  1. Hi Patrick The S- series are reliable machines, no question about it. Also true for the UM2+ Connect. We operate them in our print farm. They do however suffer from some hardware and also software issues (can be more specific if you like .. let me know). However, we have lately come to the conclusion that Ultimakers are completely outperformed by the Bambulab X1C in every single aspect. At only a fraction of the cost. So, depending on you build volume requirements, the X1C would certainly be a better choice. Sorry if this seems out of place here. But that is my personal experience. Hope it helps. Cheers Kris
  2. Can confirm this. Out of our 12 UM2C's, four have network issues. Common response from the retailer; we would have to box up the machines and send them in for repair. I suspect a common design/engineering issue. Switching to Bambu Lab.
  3. Hi We operate 16 UM 2 connects in total. 5 of those are impossible to connect to the network. No connection to Cura possible. No matter what we do. This is a hardware/software issue no doubt. Switching to other printer brands cause the problem has persisted for month will Ultimaker not caring. Cheers Kris
  4. Oh, ok. But that used to be different. At least in my experience.
  5. Hi all Quick question: lately I keep having to sign in into Cura 3-4 times until it recognizes the account and associated printers. After a while, Gcode uploading doesn't work anymore. The messages 'Uploading print job to printer' start piling up. I then have to sign out and sign in a few times again (Cura 5.3.1). Not sure if it is an issue that only I have. Cheers Kris
  6. This is great stuff. Would it be possible to print different models sequentially? I was thinking that maybe I could stack manually in the GCode text file. But the UMC safes a binary UFP file which I cannot change manually. Cheers Kris
  7. Thanks. Not an option for this one I'm afraid. But...got mostly rid of it by changing to a Connect. Guess it uses different stepper drivers 😀
  8. Thanks for the reply. That's also what I thought. I also did a high res STL and printed it. Did not improve the behavior. Guess it is a hardware thing. UM2C turns out to be a different story.
  9. Hi I'm sure some of you have also come across this issue. Vertical lines on vertical, 2D curved, surfaces. Can this be overcome (Cura 5.2.1)? I tried a few things: high res STL, max travel resolution & deviation, speed, layer thickness between 0.06mm and 0.1mm. Nothing changed this. I guess it has to do with how the printer approximates the curvature. Cheers Kris
  10. Thank you Mari. That does help. Digital Factory is great, no issues with it. There are basically two reason to use the network: a. a lot of CGodes are written ad hoc, going via the DF slows down the workflow b. occasionally internet connectivity is an issue. Usually not a big deal, but if it happens at a bad time impact on productivity can be a bummer (e.g. if a number of printers need to be started but cannot). But thanks for your reply.
  11. Well you have proven the point. I have spelled out my subjective observation. If you disagree, fine. But would you kindly stop postulating things? Continuously... Because to me, you actually come across as aggressive and utterly intolerant. But never mind; there has been some valuable input now from an official answer, on this not official Ultimaker support channel.
  12. Thanks for the reply. I'm afraid I have tried that solution on several machines. The issue persists with 9 UM2Cs and countless S3s and S5s. But OK, I'll figure it out. BTW, at what point was I not nice? If I feel like things here have changed here, I should be able to mention it. Do not postulate that I'm not being nice, that is indeed rude. I have shared multiple experiences here over the past years coming directly from our print farm. And this has enabled people to improve their machines. And there still are issues (eg. the post I made about the bowden tube issue the UM2C has).
  13. I guess the forum isn't what it used to be...😔
  14. Hi Any idea what happened to print 'print over network' in Cura? Was pretty useful. Cheers Kris
  15. I know this post is old, but anyways. We print all high temp thermoplastics on machined ALU- plates that are machined to fit the ultimakers. Cast & machined plates that is.
  16. Hi there I have a bunch of printers set up in the digital facory. They are all ready to print, but are displayed in the digital factory as 'finished, awaiting cleanup'. Restarting doesn't help. Any idea? Cheers Kris
  17. Occasionally we do have prints that require the UM2+ extended. But with that mashine not being available in the future larger prints will have to go the S5s. Cheers Kris
  18. I just realized the only UM with 300mm z- height now is the S5. Will there be a UM 2+ Connect Extended? cheers Kris
  19. Could not agree more. Bondtechs and a bag of PTFE couplers. All my UM2(+)'s are between 3000-5000 hours now. BTW I use a little fan to keep the Bondtechs cool.
  20. Wo steht das ich sie fertige? Der Coupler ist eindeutig als Verschleißteil identifiziert. Wenn der UM2 muckt...fliegt der Coupler und es geht weiter. Aber dank der Open Source Geschichte bin ich nicht an einen Lieferanten gebunden. Ich meine den UM2. Ich rede nicht vom 'basteln'. Ich rede davon das man sich mit einer jeden Maschine die man benutzen möchte ein wenig auskennen sollte. Bei der Kettensäge kann man sonst im schlimmsten Fall nur noch bis neun zählen.
  21. Sehe ich ganz anders. Habe ausschließlich UM2's im Einsatz, fast pausenlos. Die Investitionskosten sind dabei ein Witz. Open Source ist dabei eine Grundvoraussetzung. Woher die 3000€ kommen kann ich nicht nachvollziehen, auch den DM Vergleich nicht. Wollen wir in 50 Jahren immer noch mit zwei multiplizieren? Zum Drucker selber bauen; mache ich auch. Ist aber noch mal eine ganz andere Hausnummer. Hat mit den empfohlenen UM Modifikationen nicht viel gemeinsam. Ich empfehle den UM2 grundsätzlich weiter; sage den Leuten aber das sie sich darauf einstellen müssen zu lernen. Ist aber bei Kettensägen nicht anders... Ein Kollege von mir hat sich einen zugelegt. Der Zusammenbau war in einem Nachmittag erledigt. Seit dem druckt er lustig. War sein erster Drucker. Klar wurden die 'Plastikteile' mit einem 3D- Drucker gedruckt. Dafür sind sie ja da
  22. Was kostet so ein Fortus denn? Und was kostet so ein Kilogram Material für das Maschinchen?
