Caulk Tube Based 3D Printer (CNC attachment)

[scorch]

I'm really impressed with this idea, scorch.

Thanks.
It is pretty straight forward but the big sticking point for most people is that you need to start with a CNC milling machine that has the capability of running an extra motor for the extruder.

I swap my extra motor between my rotary table and extruder as needed. I would like to come up with more uses for the extra motor.
