Can't get firmware to upgrade after install of UM2 extrusion kit

Posted · Can't get firmware to upgrade after install of UM2 extrusion kit

I have a seven year old Ultimaker 2. I just installed the UM2 extrusion upgrade. All went well. Only thing off was that original UM2 did not have ferric core around the motor wires. Tried to use Cura to upgrade the firmware and there was not 'Ultimaker 2' choice. Tried the UM2 Connect version and unit does not turn on normally. Front display stays black. Don't know what to try next. Any suggestions appreciated.

    After the extrusion upgrade, you have an UM2+, so the FW for UM2+ should work. I think it is also important that you add your printer also as UM2+ to Cura.


    The UM2+ Connect is completely different and I am wondering that you were able to install the FW of it. The UM2 has an Arduino board and the UM2+ Connect is using Linux. 


    So I would try to add a new printer UM2+ to Cura (use Extended if you have an Extended) and then try again to upgrade the firmware.

    Thank you Smithy,

    Very prompt and helpful ideas. I had success today when I spoke with Tony Harris at fbrc8 support. He diagnosed a loose connection of a flat cable from the front display. I opened it back up and voila, one of the cables had come loose. Got that seated and the um2 works well now. A big relief. Thanks again. John

      • 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.
