print quality problem

Hi,

Can somebody help me with my prusa i3 print quality, I´m using repetier host on PLA. any recomedetations with the speed, temp, fan % ? nozzle 0,5

My prints will be fluffy, why ? the bottom layers are okay but then it seems like the printer speeds up and the filament will not flow properly.

Looks like low extrusion. Is the extruder calibrated? If it is turn up the temp to see if that helps.

Also make sure your hotend isn't clogged and the extruder pushes the filament correctly.
