CuraEngine command line: use Cura profiles instead of "-s" options?

[erri 2]

Hi,

i'm working with Cura (2.3.1) under linux. I have created a custom UM2 machine profile and some material/quality profiles.

Slicing with the Cura GUI is going well.

Now i want to atomate things, i.e. i want to use CuraEngine (from a Makefile) to slice my STL files into gcode.

To do this i would have to use many "-s" commandline options to specify the non-default slicer options (a look into cura.log reveals that it is calling CuraEngine with about 330 "-s" options, for example).

Now the question is:

Is it possible to use the Cura(-GUI) generated profiles (.cfg files stored in HOME/.local/share/cura) instead of listing them one by one on the CuraEngine command line? It seems that there is no commandline option to specify Cura profiles :-(

Or is there some other way like generating a list of "-s" options from the Cura profiles?

The logs output them when a slice starts. You can just copy them from there.

Of course i can copy it from cura.log... But i am looking for a more integrated/elegant way, something that is more 'single source'.

Problem is, for example, if i change the machine/profile in cura, i have to remember all places (scripts, Makefiles) where this profile is used (hardcoded settings) and have to update them by hand... This is duplicated and error-prone work.

I would like to avoid such hardcoded settings and instead reference the cura profiles at theese places.

We don't have that. The setting architecture is quite complex. Porting it to the engine would only increase the odds of it going wrong (as we'd be re-implementing a bunch of code in another language). As we don't even use it, i don't think it's likely that we're going to spend time on this. We have a lot more stuff that has higher priority.

I’ve the same problem.

Any news about how is possible to use the Cura generated profiles (.cfg files) instead of listing them one by one on the CuraEngine command line with -s option?

[nallath 1,124]

Nope. We haven't put any time into this. This might change in the future, but I don't expect this to happen in the very near future. The next release (2.7) won't have any changes regarding this.

Hi,

i have written a python program cura-engine-wrapper.py that reads the slicing parameters from Cura machine and quality/material profiles and calls CuraEngine with them to slice a model (stl file).

You can overwrite specific profile parameters on the command line and there are some additional use cases like listing available Cura containers/profiles or dumping the parameters of a given profile.

You can find it here: http://github.com/ErwinRieger/ddprint/tree/master/scripts.

Protip; use the CuraContainerRegistry. It does a bit more magic. If you ask the value from a stack that is returned there, it should also handle the resolve. Should be a simple as switching out the ContainerRegistry with the CuraContainerRegistry.

Also; Very nice work!

@nallath: Thanks for the tip, i will look into this.

Updated the script, replaced ContainerRegistry with CuraContainerRegistry.

@@Nallath: The value for *infill_overlap* is not resolved/evaluated (neither by using ContainerRegistry nor by using CuraContainerRegistry):

infill_overlap = =10 if infill_sparse_density < 95 and infill_pattern != 'concentric' else 0

I think this code has to be evaluated somehow before it gets passed over to curaEnginge?

Any hints?
