Hi guys, I am pretty new to the whole world of CNC. Could someone walk me through the basics and tutorial on how to build one. I do not have unlimited funds and I don't mind tinkering. I am looking for an average size CNC. I want it to be as sturdy as possible and as precise as possible. I will be doing mostly aluminum/plastic parts. 1- What would be the best frame to do what I want? Are kits worth buying? 2- Best motors ? 3- Controller board. Is an arduino fine? 4- What should I avoid ? 5- I live in Canada where do you guys buy the parts or do you get them made for you?
