3D Printer Babbling
Reprap-based 3D printers speak a dialect of gcode, which CNC machines have been using for decades. It's a human-parseable series of control instructions and locations - point to point in 3space, extruding filament along the way. The more complicated the object being printed, the bigger the file. The rings were a few hundred kilobytes.
Tonight, I'm trying a 30mb file generated off a MakeHuman model. I don't expect it to work, per se: I do hope the failure is informative. n.n
