Globs/Nubs Around Infill Ribs - Why?

[dlavanway 0]

Hey all!  Just got an Ultimaker 2 Extended + and I am noticing some little globbies that are happening around the infill ribs.  

Any ideas to eliminate them for a cleaner print?

UM2E+

Cura 15.04.4

Layer = .1

Shell = .8

Retraction Enabled

Bot/Top layer = 0.8

Fill = 20%

Print Speed = 50 mm/s

Brim Support

Nozzle = 0.4mm

Nozzle Temp = 210°C

Buildplate Temp = 60°C

Travel Speed = 150 mm/s

Fans 100% after 5mm height

Min layer time 5 sec

Thanks for your help ahead of time!

this is from travel moves from hole to hole. The nozzle does not lift or retract and the oozing material hangs on the infill on the travel path.

In the layer view you can see them as blue lines.

So this is normal? Is there a way to minimize it from happening?

it's hidden anyway, unless your model is really translucent. Then it useful to tick the 'infill prints after perimeters' in the expert settings.

And you could experiment with your temperature, trying a bit colder, so the nozzles oozes less. But be careful for under extrusion.

Thanks Peggy!

I think you're right that ultimately it doesn't matter since it will be hidden. I guess I was just being picky about part quality

Appreciate your help!
