  1. I normally remove the bowden tube from the print head to do the atomic method. So I will heat to 230-260, insert the material, normally push some through the nozzle to make sure it is flowing good, then let cool to 80c-100c and let sit for a minute before pulling. I also would like to replace the feeder. Its on my short list
  2. Its a new machine. 150 hours of printing. All has been PLA at 220c except for 2 small woodfill fine prints (failed prints). I will have to see about getting some more teflon insulators. Just seems way too soon to have problems, I havent had the machine 2 weeks or so.
  3. So I have been having a few issues with prints, every once and a while I will get a nozzle block midway during a print that is detailed and has small parts. It seems the outside of the nozzle gets too much material on it and clogs. I can normally retract the material fine, and just clean the nozzle with my fingertip and it is good to go. However, a few times I will use the Atomic method just to make sure. I heat to 240-260, let cool to 80-90. Wait a minute and then pull the piece out. Its always tough to get out and does not look right after. It really doesnt look like most everyone elses re
  4. I did solve the problem, see my post above (It was delayed waiting approval). I dont know if that will help you out but mine was due to me being a novice and learning the machine. Good luck!
  5. So, after some reading I think I have narrowed it down to 2 problems that I had introduced. First one, I think I had the bed too close to the nozzle, this was not allowing enough material to come out properly. Secondly, I had over-tightened the 4 silver thumbscrews on the top of the nozzle assembly. Combination of those 2, once I corrected those I have been getting great prints again. Hope this may help someone diagnose in the future
  6. So I am new to 3D printing. I have had my printer for a few days now. I have printed the robot with good success and some other small things. However, whenever I try to print something larger the nozzle will block on my ultimaker 2. I am printing on the quick print settings, the default one. Bed temp is 60c and the nozzle temp is 220c. The material is the PLA that came with the USA ultimaker, I have had this problem with all 3 of the materials. It seems to print the base fine, it always starts to block when it gets to the next part when it starts the cross section, etc. I can easily choose
