Programmatically send a CAD file to Cura via JSON push

Posted · Programmatically send a CAD file to Cura via JSON push

Hi All, 


Is there a way (such as a plugin) to send a CAD file to CURA and open it automatically?
I can provide a JSON using Post, and it will contain a URL to the CAD file

"modelUrl": "https://[mylinktothecadfile]",


Thanks, All!

    Hey @Sven_Hinrichs,


    Welcome to the Ultimaker Community 🎉
    This looks like something that the ThingiBrowser does. 
    You can read more about it here: https://github.com/ChrisTerBeke/CuraThingiBrowserPlugin

    It get's more trickier if you try to load a file format that is not supported 
    This is a list of supported file types https://support.makerbot.com/s/article/1667411286871

    Can you help me understand, what problem are you trying to solve?

    Hi Mari, 


    Apologies, I didn't see your reply!

    Essentially, I'm trying to automate a process where designs are stored centrally and I can "order" them from a central system. I want to avoid having to go into CURA and opening cad files individually (pull), but I'd rather have them pushed into CURA. 

    I have the following components:

    • A library of CAD designs, hosted on AWS
      • My S3 bucket is mounted as a local drive (via rclone)
      • I have access control, so I can pass a URL from where the files can be downloaded
    • Fusion360, 
      • This exports the CAD file directly to the S3 bucket
      • Today, I'm exporting it to the mounted drive
      • Once this all works, I'll get the JSON exporter plug-in to save files automatrically
    • A slicer, such as CURA
    • A tool to post JSONs; I use make.com
      • I can easily query my S3 bucket by file name and retrieve the CAD file URL
      • I can then pass that URL to {hopefully} CURA
      • The CAD file should then automatically load

    Hope this makes sense?

    You can have Cura slice from the command line.  Does that help?  It's not trivial as there are many configuration files (machine config, profile, overrides, material config, per-nozzle config) but many people use this technique to automate slicing.


    google "cura engine command line" and read both the github and forum articles.

      • 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.
