So, I’ve had my v3 se for about 8 months. Never had a single issue with stringing. Suddenly, I have a terrible issue with stringing. Two things have changed. One, I used up my Creality nozzles and bought a 20 pack of nozzles on Amazon. The other is I started printing with a PLA+ that is crazy tough and sticky. LIke, if it cools in the nozzle, the nozzle is trashed. This pic is with a brand new nozzle, and with filament I’ve had no issue with in the past. Creality Print software with no overrides. Yesterday I had retraction all the way up to 4 and distance up to 5, and while there was some improvment, there was still an unacceptable amount of stringing. Is it possible some of that PLA+ is jammed up in the hot end somewhere and is preventing adequate retraction? I’m pretty stumped and could use some veteran advice. Thank you in advance everyone!
PLA+ isn’t that much different to PLA. It needs to be kept dry, wet filament strings badly. It also, well usually, prints at a higher temperature than PLA, about 10°C. Don’t think your new nozzles will be that bad unless they are super cheap and gnawed out by hamsters rather than machined. I would start with giving that filament a good dry (oven, filament drier, food dehydrator etc) and run a temperature calibration. Careful with high retraction distances it can cause clogs, you shouldn’t need to go over 1mm.
Thanks for the reply Bonfireman. This striniging issue is with every filament I load, not just the PLA+. The issue just cropped up after I ran the PLA+. I run every new roll through a filament drier too. I don’t have any prior experience with PLA+, but this one is nothing like any other PLA I’ve used. It’s difficult to get off my PIE plate, it’s easily 10x stronger than any PLA I’ve used, and when I switch it out with a different filament, I can feed a foot of new stuff through the hot end, and I’m still getting streaking from the PLA+. It’ll continue to come out long into the next print. This is not how my machine runs. Again, never had an issue with stringing, and suddenly it’s all my printer can do.
i would run it with a glue layer as a release agent. Can you swap back to to any of the old Creality nozzles, just to see if it still prints badly? I don’t get stringing when I have dialled in the right temperature and it is nice and dry.
I don’t have any more of them unfortunately. I should probably pick some up…
And neither do I, which is why this has me thrown for a loop.
