UM 3 extended not cooling the print core AA


Recommended Posts

Posted (edited) · UM 3 extended not cooling the print core AA

I did a 7 hour print successfully. After that I started a new print immediately. First everything was ok, but after a while nozzle didn't extrude material properly. I stopped the printing. After that print core aa didn't cool down (it stayed 175c and just said "waiting"). So i booted the printer. I unloaded material 1(pla) and loaded the same material back. In loading The material came out from the nozzle end (maybe little bit thin). After confirming the loading of the material printer started to cool down the print core aa. It was again stuck for maybe 15minutes and didn't cool down (said "waiting" in the printer). I booted the printer again and waited for the cores to cool down to 40c. After that I tried to start printing and cura was stuck in preparing phase for a half hour and it didn't start printing. The temperature of the core aa was around 210c all the time. II had not other option the to boot the printer again. Is there a problem with the cooling or why is it just stuck in preparing phase?

    It sounds like your front fan may not be running; if strings of filament have gotten caught in the fan blades, the fan won't run. If it's not running, the print won't start, but it also won't be able to finish cooling down the print core after you try to abort it.

    Power of the printer and use tweezers to try to remove any visible strings of filament around the fan. When the fan is clear of debris strings it should run normally again.

    It would help if you could send us the logs when this happens.

    This can be done using the menu steps:

    System -> Maintenance -> Diagnostics -> Dump logs to USB.

      • 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.
