Print on Ultimaker 2 is bad

[Joasgull 0]

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!!

You have underextrusion. Can be caused by a number so large of stuff. So, check that post, and if your coupler is ok. Then you can start checking everything else like hotend nozzle, extruder, endofspool tension, bowden... etcetcetc all listed here for example https://ultimaker.com/en/community/49951-filament-doesnt-always-extrude?page=last#reply-182960
