[Uneven PLA extrusion]

Greetings, done the atomic method several times. Extrusion of PLA filament still seems problematic. Here is a photo of print results. It seems to be uneven extrusion. Any suggestions are greatly appreciated.

[Stuck PLA filament]

Thanks for the reply. i was trying to be cute with "Atomic Bomb". I use this term because it seems like the last report "nuclear option" for poor extrusion. I used a higher temp and removed the filament. I did the Atomic Bob clean a few more times but I still see uneven extrusion. I attached the following image to illustrate the resulting print Any suggestions are greatly appreciated.

 

[Stuck PLA filament]

Greetings,

Our school has the Ultimaker 2

I did the Atomic Bomb cleaning method whilst using white PLA. The filament is now stuck and will not retract. Any suggestions will be greatly appreciated. Thanks.
