Geeetech prusa i3 pro B quality issues

[organotis]

So, some basic questions.
What extruder and bed temperature are you printing at?
What is your part cooling fan set to, and on what layers?
You say you calibrated your z-axis, how? what height did you rest to?
Any other model print this way?
Did you calibrate your extruder ( i.e. make sure when you tell it to extrude 10mm, it extrudes 10mm )?

What extruder and bed temperature are you printing at?
I am using MK8 extruder.Material I am currently using is Esun PLA. Bed temperature is set to 60C. Nozzle temperature is at 228C on first layer and 225C the rest.(I know that is quite high for PLA)
What is your part cooling fan set to, and on what layers?
The fan which is on side of the stepper motor with the "heatsink" works at 100%. I do not think although that this is cooling the part.( I may also be wrong.I think that this fan is cooling the stepper motor only)
You say you calibrated your z-axis, how? what height did you rest to?
I place a caliber on the z axis on both sides between the horizontal rod and the table which the printer is on. The height was on home coordinates.
Any other model print this way?
Almost all prints have mostly same issue. Rarely a print is absolutely perfect.
Did you calibrate your extruder ( i.e. make sure when you tell it to extrude 10mm, it extrudes 10mm )?
The extruder was calibrated 2 months ago as you mentioned. Before calibrating it I had over extrusion (11mm instead 10mm)
