Thank you for helping!
I am using The Replicator Firware Version 7.5 on my 3D printer. In doing so it only prints .x3g files. So far the only program I found to exporter .x3g is Replicatorg.
The bad thing about Replicatorg is I do not like the default Gcode generator (Skeinforge), it does have a slic3r option but the slic3r option is really generic and an older version so it is missing some settings I would like to use. I would rather use slic3r alone and export the gcode into Replicatorg to generate a .x3g file.
I have tried this a few times and each time my machine begins extruding a lot of material and does not move it just sits in one place. I figure its because the gcode it generates is not compatible with replicatorg.
I wanted to see if anyone had some suggestions.
