Download and install Psyco Link to Psyco Download this speeds up the running of skeinforge.(again you can accept the default install folders)

Debian testing contains a package sfact and for ubuntu there is now also a ppa available (maverick natty oneiric precise):



The default settings in craft, analyze, fill, raft etc are OK for a first attempt at printing, but you might find that changing these to settings on the Polymers page of the wiki give better results. Oh, and to get Skeinforge to process the stl file click the “Skeinforge button”, browse to your STL file and open it. A gcode file will be created in the same folder as the STL file. copy stl file to SD card and off you go  :-)

I would advise reading the “operation manual” that can be downloaded from the V3.0 section of the BfB website Operation Manual I hope this helps, good luck.
