  1. Hello, I have a Ultimaker 3 for 3 months. I have a question about the lubrication of the axes of the Print Head. The manual describes the lubrication of the XY axes, but nothing is mentioned about the axes of the Print Head shown in the picture. What is the lubrication procedure about those axes? Do they need to be lubricated as the other XY axes? Thank you
  2. Does anyone knows if it´s possible to create own nfc tags for the UM3? The tags from the UM spools can be read from my Samsung S7, but the data format is unknown.
  3. Ich könnte vergleichsweise günstig einen Ultimaker 3 mit 1500 Betriebsstunden kaufen. Was sind eure Erfahrungen was die Langlebigkeit der Ultimaker angeht? Muss ich mir da schon sorgen um Board/ Mechanik / printcores machen? ich kann überhaupt nicht abschätzen was „alt“ bzw „jung“ bei einem Ultimaker bedeutet. ich fahre einen vw Bus t4 mit 400.000 Kilometer auf dem Tacho. Das kann ich einschätzen ( das Ding ist am Ende und jedes volltanken ist ein Risiko ). ich wäre dankbar über euere Erfahrungen wann die Ultimakers unzuverlässig werden. Vielen Dank
  4. Good afternoon, Hello to everybody! I'm writting here because the last few days I've been having a lot of issues with breakaway clogging. I was printing a part that lasted 3 days and when it had printed pretty well for one and a half days the breakaway got clogged. I did the atomic clean up, everything seemed to work fine, but two hours latter the printcore got clogged again. I've tried many things, cleaning, changing parameters in cura, changing the spool to another location, ... but any of them worked. I finally changed the printcore to another
  5. I am reading about metal printing lately and i feel i do not understand fully the so called "debinding" process. I understand it is the process of separating the polymer from the metal powder once the part is printed. Then sintering is aplied to the remaining part. But, debinding is a chemical process or is it some sort of heating process as well? By the way, if anyone reading speechs Spanish, which is the proper word for debinding and sintering in our language? I am trying to find outsourcing services in Spain and have found none, probably because i do not use the right words
  6. Hallo zusammen, Nachdem ich jetzt seit Kauf meines Ultimaker 3 mit dem original Filament soweit zufrieden war und von PLA, PC, CPE, Nylon, TPU alles mögliche mehr oder minder zufriedenstellend gedruckt habe, dachte ich mir, ich müsse mal andere Filamente aus dem Marketplace ausprobieren. Ich dachte mir, was soll schon schiefgehen. Leider musste ich enttäuscht feststellen, dass es halt doch nicht so einfach ist. Ich habe etwas Filament der Firma FormFutura gekauft, da es gerade im Angebot war und mit dem rPet Filament habe ich große Schwierigkeiten, so g
  7. Bonjour, cela fait quelque temps que je n'ai pas utilisé mon UM3. J'utilise le plateau en verre d'origine. J'ai lancé un calibration de la hauteur du plateau, qui semble s'être bien passé. J'ai l'option "jamais calibration" Je lance une impression avec cura 4.7.0, la buse se trouve à 5 mm plus haute que le plateau.... Si je choisis calibration avant chaque impression , a ce moment la buse se trouve à la bonne hauteur.... J'ai même fait un "factory reset" mais cela n'a rien changé à mon problème !! Le firmware est à jour C'est comme si la calibration qu
  8. Hello I am currently printing a Badge for someone. They want the Logo to stick out at the Top and on the Bottom. Since i cant make it stick out on the bottom, i want it flat on that side. However it just looks weird. I tried changing the inital layer with to 100% but didnt do anything. Any ideas? Top image is how it looks on the bottom, bottom image is how it SHOULD look.
  9. Hi Everyone, Does anyone know how thin you can print PP on a UM3? Trying to print a thin mesh but not having much success. Best, John
  10. Bonjour à tous, J'ai eu quelques déboires avec les block coulissants sur mon UM3 qui avaient du jeu. Les remplacer est une vraie galère. Aussi j'aimerai savoir si certains parmi vous les ont remplacés par des modèles plus perfectionnés. Si oui, quels modèles conseillez-vous ? Merci, bonne journée.
  11. Hallo, Habe vor kurzem dem den ganzen Druckkopf ersetzz. Jetzt zeig er mir diese Nachricht an. Kern 1: Solex Hardcore 0.4 Kern 2: Solex Hardcore 0.4 Danke schon mal
  12. Hi, I'm new to 3d-printing so I prefer using the standard settings of Cura. Every print starts with a prime blob. I guess that's ok. But as soon as the prime blob is ready the print bed starts raising at the same time that the print head starts moving. That causes the print head (to be more precise: the bottom of the front fan) to hit the top of the prime blob. If the prime blob is PLA then it just flattens a bit but it stays on its place. But if it is PVA then the prime blob often falls down and sticks to the print head. The print head then drags the blob onto the center of print be
  13. This has rotating arms that can be adjusted to stand against different TV or Monitor thickness while keeping the shelf horizontal. I made this cause I had no high place around the TV to put my router so top of the TV sounded like an ideal solution. If you find this design useful, you can download it from Thingiverse.
