AA0.4 is recognized as AA0.6


Recommended Posts

Posted · AA0.4 is recognized as AA0.6

I have replaced a worn-out AA0.4 core on my UMS5 with a new one. However the S5 recognizes as "AA0.6", which doesn't even seem to exist (I know only of a AA0.8 and a CC0.6). I switched the printer off completely and rebooted it, and the issue remains. I also removed the AA0.4 and inserted it again using the Change routine, to no avail. Now I am manually overriding the AA0.6 directive on every print, and that works more-or-less, but it is a terrible nuisance. What can I do?  Thanks for any advice!

    To change core name, instructions are here:



    Note that original 3dsolex cores were called "Hardcore" in their eeprom but hitting "ignore" all the time got to be too much at some point especially with "cura connect" so now they are also "AA 0.4".


    Note that I sell 3rd party cores that work with UM3/S3/S5 at thegr5store.com.

    Thank you for your advice. I may have to reprogram the core via SSH then. However, I find it extremely troubling that a $150 factory-sealed original Ultimaker core is wrongly programmed to a nozzle size that doesn't even exist. Is this a common occurrence? If so, it's quite frightening. Alternatively, I am worried that the core may be OK and something inside the printer is messed up - which may potentially be worse...

    I would reach out to your reseller about exchanging that Print Core.

    It's not a common occurrence, and this should not be a problem with the printer, just the Print Core. Most likely when Print Cores are programmed there are probably 2 settings--pick AA, BB, or CC, and pick a size. Evidently someone hit the wrong size on the size option.

    If there's an issue with the Printhead PCB board, it wouldn't read the Print Core at all, it wouldn't give it a wrong size. If the printhead PCB was the issue, it would give a message that said the Print Core wasn't recognized.

      • 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.
