Convert my CNC to 3D Printer with 3D printer kits

I have a DIY CNC and I want to convert it to a 3D printer. Recently, I bought a PiBot Electronics Kits 2.0D . It is convenient to install ,support dual extruders and automatic adjustment function of Z axis. The CNC framework is able to provide more space for 3D printer. Another cool thing is, the PiBot Controller Board Rev2.0 in the kit supports 3D printer and CNC 2 in 1. If you have a DIY CNC and want to convert it ,maybe you can try it.