  14. Hi Guys, what can I do to improve the corners of the part in the picture? I already tried reducing the speed from 70 mm/s to 30 mm/s, but no change. It is being printed on my UM3 with two 0.4 nozzles and PLA. Slicing done with Cura 4.7.1 Thanks for any advice, -pl
  15. *Sigh* here we go again; just updated from 5.2.11 to 5.2.16 and guess what... the corrupted display bug (see this topic) re-appeared. Just like it did when I originally upgraded to 5.2.11 from the versions before that. As the title states, I'm on a UM3. The corrupted display is not the worst of it, though, just like last time, the printer randomly stalls while printing (but keeps extruding), leaving me with a failed print. @ultimaker: something in your upgrade process seems to break my printer (and by the looks of it other people's printers too). Last time t
  16. Ik heb onlangs een Ultimaker S3 aangeschaft en ben erg nieuw in 3d printen. Nu heb ik bewust voor een ultimaker gekozen, om zo weinig mogelijk te moeten tweaken, maar dat is bij 3d printen uberhaubt een illusie denk ik 🙂 Maar goed, ik wilde dus proberen om de bekende emmett gears te printen (Gear Bearing by emmett - Thingiverse), maar ik heb het probl;eem dat de tandwielen gewoon met te weinig tussen ruitmte worden geprint en dus volledig verscmelten met de buitenkant. Dit probleem heb ik met andere prints ook well, dat lossen onderdelen gewoon niet lekker in elkaar passen.
  17. Hallo, wollte gerade einen Druck starten , Drucker eingeschaltet Ultimaker stand groß im Display selbst nach 2min , 4min dann habe ich abgeschalten und nun geht nur noch beim einschalten : - Die Lüfter im Druckkopf gehen kurz an - Das Display bleibt Dunkel - Das Drehrad bleibt dunkel - Die Grüne LED auf dem Mainboard leuchtet - Wenn ich das Board mittels USB Kabel an PC anschließe höre ich den USB Ton aber keine Verbindung im Cura - anderes Netzteil schafft keine Abhilfe Hatte jemand dieses Problem schon einmal, ich weiß
  18. I wanted to share a fun project I made last month. I created a smart air filtration system for a Ultimaker S3: Building an Air Filtration System for a 3D Printer https://mikebuss.com/2021/01/06/3d-printer-filtration/ I would be happy to answer any questions people have! I attached some photos of the project as well.
  19. Copied from someone else - I didn't write 99% of what is below but I think it's very useful - especially if you are messing with json files on your UM3 and it stops booting. you'll find a recovery image here: recovery.img. You can install this update by putting this image in a micro sd card - but don't just copy the file there you have to do a special process to make it a bootable sd card. here is a nice guide on putting a disk image on a sd card: https://www.hifiberry.com/build/documentation/create-sd-card-from-img-file/ If you are working with MacOS, you can better use ApplePie baker:
  20. It is often not so clear how to use 3rd party materials with the UM3 or S5 printers. So I want to give some hints and answers to the common problems and questions. Ultimaker materials Ultimaker materials come with an NFC tag in the spool and the printer is able to read the NFC tag and can detect the material and color during the loading process. Internally the NFC tag contains a unique ID which is then matched against a material database or something like that in the printer software. So if you have loaded UM material which was automatically detected by the printer, then
  21. Hi, I loaded a model and did all the settings and added support. However when I preview it, only the support will be printed and not my model. Here are pictures of 3.4.1 and the STL file. Thanks so much in advance!test 2.stl
  22. Imagine printing a 'T' shape. The skin for the current layer is printed along the middle of the T (|||||). So as it's printing there's a short up and down path at the top of the T, and a long up and down path through the main part. When printing the short path, constant back and forth, it's too thick. When printing the long path, it's too thin. I assume this is what linear advance/flow compensation is for. But I've experienced this to some extent with just about every printer and material I've owned. The printers that support linear advance seem to have minor improvements, b
  23. 1. Bei meinem UM3 verschiebt sich die Druckkopfstange und zwar die wenn man von vorne schaut die quer ist. Das bedeutet das die Endabschaltung nicht mehr betätigt wird und der Drucker einen error 17 ausgibt. Ist jetzt schon zum 2. Mal passiert, kann man etwas dagegen tun? Die Stange ist geölt und sauber. Tschau Uwe
  24. I purchased the DDG Bondtech extruders due to worn out feeder wheels from abrasive material. My issue is I am having difficulty getting in to change the new updated firmware; 5.2.11 that is now installed. I have followed Bondtech's instructions; https://www.bondtech.se/wp-content/uploads/2018/08/Bondtech-DDG-Ultimaker-V2.0.pdf I am on page 10 in this manual and I am successfully connected to my UM3+ printer (in developer mode) and there is no command line associated with my 5.2.11 firmware download. The manual offers to copy and paste one of the command
  25. Hi Ultimaker & Community. So, to put it simply, two of my UM3 printers' quality is not what it used to be. They have both done their fair share of heavy printing, one of them non-stop for years. They still produce nicely looking models but not as a new one out of the box. Let's talk about bringing it back to perfection, after all, motor steps do not rust. The natural though is to replace several parts, one by one, while printing the calibration cubes in between. My question is, what would be the right order - from most important to least important. I hope this lis
