looking for (paid?) help setting up a cura engine or command line command

[philippeholthuizen 0]

Hi All!

I want to use a 3mf file  with 1 merged object inside to load, and then scale by a certain percentage in xyz, center, slice and save as gcode.
This has to be repeated 20 times, generating 20 different sizes of the original merged object.

I think the 3mf file should have all the printer, profile and material settings. But those can also be loaded separate if needed (though I'm not sure where to look).

Does any of you know how to set this up? Doing it by hand takes a long time, and I have to do this for several objects, and again if any of those objects needs an update.

THANKS!

I'm pretty sure CuraEngine can't load 3mf files natively. Cura sends the models in STL format and while it sends all the parameters as text over the WebSocket connection CuraEngine, you can just pass CuraEngine a JSON file containing the settings. I have no idea if CuraEngine handles transforms like scaling or if Cura handles that.

 

I think the solution is the same as what it is to many problems which need automation: 🐍Python.

You could easily create a script which would scale a model to a bunch of different sizes and save them as separate STL files, then feed them to CuraEngine using the same settings JSON file.
