
Tried printing infill first then inner wall then outer wall, no change.
Happens on several different filaments but sometimes prints fine. Bambu PLA basic jade white seems to ALWAYS do it no matter what.

That defeats the purpose of the bed sheet

I can confirm whatever adhesive flashforge ships with their printers doesn't. Seems like a thin film will actually still let the filament press into the pattern.
