The optional "Altshell" plugin for Skeinforge may be used to generate gcode which will give an exterior shell that has none of the blemishes which might be caused by accelerated printing.
The "Altshell" plugin may be downloaded as the file altshell-plugin.zip from Thing 17855. The plugin is a single text file entitled altshell.py. Also included in the .zip file are replacement extrusion-NN.py files where NN is a the Skeinforge version number (e.g., 35). Installation directions, repeated below, are provided towards the top of the altshell.py file.
If you are on Mac or Linux, we've included an install.sh file written by Aaron Ciuffo which you can run by typing:
chmod u+x install.sh
./install.sh
Alternatively, you can follow these instructions to install manually:
First, locate the plugin directory for the version of Skeinforge you are using. This is a relatively deep directory tree. If the version of Skeinforge is NN (e.g, "35", "47", etc.) and the version of ReplicatorG is XXXX (e.g., "0034"), then the path to the directory will be
- Mac (RepG 33 and later): /Applications/ReplicatorG.app/Contents/Resources/skein_engines/skeinforge-NN/skeinforge_application/skeinforge_plugins/craft_plugins/
- Mac (RepG 29 and earlier): /Applications/replicatorg/skein_engines/skeinforge-NN/skeinforge_application/skeinforge_plugins/craft_plugins/
- Windows: C:\Program Files\ReplicatorG\replicator-XXXX\skein_engines\skeinforge-NN\skeinforge_application\skeinforge_plugins\craft_plugins\
- Linux: TBD
In that craft_plugins directory, place the altshell.py file.
Replace the extrusion.py file with the extrusion-NN.py file for your version of Skeinforge,
- Mac (RepG 33 and later): /Applications/ReplicatorG.app/Contents/Resources/skein_engines/skeinforge-NN/skeinforge_application/skeinforge_plugins/profile_plugins/extrusion.py
- Mac (RepG 29 and earlier): /Applications/replicatorg/skein_engines/skeinforge-NN/skeinforge_application/skeinforge_plugins/profile_plugins/extrusion.py
- Windows: C:\Program Files\ReplicatorG\replicator-XXXX\skein_engines\skeinforge-NN\skeinforge_application\skeinforge_plugins\profile_plugins\extrusion.py
- Linux: TBD
Be sure to change the name from extrusion-NN.py to extrusion.py. You may wish to save the original extrusion.py file before overwriting it with the replacement file.
If there is not an extrustion-NN.py file for your version of Skeinforge, then you can manually edit extrusion.py as per the directions found within the altshell.py file.
The Altshell plugin is then activated the same way you would activate any other Skeinforge plugin: edit the Skeinforge profile, select the Altshell plugin, and check the "Activate" checkbox. Then save the profile.
