  2. Hi, first point, i suggest you turn your text-color to an eye-friendly black, als this (50%?) grey is very hard to read (no offend, just a proposal) ;-). This flat nozzle tip IS unusual and absolutely not correct. It reminds me to reports of other people, who printed with abrasive materials, which eroded the nozzles and made them unusable (that's why hardened steel nozzles and ruby nozzles, like the CC Printcore, exist). The tip of your BB Core looks as it should be. So, in my oppinion, the worn is to be replaced with a new one. Usualy the UM3(E) is shipped with two AA cores and one BB Core. Is the second AA still available? Greetings.
  3. Bonjour Je possède les deux machines, et mes deux machines partagent les mêmes programmes UltiGcode de Cura (15.04.06). Une vielle version de Cura. Jje sais, mais je ne pense pas que cela change avec la dernière version. Fred
  4. Today
  5. Hello @thopiekar. I just tried the new Cura plugin for import Freecad files and now it works all right. Thanks for your work. I'm just a little confused (my mistake) in finding the right files to install. the right place is https://thopiekar.eu:5443/cura-cad-integration/CuraFreeCadPlugin/-/jobs/1024/artifacts/browse but I tried https://thopiekar.eu:5443/cura-cad-integration / CuraFreeCadPlugin / by mistake. The version number is the same (0.3.0) and is the same in the Freecad marketplace. Personally,so far, I had solved with a macro in Freecad that generates the stl file and launches Cura, but the Cura plugin should be better
  6. Hello 3d printers, I make you a brief paragraph for the history: I recovered an Ultimaker 3 Extented which was neglected by his buyer who did not want more (an unscrupulous industrialist). He gave it to me saying that it did not work anymore ... Anyway, I decided to make it running. So I reset it, get started, configured, etc ... However, I have a problem with the next one raised by the printer: "The difference between the detected height of the two printcores exceeds the realistic values". Indeed the error is raised when I want to make an print or even make an XY calibration. I checked, the nozzles were not clogged, I cleaned the tray and made a leveling adjustment manually. However, still no way to print ... Then I discovered that my nozzle AA - 0.40 was unusually flat (Attached some photos as evidence). I thought maybe it was the Ultimaker design, but looking at the new ones on the shop, I see them more conical. Mine seems to have been ... damaged ?! I would like to have your opinion ... Do I have to buy a new print head? Can this flat nozzle be the cause of this error? How does the utimaker 3 detect the tray exactly? Is the probe inductive?
  7. I just did the same using these instructions. Easy to do, works great. There's a little bit of an uh-oh moment where it looks like you need to create a debian login on the LCD, but it just moves past that after a bit. Back to using my printer as it should work. Thanks mikkermik!
  8. And your plugins make Cura work better for a lot of people I bet. My favorite is the z-offset. Thank you for them.
  9. See my post below on using 'Outer wall inset'. Horizontal expansion essentially just scales the whole design bigger or smaller. 'Outer wall inset' move the outer wall in toward the inner wall a set amount to compensate for a line width that is slightly larger than what you specify.
  10. Thank you i will try
  11. how did you sign in so you can restore your profiles? im using the same version of cura i was before so it should be extremely easy but somehow i cannot for the life of me figure out how to find out where i can restore my backups
  12. Unleveled bed leads to two extremes: nothing leaves the nozzle, or nothing sticks to the plate. After levelling, how do you know which way you've gone? Well, you print something. So give about 1 minute for the leveling process, the time an autolevel takes plus the time it takes to print something simple, and you end up wasting a lot of time. So cut it short: Incorporate a simple option to print a test square with diagonals from the tail end of manual levelling. Thus flow becomes: Manual Levelling > OK > Back position > Front Right > Front Left > Z-Offset > Auto-Level? > Test Print? > Repeat? It'd be really helpful to have the print try and print a couple lines, at least, after levelling. I'd personally be inclined to ask the user questions that would help me adjust the offsets.

  14. Ultimaker 2 for sale. $1000 Clean and prints great Only 348 print hours Photos include a 2 hour print I did today Will ship in Ultimaker box Sale includes a sealed spool of filament - Ultimaker brand PLA Silver Metallic. I have another printer and have decided I only need one One day a UM5 .... fingers crossed.
  15. Hello. Recently, I bought a Duet3d ethernet for my JennyPrinter3D (Ultimaker 2+ extended clone). I decided to change the original board, which was rubbish, for this one. It looks great and the webpanel is incredible. I am trying to configure the new board with reprap configurator but it is a little bit complicated. Could anyone share their parameters? It would be very helpfull. @Neotko I saw your video of Duet Connection in Youtube. It was very useful (me fue muy útil y está todo muy bien explicado). Regards!
