I have been banging my head against the wall and have been tracking stringing issues for forever with my artisan. Has anyone solved this? I am back at stock settings and this is what I have for a three stringing tower test. Is it possible I set up the steppers wrong out of the box?
Stringing can have a number of causes - the steppers would come actually last in my mind 
Can you write what you already tried to change? Relevant settings/factors would be retraction settings, temperature settings and filament drying.
Hey thanks, yeah I have tried a lot of stuff. Retraction distance 1-3, speed 30-60, print temp down to 200. Also too low or retract too high I get head pull up errors. I changed print speed and travel speed to something higher than default but honestly both had very negative effects on print quality/completion.
There is filament which ooze more like petg and so there is more stringing. Also wrong humidity can influence the print.
Yeah I mean it’s pro pla matte finish. Maybe it’s moisture then?
I print pla with 190 - 200°C and retract about 1mm at 35mm/s with my dual extruder.
Hope this helps.

Perhaps a temperature tower might be a step forward, to find the optimum parameters for this filament. And yes, moisture may be an issue: I never really believed that with PLA, but since I started drying my PLA, I indeed have less stringing.
Yeah, it depends on where you live. Here in Germany I dry all my filament, and the change is significant for some filaments. But when you living in Texas, it is less required
Interesting, I’ve seen some improvement busting the hot end down to 190, and also I upped the retraction to 2mm and the speed to 60. I’m NOT getting head pulled up errors or clogged errors yet which is good. If I’m having trouble after this next run I might just go to a higher retraction and maybe 185
Also I’m using luban, I just noticed that the target temp walks up from 190 to 200 at the end for a stringing tower test.
hot damn starting to get better results, I think it’s a retraction issue, I’ve upped the retract distance to 7 and speed to 90 (prime is delinked and set to 60)
So high retraction causes clogging, less retraction is saver to print.

yeah foudn that out, busted down to 4 again and have less stringing. Going to do a benchy now
Ok I got it, wet filament was a large contributor. I turned off lift head and zhop and got a pristine benchy. When I busted it back to stock though I got some stringing even with a 2mm retract distance and 100 mm/s speed. When I have zhop on I get oozing and also collisions when doing complex parts. Is there a setting to avoid printed parts/collisions so I don’t have to use zhop?
Collisions? Wow… That’s a new one to me Its strange, since Z-Hop shut lift your nozzle up, out of the way… I use Prusa Slicer or Cura, never had collisions. If you have, perhaps send the model and slicing settings to Snapmaker, they need to fix their slicer…
Yeah I mean I had turned off the zhop and was getting collisions for complex parts (like NASA fabric). I turned it back on and lowered the zhop distance and it’s a bit better now. I am thinking that the PLA is soaking up water, the thing is right next to the sump pump for the house (like within 10 feet of it, the sump is in a small closet near by.
Looks like overwhelming moisture, filament is not laminating with each other, either preheat filament, try running slower print speeds and high temps e.g. 210… need to eliminate moisture.
