WHAAA? The default settings of the machine would be the firmware, and the last time I checked, firmware doesnt load stl's, slice it and then create gcode. Just creates variables like max printing area etc.
You have to actually slice it and use a controller like pronterface to read the sliced file and print.
So..... you changed your slicer settings for some machines to print with support and some not? Sounds like an agenda to me. Your guys' explanations of how this test was conducted, never added up.
