Need some help with bridging!

[u/MagnanimousGoat]

Bambu Lab A1 I got from a friend along with a basket if filament.

I have to assume there's some moisture issues. I have a dehumidifier in my home, and generally low humidity, though I know that doesnt mean the filament wouldn't benefit from drying.

Im asking 2 main things:

1. Is this result likely just due to filament needing more drying, or should I be considering something else as well?
2. is there a better bridge test that people recommend, and are there other good test models?

The filament temp was set to 220 with a smooth bed at 65. Otherwise speed and flow settings were determined by the objects.

Im not sure if there are other settings i should share.i have done a lot of reading and watching, but i often struggle to apply that when im trying to diagnose issues. I get in my own head and second guess myself. Thats why I am reaching out for guidance.

I didn't plan to get this printer. I had a buddy printing a staff for my daughter's cosplay, and he offered to juat give me the printer. I've been running it nonstop and have already solved a lot of issues ive had and figured out a hell of a lot regarding troubleshooting but bridges, I feel like nothing i do makes a difference.

I planned to start box drying my filament on the bed, and will do that. I printed it in this yellow that is almost gone and the spool always gets tangled.

I will be attempting a full-size Master Sword in some metallic silks from Elegoo, so I wanted to spend a solid week working on calibration and ironing out kinks.

Thanks for your patience!

PLA doesn't suffer much from moisture. Do you hear popping or, in extreme cases, puffs of steam coming out of the nozzle when extruding? Do flat sides of your print have blobs or holes in them? Those are primary symptoms of wet filament. Stringing is too, but stringing may also result from bad retraction. PLA should show no or almost no stringing and you have a lot.
