You can print on angled surfaces and cylindrical surfaces. I'm actually having trouble wrapping my mind around 6 axes... I feel like a stick figure trying to envision what it's like to live in the 3D world. Or should I say an inkjet trying to imagine life as a reprap... hehe

Would be sweet to get a few more axes on makexyz...
