linux: how to send STL to running Cura from command line?

Recommended Posts

Running Cura (3.3.1) on an Xubuntu 16.04. I didn't go through the hazzle to build my own Cura but am simply using the provided AppImage


I would like a way to send produced STL files to an already running instance, simply adding to the build plate. STL's are generated by some scripts, so I would prefer to avoid manually loading them from withing Cura.


It seems to work seamlessly on a Mac, so it should be doable on Linux with well.


I try something like:  

cura /home/mogul/stl-dump/benchy.stl

which starts a new Cura, so if I would like to add another model to the same print I had hoped simply to repeat like

cura /home/mogul/stl-dump/marvin.stl

but the later unfortunately starts a new instance of Cura rather than applying Marvin to the same plate as Benchy 


What am I missing? How can it be done?

I think the commandline argument you are looking for is —single-instance. That should connect to an already running instance and hand over the file to that.

--single-instance do indeed get me the same Cura instance. But unfortunately when I call it second time, it replaces the part, not simply adding to the build plate.

I want to print a Marwin and a Benchy at the same time.

I couldn't find an option for that. Can it be done?

Doesn’t “./cura marvin.stl benchy.stl” work?


It does. It isn't exactly the same workflow as I have on the mac where I am able to throw parts over one by one as they get made by the CAD tool chain.

Now I will have to build all the STL files and then kick them to Cura in one go. I think I can work my way around it.


I just find it a bit strange the same program on two different platforms behave differently here, but well, not a biggie, the

--single-instance helped a lot.

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
