About this 3D model

I wanted to build a cnc machine and decided to buy a Proxxon MF 70, and add my own motors and controllers. this is the machine without the motors: http://www.proxxon.com/eng/html/27110.php I had NEMA23 steppers laying in my drawer for a while and decided to put those on the machine. Added end-stops on all axes. My stepper controller is a 3 axis TB6560 with 300watts PS. Interface is an Arduino Uno with GRBL. Software : Universal g-code sender For cam software i use : HeeksCnC The machine has a lot of backlash on the x and y axis, you can get rid of them by putting self-lock nuts on the axis @ the end ( oposite side of motor. ) on the inside of the end plate. P.S. one nut is normal M5 (y-axis) other one is left turning M5(x-axis) .
