Just thinking.

I built a CNC machine using Gecko drivers and CandCNC controller and it has been running flawlessly for many years. Using MACH3 and Vectric Vcarve software. I'm very happy with this system.

What do I need to do to add 3D printing capability to my exhisting hardware and electricals?

What do I need to change or add? And still keep my CNC capability.

Or do I need to build new hardware from scratch.

Did I mention I'm cheap, LOL
