Geeetech uses the cheapest, crappiest plastic extruder head. Just take a look at the geeetech forum complaints about under extrusion.
If its the mk8 plastic extruder head check the tension of the arm, if the spring is weak, add shimies to compress it more. If its the heavy duty spring, dissassemble the extruder head and examine for cracks. Mine came with a heavy duty spring which had put so much force on the idler wheel it had cracked the part holding the axle. The part was hidden between the stepper and the tension arm so i didnt diagnose it for a long time. Ive removed some of the plastic which sets the gap to give enough tension even with the cracked part while i wait for a new metal extruder head.
This problem really sucks because there are so many legitimate problems which can cause your problem you can spend forever following those without realising the product is faulty by default.

Thats a nice extruder,exactly what i use. Make sure you adjust the tensioner bolt so that the brass toothed wheel bites into
the filament enough so it does not slip.
Heat the bed and nozzle,then move the nozzle to centre of the bed and at Z0 you should have about a 'fag' paper distance between nozzle and bed(adjust Z home if nessesary)
With layer height set at 0.2mm, set initial layer to 0.3 or 0.35 and initial extrusion width to about 130% (set in the slicer)
I find printing circles on 1st layer can be problamatic at times and need to be printed quite slow(10 -20 mm/s seems to work for me)

Bad news... Anything else I print with 0.2 layer height still being a disaster...
