Filament feed rate? (2 replies)

Whenever I start a print, the filament doesn't extrude within the first 3 seconds of the print. The filament comes out quite slowly and only touches the bed around the 4th second of the print, causing the filament to curl up and not really stick.

Is this because of the feed rate? Or is it due to other problems that I'm oblivious about? I'm very new to 3D printing, so much more to learn. As for now, I'm pretty much stumped.

I'm using a Printrbot Jr with Pronterface + Slic3r
