Hello, I am quite new with 3d printing. I am using an Ultimaker 2, and it worked fine for a while but eventually the nozzle got blocked and I opened it by using a needle and the athomic method. But after this, the prints have been really bad, and I have tried many different settings, adjusting the board of course, and a lot more nozzle cleaning without any success. In the attached image you see a print before the hazzle underneath, and one from after above. How can I get the ultimaker to be precise again? All tips are very appreciated!!
