  1. You can try a draft shield with limited height (it's in the "Experimental" section). If you set the x/y distance to the same value as the skirt distance, it should come close to what you want.
  2. Well, the manufacturer shows it on the product page in red and provides a technical data sheet that is offered in the download section... I would say: it's not that hard to find... (1.26g/cc - determined according to ISO 1183) Edit: ok, it's probably not the manufacturer, but one of the first results on google... ? Thibra3D datasheet: http://www.thibra3d.com/media/wysiwyg/producten/datasheet_thibra3D.pdf
  3. And in addition: keep in mind that not only the nozzle will wear out but also the transportation wheel of the feeder (this doesn't take long if you use e.g. carbon filled filament). It depends on your use case, but (perhaps) consider a change to Bondtech feeder as well.
  4. Great! I think the profile does not contain something fancy. For reference: 0.4 nGen.fff.zip
  5. yeah - i guess, I'm still not sure, what your "bending goal" is...? The wider part is much shorter too and therefore stiffer and it's harder to bend of course. I needed some tools this time... I'm sure, i can break it with a bit more force, or if i clamp it down on a smaller support area, but until now it's still in one piece... ? I think, if you need even more flexibility than this you should try PP, nGen flex or TPU
  6. The firmware files for UM2+ and older Ultimaker printers are included in the Cura installer, there's no separate download page AFAIK. If you have Cura installed, take a look at the installation folder ...../resources/firmware. At least that's the case for the Windows version, i don't know if it is the same location in the AppImage? The firmware file for UM2+ is called "MarlinUltimaker2plus.hex" If Cura is not installed, you can download the Windows setup file for Cura, open it with an unzip-tool and extract only the file(s) that you need.
  7. Here it comes, part printed on UM2+, bend and twisted. It loose its shape a bit after this torture, but doesn't break and can be easily bend back to the right shape. Pictures were taken in the shown order:
  8. Vermutlich ist in Cura immer noch der gleiche (alte) Drucker ausgewählt, oder Du hast die neue Firmware noch nicht installiert? Falls das so ist: Du hast jetzt das "plus" - Modell und der Feeder hat eine (Getriebe-) Untersetzung. Dafür muss der Motor anders herum drehen. Aus diesem Grund haben die "plus" -Modelle ihre eigene Firmware-Version. Die wird aber nur installiert, wenn in Cura auch das richtige Modell ausgewählt ist. Im Text ist das besser erklärt als im Video... Aber beachte: das Firmware-Update führt in diesem Fall zu einem impliziten "Factory Reset". Wenn Du eigene Material-Profile im Drucker angelegt hast, solltest Du sie vorher auf der sd-Karte sichern. Alle anderen Einstellungen kann man (bei Bedarf) leider nur aufschreiben und danach wieder neu einstellen. Viel Erfolg - und nicht den Aufkleber vergessen! ?
  9. If it helps, i can try it during the weekend. Send me a PM if you can share the model and/or the factory file. And i guess i need a more detailed "folding instruction"...? ? ...but nGen is a kind of PETG too (AFAIK) - at least it's based on PETG? Wouldn't this give the same problems? Is it so super humid at your place that you have such concerns?
  10. Well, nGen is not as rigid as PLA, but far less brittle. It's is a good choice for functional parts (where impact strength counts), but perhaps not if you need high rigidity. It's a bit weird that your nGen parts break so easily. I noticed exactly the opposite... Perhaps still too much fan? Usually it prints well without fan or with very low fan settings. Have you tried other PETG? Like Ultimaker CPE? That's quite strong... My experience with HT is, that it shrinks more and has a high tendency to warp - very difficult to get it adhere to the build plate - especially for parts with a big base area. It works probably better in an enclosed printer, preferable with a heated chamber.
  11. There may be some hints in this thread:
  12. Hi Link, the retraction settings per material are a (relatively) new feature of the UM2+ firmware. The Tinker-Firmware doesn't include this (yet?). Most of the "tinkerers" do not use the material settings on the printer anymore. It's much more convenient to change the GCode-Flavor in Cura to "Marlin" and configure everything with material profiles directly in Cura.
  13. Mein Screenshot war aus Simplify3D, es gibt aber auch online gcode-viewer, mit denen Du die Datei vor dem Drucken nochmal prüfen kannst. Oder speichere einfach die Datei (zusätzlich) auf der Festplatte ab, dann kannst Du ggf. mit der Version von der sd-Karte nochmal vergleichen (sd-Karte vorher ordnungsgemäß "auswerfen" und neu einlegen). Gibt es eigentlich einen speziellen Grund, warum Du alles auf ein Raft druckst? Das ist auf einem UM2 ja eher ungewöhnlich und sollte für diese Objekte in PLA auch gar nicht nötig sein? Übrigens: Laut den Datei-Kommentaren ist Deine Datei mit Cura 3.3.1 generiert, da gibt es inzwischen schon zwei neuere Versionen...
