Introduction: (reference)super Simple CNC

About: I live in Toronto, Canada and I build almost anything computer related, Anything from robots to computer interaction devices. My favorite programming language is C+ and micro controller is avr with the Arduin…

Hear are my designs for a CNC. My goal is to make a cnc anyone can build with no special tools except a screwdriver. Please comment on what you think even if its criticism. 
Some things i would like to improve are

*The z axis: i feel like it could be similar 

*the x axis carriage could be simpler without special bearings
