Geeetech

I am a beginner. I bought the delta rostock g2s. I have it assembled and calibrated. Upon starting my first print, it heats the bed, homes, goes to 5mm and the extruder heat. After this, it raises to about halfway point and starts printing. There is also very little coming out of the extruder. Could someone point me in the right direction?

first,you should level the hotbed when you finish assembling.
then,as to the extruder just coming out a little,there's a post where you can do some trobleshooting.
