problem extruding PLA Prusa i3 Pro B

[mrpasquale970]

Hi guys, it's about two months now that i have a huge problem, i have also changed the extruder but the result is still the same as you can see in the picture. What am i still doing wrong?
The melting temperature is fine, the plate is more or less balanced: more or less because i have tried lots of position like far away the plate, very close, touching the piece of paper used.. there is no way to make this print work over 30 minutes.. the small pieces are really fine but as you can se if i want to print this fam mount all goes wrong

Looks like a layer shifting issue,have you read this guide?

It looks like you have a case of under extruding and printing at too low a temp?

Have you checked to see if you are getting the correct ammount? If you have it print 10mm are you getting 10 or something less? If you do a search on Extruder calibration you will find several posts. Here is a link with a video.

One other thing to check is the speed you are printing at. Printing too fast will exagerate any flaws in the pirnt or calibration issues.
