Hi all ,

So my UM 2 's nozzle was clogged pretty badly , i used the Atomic method to clean it up . I had to repeat the process many times and finally got it cleaned completely. (I could see a tiny hole from the top)

Now when i start my new prints i'm facing the following problems :

1) The PLA filament keeps wrapping itself around the nozzle while printing .

2) The print quality is really bad , i'm unable to even print a simple flat rectangle . the lines are not straight , it's just going haywire . Sometimes too much material comes out sometimes too little .

I did the build plate adjustments numerous times . . Still no luck .

My print setting are as follows :

print speed : 50mm/sec

layer height : 0.1 mm

temperature : 210 c

Here is a link to one of the prints , this one is the ultimaker robot .

can someone please help me out here ?

    Sounds like its still not fully clean. normally if the nozzle is partly blocked the filament curls up as it comes out.

    try getting a thin bit if wire and poke it up the hole then do a circle motion to try and wipe any dirt off the sides. do it while hot may help. Then do atomic again. i had to do this once to fully clean it out.

    I agree with labern. You need to find something metal and strong and rub it around the inside of the nozzle hole. I had the same exact issue and this fixed it the first time I rubbed metal around and around followed by one last atomic clean. Basically scraping off some last bit of gunk in the nozzle tip.

    I purchased some hypodermic needles (extra small) for this. Acupuncture needles also work well. Make sure they are >.2mm and < .4mm in diameter.

    Looking at the picture I don't have the impression it is underextrusion, but that the bed maybe isn't leveled properly?

    If you look at the string of filament that is being pushed out, that is hanging on a thread, the extrusion seems fine.

    I assume you cancelled the print?

    Try leveling the bed, and try to level it a bit higher as you did now.

    Hey guys . .

    Tried the following :

    1) Atomic method over and over again :)

    2) Took a very tiny needle and cleaned the nozzle as suggested by one of the users .

    3) Then i tried leveling the bed again .

    And then to seek some divine blessings decided to print Lord Ganesh.

    And http://i.imgur.com/J9BMs3O.jpg he is in all his glory

    Thank you from India :)

    You've accidentally included the smiley in the URL, but when that is fixed... looks good to me!
