Is it a filament printer? Does it use an arduino or other controller? I'm sure it wouldn't be THAT hard to reverse engineer, I don't have one so I couldn't say for sure. Worst case with a ABS/PLA and stepper motor printer I'm betting you could get some open source software on it. The Pegasus Touch is a different beast because it is a galvo laser 3d printer. Not very common, and I don't think there are any open source ones that are really widely used/known.
