Hi,

Not 100% sure if this video can solve your problem but i had similar issues and this helped. I would think you have retraction turned off and you need it on, or maybe you're to hot.

I am to new to post links but go to youtube and search "3d printing stringing"

Yep, was the retraction, tweaked it from 1mm to 3mm, now my prints turn out merely fuzzy.

it's called 'stringing'.
different filaments will give you more or less and retraction and printing temp are usually how you manage it.
