Today I had a problem with one of my prints, My print stopped halfway, and there was some under extrusion. So I decided to clean the nozzle. Someone shared an amazing way to do so with me a little while ago, and I would like to share it with you. It works really well. It might me a well know way to clean your nozzle, but I made a simple guide anyway. Here is the link to the post http://3dyi.net/um2-nozzle-cleaning/. Hope you like it, and it helps someone in a moment of frustration.
Tips are welcome of course.

Mmm … it seems the same of the old and very famous (among the users of UM2) “Atomic Method” … here : The Atomic Method - 3DVerkstan Knowledge Base

I think you’re absolutely right. Someone showed it to me, and I had never seen it before. I was wondering if it was a well-known way to clean the nozzle, it turns out it is. That’s a good thing I think.
Thanks for sharing, I will add the link you posted on my website.

Hi Jori,

on the same site you will find some other very useful “tutorials” for troubleshooting :wink: As as I have said … is quite famous between the users of the “Ultimaker user forum” (http://umforum.ultimaker.com/).

Have a nice day,

Yea, I browsed through the site a little bit, very helpful. I can imagine it is well-known. Thanks for pointing it out.

Kind regards,

Sounds great. You can also make your nozzle a bit larger from 0,4mm to 0,6mm and you will never have any underextrusion again. Also you can print faster.

It looks good! We have actually had Alex posting one here : Talk Manufacturing | Hubs . It’s pretty detailed , but it covers a lot of the possibilities as well. I found it very helpful too.

Ive done that many a time! A speedy method when swapping filaments is to heat the nozzle up, melt the filament in and yank hard a few times. It won’t do as good a clean-out as that will but it does work great on the fly! Any Nylon filament works great for doing that as it is really gooey and runs into all the areas of the nozzle to pull stuff out.
