Hi,

I am planning to design my first cnc that is mainly for PCB and aluminium. The dimension of is about 700mm x 700mm x 700mm. The design is to have the spindle to move in x and y axis. The bed will be moving in the z axis. Would be glad if anyone willing to give suggestions.

The current specifications are:

1. 8080 aluminium profiles for the frame (with angle brackets ?)
2. 1605 ballscew bearings (2 x-axis, 2 y-axis and 2 z axis)
3. Nema 23 stepper motor

Attached are the design from various perspectives.
