It would be nice if it were possible to execute the custom End G-code
when a print is aborted.  I end up doing all the steps manually
anyway, and it would add a bit of convenience.

I passed the request on to upstream.

Hi Joe.

The developers have responded in
<URL: https://github.com/prusa3d/Slic3r/issues/538 >, but their answer made
it clear to me that I do not really understand the issue enough to be a
middle man in the process.  Could you perhaps join the discussion there and
provide more information to the delopers to explain what exactly you are
asking for?
