Ultimaker 3 suddenly no display and unresponsive button

Recommended Posts

Posted (edited) · Ultimaker 3 suddenly no display and unresponsive button

Out of nowhere the display remains black when turning on my Ultimaker 3. The rotary button does not light up. Even after 4 minutes nothing happens. Clicking the rotary button does not trigger a sound.
I do notice when I turn it on a fan briefly spins and a red light turns on on the bottom near the LAN port.

I can't find it on my local network (It's connected over ethernet).

Nothing special happened before this happened. I've used the machine a few days before without any issues.


I didn't find any related topics on this forum.


I've never done this before, but I've removed the panels on the bottom too see whether there was something weird going on.

I notice that on the bigger PCB there is also a green light on, next to "NC".




I'm in contact with UltiMaker support, who advised reinstalling the firmware following Firmware recovery: Ultimaker 3.
I've tried this, but the leds don't respond as expected, not like the 3 possible states described in the manual.
At the beginning I'm turning on the Ultimaker, after ±9 seconds Led 1 blinks (but not really slowly). Led 2 and 3 just stay on, even after many more minutes. See video:


The display indicates that it's installing firmware, and that there are 2 minutes remaining, but even after 15 minutes there is no change. The display stills shows this message, led 1 is off, led 2 and 3 remain on. At least we know the display itself still works.



I tried redownloading the .img file, using a different micro SD card writer, I used a different micro SD card.
I'm running a Linux distro (Ubuntu derivative), so I couldn't use Win32 disk imager tool or the ApplePi-Baker app. I used Balena Etcher, which is a super common way to flash SD cards.


it's like it's stating with the firmware install, but doesn't finish and without going into an error mode where the leds would blink fast.


I have some software development and some electronics experience so I'm happy to do some more digging.

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
