Filament "drops" falling from extruder while the head travels

[SamuTnT 0]

Hi, i'm using latest Cura 1.99 build 17112015 and i'm facing this little "problem".. it's not causing bad prints but i think that is anyway something strange, nothing similar hasn't happened until now, here's an image to explaint what i'm seeing:

what can it be??

Hi

Is retraction enabled? This is called stringing and is caused by the nozzle oozing some filament while it's not printing.

Retraction can control this, you can also increase travel speed and lower temperature and speed.

By the way be warned that the version of cura you are using is in beta and might behave strangely sometimes

Hi Didier!

Yep retraction is enabled and the values on the UM2 lcd screen are:

Retract length: 5.50mm

Retract speed: 35mm/sec

Yes i know that is experimental but i'v tried with the "old" 15.06 and with the stable 15.04 and the stringing is still there!

Try printing cooler, so material does not ooze from the nozzle during motion.
