S5 Cura Updated and FW Question

Recommended Posts

Good evening.


This evening I updated Cura to 3.5; no issues and then I checked the S5’s FW. I selected the one that showed stable version and the process proceeded. It downloaded the file and then began updating; an hour later it was still in a holding pattern so I looked within the forum and it was suggested to turn it off and let it reboot. Once the printer has rebooted I tried the FW update again and it downloaded the file and once again after the installation began it did the exact same thing; sat for an hour doing nothing; why?


Could it be that the latest FW is already installed and there simply is not a confirmation given?


The present FW is


How can one tell if this is the latest version?


Thank you

If your Ultimaker S5 is connected to the internet it can check if there is a new firmware version is available. 

Whether or not you are on the latest version, should never result in a lagging installation. 


Could you try to install the new firmware again? Is your Ultimaker S5 on all the time, or do you also turn it off occasionally?

So you have no possibility to get into the main menu?

What happens when the printer does not have an internet connection? If you have it on LAN, it's easy to test, on WiFi, you maybe can switch off the router/access point or move the printer somewhere outside the range of the router/access point.

I am sorry that I was not clear.


When I select “latest” FW it downloads and shows “installing firmware” and then it stays in the installing screen ... forever; LOL.


I then have to turn it off and it will reboot and operate just fine. However, if I attempt the FW update again it does the same thing.


I have tried this on both WiFi and LAN. In addition I have performed the returned original function and reset Cura function.


For what it’s worth; when I initially brought the printer online it performed a FW update so I am beginning to wonder “if” because it appears to have the latest FW ( that the system does not know how to deal with it.


It remains my opinion that when in the FW area it should present if it’s the latest FW and if yes then offer a refresh option. As it is now to simply look at the screen there is no way of knowing whether the latest version or not.


Thank you all

Thank you for the suggestion; it’s a good idea to do so as it will mark all 3 FW updating options off the list with an outcome.


Regardless, it does not change the fact that the printer when connected to the internet is unable to make you aware whether the FW is installed. To me this is odd as descrete data is being collected automatically by Ultimaker.


I will share the results of the USB test.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
