  1. I tried your settings, but I got a lot of under extrusion. Finally I tried boostig the material flow to about 140% and it started printing more or less fine. The phone came out looking quite messy, but at least it sort of worked. What material flow do you use? What's the easiest way to figure out the correct setting for me?
  2. I've done some of these tests and I initially stuck to the Pla that came with the printer to avoid an unknown factors. I had a lot of under extrusion and wasn't able to figure out what was wrong until I changed to a Pla from another manufactorer, which work a lot better. The printer is a week old only. Any idea why this is happening? The grey is UM PLA and the orange is from Rs-online. Both at 230 degrees, five minutes apart...
  3. Thanks! I'll give it a go,when I have built up some courage with a few simpler successful prints :-)
  4. Could you share your settings? About to try this out myself and I'm new in the game....
  5. Got this from UM support: ---------- You simply place the ring over the nozzle tip then place the nozzle with ring trough the fanbracket. Happy printing!
  6. Thanks for your reply. I'm talking about the small white ring called "PTFE Coupler ring" which you can see is a part of the hot end pack now: https://shop.ultimaker.com/product/61/Hot-end-pack Someone at Ultimaker said it was only implemented a couple of weeks ago...
  7. How do you mount the new PTFE Coupler ring? Haven't had it before, so no idea where it goes. I guess between the PTFE coupler and the hot end isolator, but which way?
  8. Why couldn't UM just provide some Cura profiles for their filaments? Other filament manufacturers do so for their machines...
  9. Ok many thanks but questions remain... - TG ? - Strength to chemicals ? - optimal print setting ? Have no idea. I'm an amateur in this game, so I'm starting to think this spool won't the first I try out right now...
  10. I got this info from Ultimaker support: ---- Printing with CPE has its pro's and con's, please see below: Con's: You need to print CPE on higher temperatures just like ABS. (240/250) Printing on higher temperatures will cause the PTFE to wear out faster and that is why we included one when you purchase a spool of CPE. CPE has just like ABS the tendency to warp, a heated camber may help reduce this. Pro's: CPE is just as strong as ABS. It does not have any dangerous fumes or strange odeur. It has nice bright colors.
  11. Hi Thanks for replying. I got some help on the online chat. Unfortunately I can't remember what settings I had. However I seem to have solved the problem by cleaning the nozzle with the atomic method from 3dverkstan. I'm running a print now and hopefully it will pull through...
  12. Hi I got my first printer this Friday(UM2) and I have some problems. A print looks great for the first part og the print, then I get these problems. To me and looking at the 3dverkstan site, it looks like under extrusion, but I'm not sure. Anyone that have tips to what I can try? https://onedrive.live.com/redir?resid=cea5983aab43ab26!9575&authkey=!AGQkpXvfux7UCT0&v=3&ithint=photo%2cjpg https://onedrive.live.com/redir?resid=cea5983aab43ab26!9574&authkey=!AHDilF2vuNn8rzI&v=3&ithint=photo%2cjpg
