Problems with the Extruder

[FrustratedCustomer]

Hello,

I have some problems with my Prusa i3
I picked the 1.75mm ABS Filament in the Program Repetier Host as well as a 0.4mm nozzle. When using the program, I made a unnamed setting with all the tips from the Geeetech website (e.g. setting the printing speed etc.). I used ABS at 240°C Extruder Temp and 80°C Bed Temp. Still, all I get is a thin, almost invisible layer for the base layer and many “worms” and “blobs” around the nozzle, but no material, or, if I’m VERY lucky, some thin, irregular wormlike structures (as you can see in the picture). The nozzle is set about 0.2mm from the bed(two times DIN A4 paper thickness).
I hope there is something you can tell me to help me (e.g. use another program or something like this) as I’m quite frustrated and close to giving up on 3D-printing.

Sincerely Yours,

Cristian Bitterling
