Hello,
I had to buy external nylon(Taulman nylon 645) because Z-Nylon wasnt available and I have striging problems.I can’t go beyond 4mm for the the retraction but I still get stringing. I tried maximum fan settings hoping it would dry the oozing so it doesnt make strings but that doesnt work either. On auto I get the same result. The spool was new and I still go stringing. I will try to dry it see if it changes anything…
So yeah, any suggestions what settings I could try to stop the strining ?
Thanks for the help !

Hello,
Did you try decreasing the extrusion temperature?
In zcodex2 file I see you set it to 250 C, but as I searched it’s printing temperature varies from 230 - 265 C.
Also make sure that your nozzle is clean before printing.

Best Regards
Yes, and it couldn’t extrude anymore. Maybe I tried something too low, I will try 245 but I dont know where you found your data…
Nylon 645
- Print Temperature: 250C - 255C
- Nozzle: any size
- Print Speed: 40mm/s
- Retraction: 3-4mm
- Bed Temperature: 55C
I got the data from here:
But indeed your information is from their official page so should be better.
I’m not able to give you much instructions for external material 
Maybe someone from the community could help you with this 
Best Regards
Yeah when I answered you I saw the mention to contact them in the shared link so I did… will see if they give me a solution.

Late update for anyone wondering, drying the spool helped with the stringing. Its much less severe but still there, its managable.
