Comment on [Troubleshooting] Big stringing problem with flsun SR and Orcaslicer

rambos@lemm.ee ⁨7⁩ ⁨months⁩ ago

lemann gave some good points. Since you already tried so many things like lower temp than recommended and drying, I guess bowden tube might be loose (there should be no play at all). Or just a bad filament? I know esun is quite popular, but I never tried it.

What size of the nozzle you use? Bigger nozzle = more stringing

It is hard to avoid stringing with PETG, but for PLA it shouldn’t be a problem at all. My bowden extruder with 3 mm retraction has 0 stringing with Polymaker Polyterra PLA. Even with 1 mm stringing is almost gone completely. I found Polymaker much better with stringing than DevilDesign or AzureFilm that I used before.

I know esun is quite popular, but I never tried it.

I’ve generally had the best results with it. Ironically, before the upgrades I had almost no stringing.

I’m using a 0.4mm nozzle. I probably should have mentioned in the OP that I didn’t have problems before, but the upgrades have happened in addition to moving to Orcaslicer.

Now I’m worried if I’ve got my Bowden tube seated in the hotend correctly…

  Just pull/push the tube with your hands. If there is no play you are good, but if there is:
  
  Inspect the bowden tube ends and cut them if they are worn out
  
  Push the bowden tube in the fitting.
  
  While pushing it in, press the collet down
  
  Then pull it out with a nail and then zip tie it
  
  I found original clips too thin, zip ties are much better IMO. It helped me remove stringing completely while using half of the retraction distance (using 0.6 nozzle)
