  1. To let people with similar issues know that they are probably not alone.
  2. We have tried it all. Gave up around 2 years ago. There are around 40 Ultimakers, and only some have the issue. And Cura connects very unreliably, having to log in and out . That helps sometimes, sometimes not. Some machines will not pair at all. We gave up on the ecosystem. And it turns out other systems have none of the issues.
  3. Of course, yes there many parts to that equation for sure. However, the outcome is that Ultimaker printers are becoming unusable in terms of productivity. In particular if compared to new brands and at that price point. And, I have been trying to fix the issues for many years now without success. Bug fixing was ok in the early days of Ultimaker...now, not so much. If other machines just work out of the box without issues, the outcome is clear.
  4. Constantly not finding printers, showing them offline. Or, says 'data sent' but nothing happens. Um2+ Connect constantly loose connection. Same problems for a fleet of multiple machines. Feels a bit outdated honestly. Cheers
  5. 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
  6. 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.
  7. 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
  8. Oh, ok. But that used to be different. At least in my experience.
  9. Nothing?
  10. 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
  11. 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
  12. 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 😀
  13. 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.
  14. 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
  15. 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.
