Firmware update on Ultimaker 3 Extended

[BugMeYetAgain 0]

Hello everybody.

Is it safe to upgrade the Ultimaker 3 Extended printer firmware with an Ultimaker 3 firmware file? There appear to be no U3E dedicated page on the website.

Thank you for your help!

Yes, it is the same firmware - currently 5.2.11.

Well, I know it is a different topic, but I'll ask anyway. It says "cannot verify firmware" both via usb and via download. I have 4.3.96. So I cannot upgrade.

I think you might have a corrupt USB stick or download is most likely but your firmware is quite old so you might want to use the recovery image to cleanly install the version you want.

have a look here: https://support.ultimaker.com/hc/en-us/articles/360011587199?download=%2Fen%2Fresources%2F23129-updating-the-firmware
 

and alternatively you can get https://software.ultimaker.com/releases/firmware/stable/5.2.11.20190503/recovery-5.2.11.20190503.img and follow this guide https://community.ultimaker.com/topic/20024-recovering-a-bricked-um3/?do=findComment&comment=19989

@BugMeYetAgain - it's important to have both files - the content and the signature file - on the USB.

One of my first prints failed 90% in on the new update.
