  1. Hi When exporting a print profile, I have noticed that only a small amount of parameters are saved in the 'curaprofile' file. This seems true for both 2.1 and 2.3. Version 2.3 is even 'worse', all speeds seem collected in a simple setup 'quality type'. Is there a way to overcome this? This ruins the export function for me completely since I am fine tuning my print profiles down to the smallest detail. Cheers Kris
  2. Have you considered closing the build volume to stabilize the temperature inside? Cardboard would do for a test. I use acrylic.
  3. This is simply underextrusion. In most cases caused by a worn out PTFE coupler.
  4. Print two (one flipped by 180°). Orientation as on the first image. Connect the long edges of the parts with walls that are slightly thicker than your nozzle (to make sure they get printed, check in layer view). That way you end up with a symmetric and closed cross section. The support walls need to be machined of.
  5. Not as far as I could see. Mostly standard printers.
  6. Didn't spent much time, but here are a few images related to 3D printing. Cheers
  7. Die Glasplatten sind teilweise komplett verzogen. Einfach mal über die Kante schauen. Ich ersetze meine zumeist. Ist nix Neues, sind schon viele dran verzweifelt.
  8. Nennt sich 'underextrusion' und ist ein gängiges Problem. Wenn es ein um2 ist und kein um2+ würde ich zu aller erst den weißen PTFE Coupler im Extruder ersetzen. Hält selten länger als 200h und ist tatsächlich ein Verschleißteil. Ist meistens die Ursache des Problems. VG
  9. Moin Schon mal die Düse gereinigt? Im Forum mal nach der 'Atomic method' suchen. Ist es ein um2 oder um2+? Wir viele Stunden hat er schon? VG
  10. Sounds as if you get a new UM2 quite often... Do you just close the front (with bubble plastic?) or do you have a more advanced setup? Well advanced is the wrong word I guess. I build a door and a lid with acrylic plastic. Hinges are printed. Gaps are sealed with tape. So it's completely 'air tight'. I add a cooling fan for the feeder and another to extract fumes from the build volume. It then gets hocked up to a ventilation system.
  11. Hmm...ok. Well, first thing I do if I get a new UM2; close it. Helps to stabilize the process, no matter if PLA, ABS etc. I have thus far not encountered the problem you describe in any of those machines. I print 90% PLA.
  12. Der weiße PTFE Coupler in Extruder ist ein Verschleißteil; ich würde zuerst immer diesen tauschen. Evtl. den Feeder reinigen; die Achse des Motors mittels Zahnbürste reinigen. Hier können sich Rückstände sammeln. Zudem wirst Du mit den Standard Einstellungen in Cura nicht weit kommen. VG
  13. Maybe a closed build chamber helps to stabilize the build plate temperature?

    Colorfabb woodfill. Looks and feels awesome. Unfortunately I'm unable to get a single time out of it.
  15. Finally on holiday with a little spare time to post a few prints from last year: [print=3810][/print] [print=3806][/print] [print=3800][/print] [print=3799][/print] [print=3796][/print]

  22. Had the same issue once the PTFE coupler was over used. I would recommend changing it. Can be a standard one, does not have to be TFT PTFE.
  23. The only trouble I had were caused by this: lever problem Caused underextrusion for me... but who knows. You need to open up the feeder to check, which is not a big deal. Cheers
  24. I need my machines running 24/7. Makes me pretty pragmatic when chasing a solution to a given problem. I am sure Ultimaker will find a more elegant solution But this seems to be a true problem. The only one I could find so far. To bad my primary suspect was the coupler and I threw it away :( Although it looked just fine after 500h. Cheers
