  1. Contact your reseller. There is a procedure for restoring the firmware, but since it requires to remove the bottom cover there is a danger for touching high voltage components. Your reseller can help you and use the correct procedure to meet your countries regulations.
  2. Like mentioned above, the Ultimaker printers only work on the 2.4GHz band. Trying to connect the printer to a 5GHz network will never succeed. Most likely your guest network is at 2.4GHz. Most routers that support 5GHz, also can be configured to grant access at 2.4GHz.
  3. The returned length is in mm, so just over 52m in your example. Take the number with a grain of salt. The feature is in a prototype state and wasn't developed further since the flow sensor proved to work so well. The value is an indication but I would count with a 30% margin if you want to be sure. Here a link with info on material lengths for new spools: https://support.colorfabb.com/hc/en-150/articles/360002291617-What-is-the-length-of-filament-on-your-spools-
  4. It is available in the web api of the printer but I don't think we show it in any remote tool like Cura or Digital Factory. Surf to the web page of your printer and you will find an online document about the printer's remote access functions. When you are on the same network as your printer you can enter the next line in your browser and it will show you a value which is the remaining length or -1 when unknown. Example: Replace the by the ip address of you
  5. @CWD_london Please provide more info. What is your system setup? - What printer model do you have? - What firmware version is on your printer? - What material are you printing with? - What nozzle size is mounted? - Is this a recent problem? Did it work correct before? What changed? - Did you change anything to the printer setup (moved or replaced the Ultimaker spool holder?) Many things can go wrong with the flow sensor and I both hate and love this feature. I still feel bad for the print I restarted multiple times because of a flow sensor error, only to discover
  6. You missed the first post in this thread. It has a link to a recovery image which I believe is still the 4.3.3 version. Here is the UM3 v4.3.3 recovery direct link: https://software.ultimaker.com/jedi/releases/UM3_recovery- And the recovery for UM3 v5.2.11: https://software.ultimaker.com/releases/firmware/9511/stable/
  7. I'm currently working on another project, not on the S3/S5 so anything I mention here is from own experience. The bad part is, we are using old software. The good part is, we are using old software. Many bugs have been solved since the original release and I'd like to see many of our libraries updated to newer versions. The good part is that the software is working on thousands of printers with relative few problems and most of the problems are perhaps annoying, but at least known. @Whitespace what changed in your setup for these errors to start occuring? Is it a
  8. IT-departments never cease to surprise me... With a correct DHCP configuration you don't need static ip-addresses. Your DHCP server can be configured to always assign the same ip-address based on a once configured MAC address. Then, for the host name, DHCP has an option to change the hostname as well. So, with a well equipped IT-department they could handle it all themselves instead of you having to do crazy things (and we as well). Note that RFC-1035 says the length is limited to 63 characters. So why your IT-department comes with an 18-character limit is sur
  9. You have two problems that I think are unrelated: 1) After rebuilding your printer the printer shows an ER05 for the Z-axis being broken 2) Cura 4.5 can't upload firmware from a Windows 10 computer I want to focus on problem 1 first, since when we get that working you don't mind about problem 2 anymore. There is an article on this forum where people reported the same problem when the 5V fan connector was connected to the wrong pin header. In the middle of the board is a connector marked JP3 - 8/16 step, when you connect the fan here it causes the stepper moto
  10. Thanks for reporting, it is assigned internal ticket number EM-3499 All our translations are centralized in a widely used tool. Something went wrong and for many languages the hour symbol changed to an 'M'.
  11. M190 with the 'R' option is not supported by the Ultimaker printers (at least not with the current v5.6 of the firmware). What you can do is to add a wait time: G4 S<time in seconds> We did a similar project for series production where we printed 1 PLA object and then used the print head to bump it off the glass plate. So, it is possible but we didn't cool the build plate in between prints. We added the famous blue tape to the build plate so the adhesion of the PLA was good, but weaker than when printing on the glass plate.
  12. Print times do differ between Cura versions but I know that these changes are being monitored with every release and large deviations are being fixed, unless the extra delay improves print quality. A factor 2 difference sounds like a change in settings. Can you share more info? What was the old Cura version and what is the new version you are using? What printer brand & model are you using? Can you post the model?
  13. That's not true, the used material quantity is updated quiet often in the NFC chip. You might loose a few cm of filament but that's within accepted margins. One of the main reasons we never implemented this feature is because we don't know how accurate the filament length is to start with. On the S5 you have the filament sensor which will pause your print at the end of the roll so you can switch to a new roll.
  14. Great to hear your printers are working now! I forwarded your WiFi findings to my colleagues working on the S5 printer's firmware. We had WiFi related problem reports before, but could never reproduce it. Your report gives some new details that hopefully will help find the problem.
