How to avoid stringing with normal condition?

Bambu Lab H2 Series
1

I printed this with default condition and it always cause stringing.

So I had to turn off AI Spagetti detection to keep printing even though stringing occured.

I tried to print that out with 50% speed however Spagetti still occurs.

What am i supposed to do?

2 colors being used are Black(External spool to left extruder) and Red(AMS PRO2 to right extruder).

Everytime I have to re-print the model again that I put negative part not to print the part of the model that are printed successfully.

I would make sure that you have the standard profile selected and not accidentally hit the balanced profile. On one of my parts I accidentally hit balanced and it slowed the speed down a lot which caused stringing for me.

This is all assuming that your filament has been properly dried. Even if it’s new, it definitely does not mean it’s dry

Thanks soooooo much.
I usually don’t change any profile.

I found that it usually fails to print because of spagetti when printing small detailed object like kitcard.

How can I dry filaments with AMS PRO2 or something else???

Filament drier, I happen to like the eBOX Lite.

When filament is manufactured, I understand that it is extruded through a water bath to cool it. Presumably the moisture doesn’t always get fully removed from every spool of every batch by every manufacturer.
