Pointers on using Curaengine needed


Recommended Posts

Posted · Pointers on using Curaengine needed

Hi all,


I need some suggestions and help on using Curaengine.  


I want to use Curaengine for some backend and batch work.  I've got it built ok.  Poking around github, I've not found good documentation beyond what you can do from the command line.   Here are my questions:


1. I have my own front end.  I can call curaengine.exe from the command line but I suspect using it as a server is better since this is what cura does..  If so, where can I find information on calling curaengine running as a server?  Can I keep it running for each new file I want to slice?


2. I have 3MF files.  I see the command line wants STL.  Is there way to pass it 3MF?  If Cura does some pre-processing before sending the mesh to curaengine, I can do that too but an example or URL pointing to some code would be helpful (I have other applications using 3MF so I'm fine extracting the data).


3. I want to access the 2D polygons created in slicing for some special analysis.  I have no problem hacking the C++ curaengine code.  It would be great if someone out there already familiar with the code could point me to the right source files for a bit of hacking (it is just research 🙂 )

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
