CNC building decision

[Dinius]

Hi, Im planning to build a "mid" size CNC machine for wood and aluminum milling.

I have attached some concept designs which I´ll be please to hear what do you think about them and which one you thing is the one I should develop.

Material Im planning to use:

- Aluminium profile Heavy 90x45 & Heavy 45x45
- Aluminium 270x19 Bed
- Hiwin 20 rails, whit HWG20 & HGH20 carriage
- CFU Ballscrew 20-05 (very similar to Hiwin, 0,02 difference). (Also its Flange housing and BK, FK, FF & BF bearing block)
- 12mm & 6mm laser cut steel plates
- Nanotec Nema 34 stepper motor
- Gecko G540 Driver

And thats about it

For the spindle Im still thinking about it, don't have it clear... And Im still missing the Power supply

Well, I know Im missing info, so please ask...
