Stringing Since First Print  

That looks like wet filament.  Try drying it (look up threads here) and come back if problems persist.

Cheerio,

RE: Stringing Since First Print

That was my thinking, but using 3 different brand new filaments led me to believe that may not be the case. I'll give drying it out a go. Thanks! 

RE: Stringing Since First Print

Any recommendations for a filament dryer?

Thanks,

RE: Stringing Since First Print

I am using one from PrintDry for some time now and since they got new models out you might get the old one for a good price...

Many of us use food dehydrators - cheap kitchen apparatus lightly modified to hold spools of filament - you can make workshop snacks as a sideline.

You have a choice of cutting out the centre of the food trays or printing a new extra-deep filament-drying tray.

I wonder if I can make snacks in the printDry…

RE: Stringing Since First Print

All,

Thanks for your help on this.  I bought a dryer.  Initially the spool was at 57%, I dried the spool to 39% and NO STRINGS!  You all are awesome!!

Thanks again!

Jim

There are food dehydrators you can get that don't needed any modification and have room enough for several 1kg spools.  I have one with shelves that slide in/out from the front.  Just remove all the shelves (or all but one) and you have a nice large space for spools.

RE: Stringing Since First Print

i dried the filament for 4 hours at 40C. Much improved. This is 190C print temp. Do you think it's worth a second drying session, or maybe mess with retraction at this point? I'm leaning another drying sesh.

Keep drying.

Cheerio,

RE:

What diem said. And crank up the temp (when drying). Do not mess with retraction parameters!!

Using PLA, I've tried 3 different spools from two different manufacturers, all in different colors.

I have been printing temp towers to try and get the stringing under control, to no avail.

I have tried a few different retraction settings, even some extreme ones (I don't remember exact settings).

Please see images. Even 180C is showing some stringing, and I am under the impression I should be able to print at 200-215C without significant issues.

I am not sure what to do, this is my first 3D printer. Temperature/humidity of printing environment included in pics.

Included pic of my extruder - do these wires need adjusted? I am thinking yes, but again, newbie.

 

TIA
