Stringing

I use a MK4 with either a 0.25 or a 0.4 nozzle and primarily Jessie PETG. By altering filament overrides values I have reduced stringing artifacts somewhat, but stringing still exists.

I am on a quest to find the ideal combination of PrusaSlicer settings/overrides that will eliminate string. In Printables I see LOTS of photos/models that seemingly had no stringing artifacts. 

What combination of PrusaSlicer settings do you use to eliminate stringing with Jessie PETG ?  

Not interested in a discussion on stringing, as I have read the PrusaSlicer documentation, but it does not proved specific values that will eliminate stringing.

RE: Stringing

I almost exclusively use petg. The Prusament PETG stock settings leave almost no strings for me. 

Your filament has to be dry.  PETG will absorb moisture and will increase stringing.  I recommend printing directly from a drybox.

RE: Stringing

Never used Jessie's but look at those photos with a grain of salt. I'm sure most people do what I do, clean up my models before I take pictures, at least give them a swipe with the heat gun. 

And as Brian said, drying filament usually gives me more bang for the buck than fiddling with settings.

Filament is stored in dryboxes with desiccant, storage humidity is less than 12%.

Relative humidity here in Boise is less than 20% most days.  I do not think humidity is a contributing factor to stringing.

RE: Stringing

Have you tried the Prusament Profile? 

This is on my XL which uses the same Nextruder as the MK4, with Hatchbox PETG with the Prusament profile.  As you can see zero stringing.  I get the same results on the MK4. 

I print directly from my drybox.

Thanks Brian. Just did a compare value for Prusament PETG and Jessie PETG, several differences noted. Thing I will try a test print using each profile see if there is a difference in stringing.

Ordered a filament dryer, hopefully it will lessen some of the stringing
