I had problems with a file generated by Slic3r, so I decided to view the g-code file, and thought I'd try out S3d's previewer. The program promptly crashed. I deleted everything out, so all that was left was comments at the bottom, and it still crashed.
Tried a file generated by S3d, and that crashed S3d crashed too.
Has anybody gotten this feature to work in the current version? Am I missing something that is not obvious, like "File->Preview G-Code File..." does not let you actually open and view a g-code file?
