Do you know which parameters I need to correct in Cura to solve it ?

I have an Ultimaker Extended 2+

Thanks

Dear Stephane,

It could be caused by the nozzle moving to the next part, not retracting enough, leaving a part of the material on the outside of the surface. Some information can be found in

http://support.3dverkstan.se/article/23-a-visual-ultimaker-troubleshooting-guide

There they call it stringing and can be controlled in the setting enable retraction..retraction settings. If you look in Cura you might see (zoom in when in the layerview) tiny blue lines, with a vertical stripe ending, it means that the material is retracted.

Please keep me updated if this helps?