  14. Meinst Du das ernst? Wenn das wirklich die Datei ist, die Du versuchst zu drucken, ist es kein Wunder... Der Drucker macht einfach das, was in der Datei steht... Cura lädt das gar nicht erst, weil der gcode einfach mittendrin abbricht. Und bis dahin sehen die Pfade so aus wie auf dem Bild... Ist die Speicherkarte kaputt oder mal während des Speicherns entfernt worden?
  15. Das klingt irgendwie nicht gut... Wo kommt denn der Drucker her? Wenn der neu ist (bzw. noch innerhalb der Gewährleistungsfrist), würde ich zunächst mal den Verkäufer um Rat fragen. Anderenfalls hat den Drucker entweder jemand verbastelt, oder es ist ein Nachbau. Was war denn vorher für eine Firmware installiert, vermutlich war das gar nicht die originale Firmware von Ultimaker?
  16. Mmmh, das ist als Fehlerbeschreibung nun auch nicht viel hilfreicher als vorher....? Das bedeutet, das Material haftet nicht auf der Plattform, oder was ist damit gemeint? Bilder oder ein kurzes Video könnten evtl. helfen...
  17. no, not in general. Usually I only "adopt" changes if i consider them as useful or if they are important for stability. Longer explanation: In fact I'm merging the latest sources of the UM2.1-Firmware into the tinker repository at the moment, but don't hold your breath... My printer was converted into a Mark2 (magnetic tool-changer), so that's the only firmware branch that i use and test myself. In addition: i usually don't care about the material settings on the printer, because i don't use the Ultimaker gcode-flavor anymore. IMHO it's not very useful to publish new "Tinker"-releases that are not tested at all, so it's unlikely that this will happen anytime soon... Tinker-Version 17.10 already contains the stepper module fixes and the retraction bugfixes, but no new materials. Oh, and the material change wizard doesn't do the "push forward" step... ?).
  18. Well, if the delivered firmware is still version 3.3 it is very likely that the latest firmware changes did not made it into the 3.5 release of Cura. Some more research: according to the included list of commit-ids the last change for the delivered firmware was made in march, TPLA was added in June to the source repository... I guess, you have to wait a little bit longer for a new firmware release? Besides that: the only relevant change regarding the material change wizard is a new comment that explains why the material is pushed forward right before pulling it back: https://github.com/Ultimaker/UM2.1-Firmware/blob/UM2.1_JarJar/Marlin/UltiLCD2_menu_material.cpp#L152
  19. Indeed - it tries to support the three holes further up. It's more obvious if you switch back to "Support Placement = Everywhere". I guess it's a bug (kind of...) You can add a support blocker on this side though...
  20. Das hört sich an, es wäre in Cura der falsche Drucker ausgewählt gewesen. Vorausgesetzt, Du hast das Firmware-Update über Cura gestartet? Die "plus"-Modelle haben eine andere Firmware als der normale UM2, ein wichtiger Unterschied ist die Drehrichtung des Feedermotors. Wenn das falsche Modell in Cura ausgewählt war, ist die schlechte Nachricht, das jetzt vermutlich alle Einstellungen am Drucker auf die Standardwerte zurückgesetzt sind... Die gute Nachricht ist: Du kannst einfach das richtige Druckermodell in Cura auswählen und das Firmware-Update erneut starten. Dann sollte sich wenigstens alles wieder richtig herum drehen.
  21. Sounds overly complicated to me... Why not make a pull request for the Cura repository and add the printer to the list of official delivered configuration files?
  22. The "variant" files need a change (similar to the last one). This time the "setting_version" has to be increased to 5. The beta version worked without this change, but there are appropriate warnings in "cura.log".
  23. Well, the sound is overlain by the noise from the fans - but it seems to be the normal sound from the stepper motors if more than one axis is moved simultaneously. As @Smithy said - "don't worry - be happy" ? (BTW: it seems like the "Video.zip" is actually a ".rar" file)
  24. There's a plugin for Octoprint ("Firmware updater") that does exactly this. Another idea (probably easier): You can try a legacy Cura version from 2015 (15.04.6 or older), available for download from this list: https://ultimaker.com/en/products/ultimaker-cura-software/list AFAIK Cura was not that picky back then... ?
