UM3 Extended "Bricked"


Recommended Posts

Posted · UM3 Extended "Bricked"

Hi Everyone,


after years of lurking, i have been struck with..."semi tragedy".


I have an Ultimaker 3 Extended ( firmware at this point was 5.2 something i think ), and that lovely machine has worked almost perfectly for all those years. With almost i mean: a year or so ago, i noticed that i could not switch to cabled connection, no light would show on the RJ45 connector, and when i tried to run the Wifi wizard, the screen would go blank for 2-3 seconds and the main menu would show. Did not bother me all that much, because i could send print jobs wirelessly via cura with no problems. Last weekend, i decided to make a thorough maintenance run, realign axles, tighten belt, calibrate everything, and decided to do a factory reset clean that too. Well after the factory reset, the Printer would not boot into the menu. It turns on, lights beep, but the LED strips would not turn on and the menu not boot. Shocked, i started looking into the forums, and embarked into a 16 hours odyssey of "trying everything". 

Long Story short ( or: this is where i am now ) :


- Wifi Board removed
- NFC Cable removed

- Tried docents of firmware recoveries (uSD), AFAIK the only one who breathed life back into the machine is 3.7.7.

- Every attempt to update from there "kills" the machine again

- Olimex cable is ordered, waiting on it.

- Still can´t get connection via Wired connection.


i assume i will have to go through the procedure given by the moderator gr5 ?

Maybe someone has some hint or help to make me understand what could be broken ?


Thanks for any help

      • 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 5.3.0-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.
