Hi,

I need to add new material to the UM S5 - as I have understood this can be done via this UM API. Can anyone show me in more detail how this can be done.

My first attempt was to create a XML file as below. (Observe, I need to add this to the UM S5, I know how to use Cura - will not serve my needs)

<?xml version='1.0' encoding='cp1252'?>

<fdmmaterial xmlns="http://www.ultimaker.com/material">

  <metadata>

    <name>

      <brand>Colorfabb</brand>

      <material>PLA</material>

      <color>Copper</color>

      <label>Colorfabb Copper</label>

    </name>

    <version>1</version>

    <GUID>eaf3d290-843f-4955-8fbd-5431073071e7</GUID>

    <description />

    <adhesion_info />

    <color_code>#B87333</color_code>

  </metadata>

  <properties>

    <diameter>2.85</diameter>

    <density>3.90</density>

  </properties>

  <settings>

    <setting key="print temperature">210.0</setting>

    <setting key="retraction speed">40.0</setting>

    <setting key="retraction amount">1.0</setting>

    <setting key="standby temperature">175</setting>

    <setting key="heated bed temperature">60.0</setting>

  </settings>

</fdmmaterial>

 

When I try to upload this file I get :

{ "message": "Authorization required." }

 

What should I do differently?

Best regards,

Hokki

    You have to authenticate yourself for most write requests.

     

    Check out these APIs:

    This generates new id/key combination that has to be used as username/password in the digest authentication on certain APIs.

    ultimaker/ultimaker is not a valid id/key combination fo the apis, it is for SSH login.

    You have to carefully read the description of the authentication api I mentioned above. 

    First of all you have to make an auth request with your parameters like user, application. Then you have to confirm this request on the printer display it self. 

     

    Only then can you use the id/key combination to authenticate your other API calls.

    OK, sorry my mistake. So I did like this - safari/hakanfa, confirmed in UM S5. So far so good. But when trying the "post material" I still get the Authorization required message. Should I put the user info in the XML file somehow?

     

    Thank you very much for swift replies!

    When you did the auth request, you got a json response with id and key.

    {
      "id": "string",
      "key": "string"
    }

    This is your username (id) and password (key).

    Then you have to use both parameters for the http digest authentication. How you have to use the digest authentication depends on your scripting language. 

     

    For Python (untested, just out of my head):

    from requests.auth import HTTPDigestAuth
    url = 'http://<printer-ip>/api/v1/materials'
    requests.get(url, auth=HTTPDigestAuth('user', 'pass'))

    And if you don't use any scripting language, but just the browser, then you need to enter id/key in the popup window which is shown after calling the api.

     

    If no popup is shown, then close your browser and open it again.

    Ok, now I understand. - thank you, will try it out as soon as I come home.


    I will just call the post material API via the browser. The purpose of doing this is that I use the UM material station - all works fine with NFC tagged filaments but I use a lot of 3rd party filaments like Colorfabb. If you have many “generic pla:s” the Cura/UM does not know which to choose. One update proposal to Cura would be ability to choose from what bay to load the filament - not only the type of filament.

    I guess this feature will come in future firmware/Cura updates.

    You can also import the material into cura, if it is connected to your printer then upon restarting cura it will sync materials with the printer.

      • 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.