  16. Bonjour à tous, Je découvre le fil de ce forum suite au même problème rencontré aujourd'hui. Pour l'historique, j'ai récupéré une Ultimaker 3 Extented qui a été négligée par son acheteur qui n'en voulait plus (un industriel peu scrupuleux). Il me l'a donné en me disant qu'elle ne marchait plus... Quoiqu'il en soit je me suis mis en tête de la faire marcher. Je l'ai donc réinitialisé, mise en route, configurée, etc... Cependant je me heurte au même problème que @Boisdevesys, à savoir "La différence entre la hauteur détectée des deux printcores dépasse les valeurs réalistes" . En effet la même erreur est levée quand je désire faire une impression ou même faire une calibration XY. J'ai vérifié, les buses ne sont pas bouchées, j'ai nettoyé le plateau et ait fait un réglage du nivellement manuellement. Cependant, toujours pas moyen d'imprimer... Puis j'ai découvert que ma buse AA - 0.40 était anormalement plate (Ci-joint quelques photos comme preuves). Je me suis dis que c'était peut-être le design Ultimaker, mais en regardant les neuves sur le shop, je les vois davantage coniques. La mienne a l'air d'avoir été... Limée ?! J'aimerais avoir votre avis... Dois-je racheter une tête d'impression ? Est-ce que cette buse plate peut être la cause de cette erreur ? Comment l'utimaker 3 détecte le plateau exactement ? Le palpeur est-il inductif ? Merci d'avance pour votre aide, j'aimerais éviter de jeter un si bel objet !
  17. @MadCooper There seems to be something missing in your code for your pyd file. Cura (actually the embedded Python interpreter) should be able to pick it up normally. I've embedded PyWin32 into my CAD plugins and it comes with many pyd files and works fine. You probably want to take a look into SWIG or Cython to be able to code with fewer hassles and let one of these projects generate the C/C++ code you need. Maybe this is something for you! 🙂
  18. Here another thread, but for the OpenSCAD plugin. Would be great if we as a community could come together here and discuss new features and current problems with the plugin. Looking forward to interesting conversations! 🙂 Website: http://thopiekar.eu/cura/cad/openscad/
  19. Hello @RobyRob and @WielGeraats, I don't know why, but I either overlooked the notifications about your posts in this thread in my inbox or I never got them. Anyway, I added an official thread as for all the other plugins. Now something that might be interesting for you: I also faced the problem in the meantime and fixed it for me. It would be great if at least one of you could test the unreleased plugin. The download link and an (updated!) installation guide can be found in the official thread soon! Regards - Thomas
  20. Here another thread regarding one of my plugins. As I see not too many discussions about the FreeCAD plugin so far, I would like to advertise to use only this thread for discussion. This way many users can meet at one place and help themselves or I can give support of course, too. PS: I noticed a bug in the plugin that will merge all bodies of all objects in a CAD file. If someone is interested to test, please let me know.

  21. This should work now. Just update to Cura 3.7.0 or 4.0.0 and update the plugin.
  22. Got tired of waiting, so I rolled back to 4.3.3 by doing the firmware recovery (attached). It was actually fairly simple, and I'm not particularly technical. Anyway, every issue is now gone, and I'm back to printing. Work Instructions Ultimaker 3 firmware recovery.pdf
  23. Thanks for these suggestions. I have been trying different speeds and slowing it down seems to improve the surface but I'm still getting spiral ridges. I'll try different layer heights.
  24. No problem 🙂 Grad to hear that it works!
  25. Hey and greetings again... do you have any news regarding the fixing of the automatic levelling problem? I still don´t know what exactly is or could be wrong with the UM3... Can I take other steps to eliminate the printbed from stopping half way to the cores and then don´t even touching them? It is pretty sad that I can not use the printer anymore now for almost 3 weeks and there is no clue what I could do to search or narrow in the problem.. See you and have a nice easter holiday Greetings Daniel
  26. Hi UM experts, I have a UM5 and am trying to get the best quality prints for architectural models. The larger scale models, 1/16" = 1'-0" print fine, but the smaller scale, ~1" = 50' does not. A photo is attached. Left print is at .1mm height and the right is at .2mm using pla. Are there particular setting I can adjust to stop the blobs on the piers between windows? Is the detail level/size of the piers to small and thin to get a good print? Thanks, John
