Ultimaker material UNKNOWN

Recommended Posts

Posted (edited) · Ultimaker material UNKNOWN

Hi, I've an Ultimaker 3 and have been using it since it came out.

The NFC spool holder never worked but it doesn't bother me much so I never try to investigate.

Last week I went through the menu on my Ultimaker (for fun) and noticed that in the NFC hardware Test in the Diagnostic menu says

NFC hardware not detected

I disassembled the spool holder and noticed that the cable is detached, I reattached the cable and check Diagnostic again, and now it says

NFC Hardware detected

I was super happy and then proceed to load my material, but it is still not detecting my Ultimaker filaments. 


I go to the NFC reader test and this is what it says

ID: 0444783acb5281

ID: 04f0ad5ad26480


My spool 1 is Ultimaker Silver PLA

My spool 2 is Ultimaker Red PLA


The materials are put with the NFC facing each other at the center. 


It would be nice if someone can point me in the direction to get it working.

    as your sensor now works properly (the serial numbers of the NFC tags are recognized), there are three possible reasons why your material is not recognized:

    Either the NFC tags are defective (which can happen), or the serial numbers are unknown to your printer, which indicates that you probably are not running the latest firmware or the serial numbers are missing in the database (which also can happen).

    Possibly it helps to just unload the materials (including removal of the spools) and reload them again.

    I don't know if a reset of the printer or Cura Connect could help (so I don't recommend so far).

    I have unloaded my spool 1 (Ultimaker silver PLA) and spool 2 (Ultimaker Red PLA).

    And then loaded the Ultimaker silver PLA into spool 2 (NFC side facing away from the back of the printer), it says 

    Material not detected. Please check spool or select from list of materials.

    I open a new box of sealed Ultimaker pearl white PLA on spool 1 and load the material, it also says

    Material not detected. Please check spool or select from list of materials.

    I waited about 1 minutes to see if it will eventually detect the material before I move on for both of the spool.


    I then go to maintenance menu and do a NFC spool holder test and it says

    NFC hardware detected


    The printer is running firmware version


    Thank you very much for your help

    That's strange.


    Normally when prompted to insert the spool, the "material not detected" message dissapears after a few seconds, reporting the found material.

    As you say, NFC tags face each other, that's ok (material 2 placed near the printer, running clockwise, material 1 placed on the outside, running counter clockwise.

    After you have run the NFC hardware test and the serial numbers of the NFC tags are recognized, you could try another thing:

    In the "Material/Print Core"-Menu, sub menu "Material (1or2)", there is a point "select material", which also activates the NFC recognition of a loaded spool. It should recognize the NFC tag after a couple of seconds.

    @maht, is there something else that could be done?

    I just bought a new spool of pearl white PLA Ultimaker material and loaded it in SPOOL2 and now it can register automatically!
    It's so strange, it's as if all of my other materials(Red, Blue, Black, White, Translucent...) has NFC serial issues or something.


    I will buy more new material and see if new materials can be registered correctly.

    That's good news!

    So at least your NFC reader and the material database proof working 🙂.

    Could your other spools have been exposed to a strong magnetic field or so, which could have damaged the data on the NFC tags? One or two defective NFC tags may happen, but you've counted 5+ and this would be a very strange co-incidence (would be worth buying a lottery ticket 😉).

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!

      • 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 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.
