UltiController Backlight Issue - Flickering, then Dead


Recommended Posts

Posted · UltiController Backlight Issue - Flickering, then Dead

Hi,

we've just built the UltiMaker. However, after a while (about 1 hour), the display's backlight started flickering, then went dead. It seems that there's an error on the LCD, any suggestions what to do?

Thanks,

Felicitus

    Clarification of "Flickering": The backlight turns off and on again in short intervals (>300ms) and sometimes stays off or on - this happens during the operation. This might be a cold soldering joint.

    If it happens after an hour, it could also be that the 12V regulator is very slowly overheating.

    The Arduino uses 12V to make the 5V for the UltiController. You could try plugging in an USB cable to a computer, just to test. If the problem is gone then, then it's the 12V regulator.

    No, it flickers also when USB is connected.

    Then the most likely cause becomes a bad connection or bad cable.

    I believe it is a manufacturing fault. In order to proove this: Which of the pins is responsible for the VCC of the backlight? Are there schematics available so I can debug prior claiming warranty?

    Yes, schematics are available.

    This is the PCB of the Ultimaker itself:

    You will have a 1.5.6, but the differences are not that great, the main difference is a jumper "ARDPWR" between the 12V line and the Vin of the Arduino.

    The UltiController is the same as this:

    You should contact support if you suspect faulty hardware. (support is always quite busy, so the more info you can give them, the better and quicker you get a response)

    The issue has gone away - so I finally have no idea what could have caused it. Probably a bad cable or something.

      • 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.
