There are a couple of inspirations for this thing: http://reprap.org/wiki/Plotting and the Unicorn http://www.thingiverse.com/thing:4185 and http://www.thingiverse.com/thing:790This is published early. Maybe someone else can use it. I am trying to get the workfow of the reprap site to work. Hint: also look at the discussions page - the Blender steps are not required anymore. Problem: When creating PNG files and doing the outline with inkscape in the end I am loosing the correct size in skeinforge.I also modified the python script for the unicorn to convert gerber files to move the built platform up and down instead of the servo. This works, but the outline for the file does not seem to be very efficient. Hence I try to go the reprap way.When creating a profile for skeinforge, I guess making use of the hop plugin is essential. Please leave comments if you have experience creating PCBs with the makerbot. I would like to get this working!I am currently experimenting with various skeinforge profiles. Results are quite promising. Here is a video: http://www.youtube.com/watch?v=X0ZCrDoRocEPlotter is a replacement for the plotter holder STL file. It has a wider inner diameter.
