1.75 Filament?

I bought some filament for the K8200 and i think i bought the stuff. I got 1.75 PLA and the extruder wont pull it in. Should i have bought 3.0?

I use this for 1.75 filament http://www.thingiverse.com/thing:819504
It exists also for 3mm and good for flexible filament
Have fun :slight_smile:

The stock extruder/hotend of the K8200 is made for 3mm filament.
