Probleme mit NuNus PLA

[reibuehl 42]

Ich habe mit meinem Ultimaker 2 leichte Probleme, das schwarze PLA von NuNus zu drucken. Die Drucke haben immer wieder Fehlstellen, die nach underextrusion aussehen und oft lösen sich die ersten Layer trotz behandlung mit dem Klebestift von der Glasplatte ab. Ich verwende bisher die Standardeinstellungen für PLA und drucke mit der Quick Print Profil "Normal Quality" in Cura 14.09.

Da ich mit dem mitgelieferten, blauen PLA von Ultimaker und auch mit ColorFabb PLA keine solchen Probleme habe, frage ich mich nun, ob es bessere Settings für das NuNus PLA gibt?

Hi,

Sorry i don't speak german, thanks to google translate i understand you have under extrusion with on particular brand of PLA?

Make sure the diameter of the filament is under 3mm, the recommended size is 2.85mm for Ultimaker. Some brands sell 3mm filaments that are real 3mm filaments with some variations generally going from -0.15mm to +0.15.

This will cause the filament to get more friction in the bowden tube and lead to underextrusion...

The NuNus Filament is specified as diameter 3,0+/-0,15mm, roundness: 3,0+/-0,08mm, processing temp. 190°C - 210°C.

Would it make sense to somehow lubricate the filament to lower/avoid the additional friction? If so, what would I need to use for lubrication?

Hmm, i would advise using only 2.85mm filaments.

You could use some oil to lubricate (some people use sewing machine oil on flexible filaments). Not sure if it would solve the friction a lot..
