I ran Test Part A through Slic3r to generate some representative G-Codes just to see if it would process without major errors. Of course the actual processing will require setting parameters that aren't available yet. Then I loaded the resulting data into Pronterface-Mac to see the actual tool paths and get some estimates of the expected run time and required material volume. The reported numbers, 15 hours run time, just provide a relative estimate and I expect they are very pessimistic. There will definitely be a lot of 'fine-tuning' necessary.
