Gcode IOError: [Errno 2] No such file or directory

[Duality4Y]

I cloned the repo, and installed.
I get the error that pronterface can't find the exported gcode file.
it seems that the file is renamed but not loaded under it's new name.
loading by hand works.

full output:

Hi @Duality4Y,

Thanks for reporting this, and good OP by the way. This seems pretty easy to fix but...

@kliment, is there a reason why printrun expects a sliced file with the suffix "_export"? Slic3r does not add that by default, does Skeinforge?

Regards,
Rock

Skeinforge does.

Dear @Duality4Y,

Could you try adding -o $o to your slicing command (Settings > Options > External Commands > Slice Command). Mine is slic3r $s -o $o and it works as expected.

By the way, the README.md says:

See the Slic3r readme for more details on integration.

But I can't find where exactly this integration is explained, could this section be missing by any chance?

Regards,
Rock

[Duality4Y]

yes that works!
pretty cool,
maybe it could be mentioned in the readme to note that you have to use -o $o to generate the right output file for slic3r.

though i wonder if it would be easier to by default just use thing.stl -> thing.gcode and load it that way.

Skeinforge does, yes, and it's not configurable there.

To make it work, I had to open the Slicing settings, then switch to Expert Mode (File>Preferences Mode:Expert) then OK, then kill Slic3r, then re-open the Slicing settings to start in Expert mode, then Output options / Output filename format: [input_filename_base]_export.gcode - i.e. I had to add the "_export" part.

It is sort of amazing that I had the patience to dig deep enough to figure that out.
