  1. Thanks! I'll first try the "complete drain" method. And printout some tests. If it will fail again... I'll try with a new adapter. Seen available on Amazon Italy, both GS and GST (mine is a GST). The GS seems "older" but more reliable (costs 30€ more): eventually I'll go for that one. I'll keep you up to date, and thanks again!
  2. So... unluckily I've no other options here. Nonetheless.. it's quite probable is a power problem: in this case... how many probabilities it is an adaptor problem, and not a problem of internal circuitry? Consider my UM3x is about 5 years old but rarely used in comparison to the "standard": it's an home printer, not a fablab one.
  3. Thanks, CarloK. Unluckily I've no other similar adaptor at home, where I've the UM3x, but I've an Ultimaker S5 at the office: do they use the same adapter (cannot check now). In that case I could try the S5 working adaptor...
  4. I tried keeping the UM3x completely detached from the power outlet for 3 hours, and tried again: the print started but after 10 minutes of printing, the printer did reset again... with the nozzle stuck in the print (normal PETG print, with related standard temperatures). I tried again keeping the UM3x detached from a whole night (10+hrs) and the same print did complete successfully. Nonetheless... I'm quite afraid something is going bad for my printer... No ideas whatsoever from our super community? Any ideas about what more to check, so to best diagnose / address the issue? Many thanks!
  5. Would a factory reset be a worth try? What would I lose in resetting? only name + wifi connection? or even some data, such as the levels of NFC materials used?
  6. From yesterday I cannot print anymore on my UM3x: every time I start a new print (even - tried - some cloud prints that worked perfectly some months ago), while heating up the cores or - in some (latest) cases - during the subsequent auto levelling, the printer resets. I've done a sample video of the behaviour (during heat up): Tried yesterday and today... 10 times, same behaviour. The very last time it seemed to have managed to finish the auto levelling but... on the last check, it did reset. My UM3 and Cura are up to date to the very latest versions (as of yesterday). To note, it's the first time I was printing after the latest UM3x firmware update (5.3.0, coming from 5.2.16). I tried to keep the power adapter detached for 1 hour, to understand if there's a problem with the power brick. But no positive changes. During the heat up I see the led lights "blinking a bit", as if there was some power problem. I'm afraid there's something bad on electronics... How might I do? I saved my UM3 log files on attached ZIP file. Any ideas... really welcome! UM3x_Logs-2021-11-14.zip
  7. Thanks, Rachel et al. I’ve found the NFC reader/writer ACR122U based on Amazon, as well as the tags (NTAG216). I’ll try it in MacOS (BigSur) asap... Question: but having a latest iPhone (nfc write capable), with app like “NFC Tools” that can write NTAG216, might you simply program each tag with the correct ID (copy & paste from Cura) to have a similar solution? thanks
  8. Same "intermittent" problem here: Cura 4.8.0 and Big Sur 11.0.1 (on latest MBP16 2020). After importing the different stl files on plate, the only way to select them is via the object panel (very uncomfortable... ok as a precise option, but usually far better to click on an object to select it), and as soon as I try a movement or transformation, they get unselected... This could be a real problem, 'cos it's quite important to move and rescale objects... PS: one of the loaded file was not considered as watertight... maybe this scrambled something... (but the problem is minor and looking at the print preview sequence is should print OK). Anyhow I personally found that saving the .3mf file, quitting Cura, reopening and reloading the file... it works as usual.
  9. Is there any Cura setting that force the roofs (and floors) to be printed in horizontal or vertical lines (in respect to the build plate), instead of diagonal? Whenever an object has a top flat layer, the fact that Cura always prints it diagonally produces not optimal results. I understand that a diagonal print might be more resistant, but I would like having only the top 2-3 layers in horizontal fashion. Obviously I could turn the object itself 45°, as in below picture (left), and get horizontal lines, but I would prefer having only the "final layers" in horizontal fashion, while all the rest of the print keeps a more solid diagonal design. The two photos I've included show the last layer in diagonal, that - even with ironing enabled - produce sub-optimal results. Would it be possible with Cura?
  10. @gandy thanks for the wonderful explanation. I'm not an NFC expert, but if I can find some time, I'll try going through (and in case let you know)!
  11. It would be great to: 1. add the new non-Ultimaker filament in Cura DB (es. Filamentum Vertigo Starlight, with all of its data). 2. obtaing the new material identifier from Cura db 3. write an NFC tag with this identifier. Still unpossible? Given I use so many different brands materials... I'd love such an (easy) solution!
  12. I've the same problems: - there's mostly always to override a non-NFC material (see thread link) - I always get an error message: "Not a group host. You are attempting to connect to UM3X-SPP but it is not the host of a group. You can visit the web page to configure it as a group host." For the second topic, the offered URL is bad (strange they've not already corrected in Cura), but it would work if you prefix your printer IP address (eg. http://10.0.0.31/print_jobs/). The problem is that even following the link, that brings you to the normal Cura Connect webpage, you cannot change the host group. But, in any case, would I really want/need to have an host group? My scenario is this one: I've an Ultimaker 3 Extended at home (UM3X-SPP) and an Ultimaker S5 at work, in two different networks. Both of the printers are assigned to my Ultimaker account. Obviously - being in different networks (no common VPN) - the two printers cannot directly communicate one another, while they could through a cloud service. I do not really need setting up a group host to direct prints to available printers, as my works happen in different locations. How could I manage this, without having this usual message to override? Thanks
  13. Very kind, my friend! I'll do it today, as soon as I finish the current 7hrs air mask print 😄
  14. I understand Rebekah problem, and I've the same: 60% of my filaments are not Ultimaker/NFC enabled, so there's mostly ALWAYS an override to be done... really annoying. Using generic materials means you cannot use specific and "colored" non-Ultimaker materials, something that is useful for: 1. looking at correct colored parts, especially in dual extrusion 2. my materials database is detailed with specific printing options, cost, etc. In the end: --> I need using specific non-ultimaker materials --> It would be nice having a Cura option (easy to select) to override automatically. Might you please consider implementing this feature?
  15. I've finally used the official 0.25 Ultimaker printcore that I bought about 2yrs ago but never had the occasion to use before. My printer is an Ultimaker 3 Extended, last stable firmware. Last Cura 4.6.1. Problem: changing the printcore 1 from the standard AA0.4 to the new AA0.25 my printer always thinks to have attached an AA0.4. I did try changing it two times, I cleaned with alcool the printcore contacts (but the 0.25 core was brand new and enclosed in a plastic bag). Nothing. Always recognised as an AA0.4. I did calibrate the XY axis after changing the core: all did work. I did override from Cura the not recognised 0.25 and it did print perfectly, no problems (great core for details). Nonetheless I'd like to solve this problem, otherwise I must override the raised error for every print. Any idea? Many thanks in advance
