Stringing around the printed piece
Hi í am wondering if someone is having this issue. Whenever i print this object í have string around in the front part the one facing the door of the printer. No strings in the back. I have no strings in anyother part or the print i runned a calibration tower with my pla filaments. I also have them dry I store in cereal boxes with silica gel and print from a creality dryer.
the profile is balance 0.20 I have an edw hf noozle. My brother got the same printer he doesnt have this problem he sent me his gcode to try and it was the same while he didnt have strings. I had printed with the door open and close different pla filaments +/high speed/regular. Cant find a way to print it right.
RE: Stringing around the printed piece
Hey,
It is an interesting case. If both printers are the exact same, might there be a difference in the nozzles scratch pattern? I know it seems weird, but tiny changes on the nozzle geometry in combination with the travel path could lead to this. On the front the nozzle travels mainly to one side while on the other side to the other. Is this correct for your print? If yes, you have different nozzle sides exposed to the outside, while the other ris pointing inward. Check for a bigger scratch on the nozzle towards the door and observe how the filament behaves when you extruder it into the air.
Please, try cleaning your nozzle thoroughly (inside and out). Furthermore, try doing an xy calibration and check the belt tension before.
I hope we can figure out the reason for this.

Hi Marcel! Thanks so much for your answer. I changed the nozzle back and forth with the one that came with the printer. I even got two EDW HF nozzles and tried both, but the result is still the same.
I’ve managed to drastically reduce the amount of stringing by using air conditioning to keep the room temperature around 24–25°C. When the heatbreak reaches 36–37°C (can even get to 38, which usually happens because it’s summer where I live and it gets very hot), the stringing goes crazy. I guess the fan can’t keep up with the temperature, even with the printer door open.
When I manage to keep the heatbreak around 33–35°C, the stringing decreases. It doesn’t disappear completely, but it does get better. I’ve tried what you suggested, but nothing seems to fully fix the issue.
I don’t have stringing with other models—at least not this much. As I mentioned in my first post, my brother got the printer pretty much the same day I did, we use the same filament, nozzle, G-code, etc., and I get stringing while he doesn’t.
Check your fan blades are clean and make sure they turn freely.
Cheerio,
