Thanks for the tips!
I'm not at that level yet, but this knowledge will come in handy. I'm just trying to get a feel for the variable needs each program/shape demands. I created some standard size blocks and circles/rings files for calibration and trial and error test runs. It's amazing how differently a 12.70cm cube prints when you start changing the variables from print to print. I'm using Simplify for slicing, and am intrigued by the options you are given to dial in a print/build.
