  1. Hello Everyone I finally manage to print the whole file (a bit over 6 hours printing) twice! Cloakfiend Thank you for the insistence on repeating the Atomic pull. I kept doing even after it was coming out clean and after 3 or 4 times it started coming out a bit dirty again. Qmaker I also want to try different options to hold the filament spool. Cutting the right size of filament and leaving it loose works but its not ideal. Please let me know if you find a solution that you approve. I can not really point out what the issue was since I have: - Replaced the feeder - Got the filament
  2. Hi Labern, I went into a crazy spiral of information yesterday after clicking on your link hehe. I spent hours reading hundreds of posts. I haven't tried to print my file again but here is the present status of my battle: - I put the head of the print apart, cleaned the nozzle with acetone and replaced the PTFE coupler (it wasn't necessarily deformed but it was quite burnt on the bottom) - I did the Atomic method a few more times, so now the nozzle is super clean - I Unrolled and cleaned all the filament spool (right now I have only the UM PLA silver) - I cleaned the Bowden tube, cut the
  3. Hi Thank you for the fast reply Labern, Yes the filament is being drastically grounded on the feeder and because of that I had to clean the Bowden tube a couple times. Someone mentioned the PTFE coupler in the previous post but we discarded the idea because the printer has very few hours of use. But how can I check the PTFE coupler to make sure it is in good shape? Robert, I did post on the previous one a couple days ago but no one replied and that is why I decided to start a new one. I'm sorry the ignorance but how can I be sure that the back fan is running? I can clearly see the 2 si
  4. Hello Everyone, I'm posting this again because I couldn't solve my problem and I stopped getting replies from my previous post. I hope this is ok. This is the post: processhttps://ultimaker.com/en/community/17759-extrusion-stops-half-way-through-the-printing-process Right now I'm trying to figure out why the printer stops extruding every time I'm printing half way through a job that should take 8h to print. It has stopped in different stages of the job but it printed successfully for at least 3h and then stopped. I have gone through all the suggestions given in the previous post: several
  5. Hello, I need to relive this post and I really hope this time someone can help me to solve the issue. I stopped trying to print this project and the printer wasn't being used since the last post. Today I got back to it and I already have two failed prints that stopped printing after over 3h printing. The half way results I got are very similar to the previous pictures I posted here. I did the Atomic pull several times before starting again and I also did it after the last print. What I found odd was that after it stopped printing today I did the atomic pull and on the very first try it c
  6. Hello, I have tried to print again and the extrusion stopped after almost 5h printing. Here is a picture of the result: I used the same parameters and same material. After it stopped extruding I did the Atomic pull a few more times and the filament was coming dirty again. However it looked more burned than anything else. Yellowshark. After reading your reply I realized my mistake before. I was heating the nozzle up to 190, since that I was using PLA and that was what I read in the forum. I didn't think that since the clog was from ABS I should heat up to 260. That would explain why I c
  7. I did again the Atomic pulls, and as I expected it was coming dirty again, but 8 times later this is what I got: Regarding the parameters. These are the latest ones I used: I haven't changed much from the default settings. I already changed the minimal extrusion before retracting. This is just to show how it was before. And this was the first time I opened the expert configurations settings. About the feeder tension. The indicator is at the top. Regarding that indicator I have another question. I have tried to change manually but I couldn't. Is it just the case that it is really hard to
  8. Thanks for the fast reply Didier When you say several times, what number you have in mind. Every time I had to unclog the printer I did it like 5 times in a roll. We got the printer just a few months back and I don't think we have printed more than 150h. Just by looking the teflon coupler looks in shape. To be honest I just notice when it stops after some time - when I can see the gap between the nozzle and the print. What happens as expected is a lot of grinding on the back but no marks on the print it self. I wouldn't say there are more retractions than I used to see prior to this proble
  9. Hello, Recently 4 out of 5 of my printing attempts have failed because the extrusion stopped half way through, after 3-4 printing. I am working with a file to fine tune the print (changing the file itself and Cura settings) and the majority of my prints have been wasted because after hours working properly the extrusion just stops. I am particularly concern because I had to do the Anatomy pool almost every time I tried to print. As far as I understood from the posts I read in the forum that is not normal. A few weeks back we had a lot of clogging issues due to using PLA filament after ABS f
  10. Hello Anool, We are also based in India and after trying some really bad filaments from random brands we have been trying to buy better quality filaments without importing them. Please let me know if you know any good seller.
  11. Hello, I will get a little bit out of topic here. We are building a stand for our Ultimaker 2 at office, mostly to keep it safe from dust, since here that is a serious issue. My doubt is about the need of ventilation during the printing process. We designed a case that is about 600mm by 530mm by 530mm (h/w/d) made out of acrylic and plywood. The idea is to always keep the printer inside it, even while printing. Do I need to provide any ventilation system for when its printing? I didn't want to keep any ventilation slits because of the dust, but I worry that the heating of the printer might
  12. Thank you all. That was really helpful. Just one last questions. If I use it every couple weeks, is it enough to keep it "oiled"? I don't want end up lubricating the shafts and the rods too much.
  13. Hello everyone, We acquired the printer not long ago, however we are not having time to use it as often as we wished. We were wondering if there is a maximum time to "not use" the printer so we can do maintenance accordingly. eg: is recommended to run the printer at least once every two weeks. Thank you
  14. Hello, I have been using the Ultimaker 2 for less than a month now with Cura 15.04. So I don't think my issue can be solved the same way but what Braddock describes seems to be what is happening with me. As I'm still learning the best ways of using the Ultimaker I keep trying different settings and many times they fail, when this happens I usually abort the print and start again with new settings. Lately (since I started using ABS, I don't know if it is a coincidence) every time I abort I have to retrieve the filament and feed it again. What has been happening is that when I abort it retri
