Also if you want to save some time, you could look into the X-Carve or shapeoko 3. Not sure if ether is available over seas, and both cost much more, but I feel would be a bit faster. I personal don't know how much I would trust a CNC made of mostly 3D printed parts, but I guess it works for some as an entry level CNC. Great video btw
