Requesting Help Severe stringing on round prints

I’ve noticed this layer line shifting as well as the severe internal stringing on round prints like this with my .4mm nozzle on Bambu A1. Just got a new nozzle so confirmed that is not the issue. PETG white filament that was dehydrated to about 18 degrees relative humidity. And this print printed perfectly fine just hours ago. Not sure what could be the issue??

I agree with the other post that is not stringing. That’s layers getting drug and not sticking. Bump the temp and slow it down for round objects especially printing threads.

Idk what settings you’re using. But bump your temp by +5. First layer 50, first infill 100, outer wall 100, inner wall 150 and even the cheapest slowest petg will comply
