UM 2+ Stringing

Recommended Posts

Posted · UM 2+ Stringing

Hi there everyone. What are some troubleshooting and settings you guys are using to reducing stringing? I've read a few things on it but didn't know if there was a definitive fix. Is this a common problem with the Ultimaker 2+? I've only noticed it when printing multiple parts with PLA with the .4 nozzle. I've lowered the tip temp down to 200 but that doesn't seem to be working that great. Other suggestions?

Hi @Futz34 , what are your retraction settings and what is your print and travel speed?

It would also help if you could add a photo of your stringy prints :)

Hi Sander. I've used the default travel speed of 120 and print speed of 50. I have retraction checked but I've never seen any customized settings for this. The stringing was actually worse but i grabbed a wad of it and threw it away before taking these photos.

If you use an UM2+ with Cura, the retraction settings are configured on the printer.

 

I would check the retraction speed and length. In newer firmware versions you find it here:

MATERIAL -> SETTINGS -> Customize -> Retraction

 

For 0.4 mm nozzle and PLA the defaults are 6.5 mm retraction length and 25 mm/s speed.

Tinkergnome is correct on those stats. Should I change anything to these settings or other settings? @SandervG
