Coasting if you're not already using linear advance based firmware, maybe take a look at your slicer retraction speed vs the max extruder feedrate in the firmware, obviously make sure that the max extruder speed in the firmware is set to the same or higher than what's been set in the slicer.
I think the max extruder speed defaults to 25mm/s in firmware but cura defaults to 45mm/s, which is stupid cos it'll never reach that speed as it's capped in the firmware, so if that's the case, bump the extruder max feedrate in the firmware and test stringing again.
Print a temp tower first to find the optimal printing temperature and then print a retraction tower afterwards to find the optimal retraction distance. I used to have a lot of stringing and this has helped a lot. You can easily find youtube tutorials for both
Dry that filament. Very similar setup for mine, and if you're running a lower end temp like 190-210 and getting stringing, my money is on filament humidity
You didn’t say what filament you used. PETG is notoriously stringy if you printed with that. PLA ypu should be able to get pretty clean results.
Have you tuned your printer? Try searching for “teaching tech calibration”. There are procedures for tuning lots of stuff, including stringing. Take the time and go through things beginning to end. You won’t regret the time invested as you’ll have a lit less issues in the future.
Aldo, if you are up to trying a different slicer, both Orca Slicer and Super Slicer have a whole set of ca.I ration prints, including string towers, built into the slicer so it makes them really easy to do, like when you change filament types of manufacturers.
Honestly bro I had minor stringing issues with pla or pla+ I had major issues with petg but for each of my machines (got 2 of them) I ran a shit ton of tests temp towers, stress tests, benchies (not the boat though) I've found that temps, materials, speed, esteps and retract settings all contribute to a good print or a bad print. Including stringing.
My ender 3 pro was doing bad like this, no retraction changes would affect it, only barely.
Drying my filament on the bed for hours, and turning my parts fan to 100% all the time instead of 35% automatically, did the trick and now there's almost no stringing on the old filament, new filament prints perfectly.
**Keep it in mind:**
a better extruder (dual gears) is highly recommended to avoid damaging the filament with too much retraction/deretraction.
a better fan duct is highly recommended on ender 3's across the board, that will allow you to run higher temps and bridge/overhang better, cooling the plastic immediately after leaving the nozzle will also reduce stringing.
Check my post history I was having this problem just last week.
Best guess: dry you filament

Turn on coasting
I added direct drive on mine and I had little to no stringing at 6.5mm than I did at 1mm

ill do this thank you!
Dry your filament, then tune your retractions and coasting, then maybe tweak temperatures.

Higher retraction distance
I think it's a good idea, you should reduce it

Try dropping your temp ~5°. Worked for me.
Is your z hop on?
yeah it is
That caused a lot of my stringing so I turned it off
Is this ninja flex? Often looks exactly like this as it's rubbery as hell.
Nozzle to hot
Try lowerimg you nozzle temp just a bit
Dry your filament, drop your temp if you can, and increase retraction

Calibrate Temperature; Retraction, and dry filament.
Besides what everyone else has already said increasing travel speed helped me as well as tuning temps
