Ok... so what will we build then?

Reprap?

Lets consider a few thing:

1 availability of parts.
2 ease of construction.

with that in mind lets start with the electronics.

The most popular boards at the moment is the RAMPS,Sanguinololu and Generation_7_Electronics.

My first choice was the RAMPS and the the availability problem kick in. same was the case with Sanguinololu, none available in South Africa.

I decided to go with the Gen7 ver 1.5 board found all the detail needed the edge the board at home.
next I will need to get all the components required to assemble the board,
Gen7 Board-AVR 1.5  for all the detail needed to build the board.

  The Gen 7 v 1.5 has on board USB so no need for the add on USB interface.

with this board I will use #
Pololu DRV8825 Stepper Motor Driver Carrier, High Current 2.2A
4 NEMA 23 1.0 NM Stepper motors and 1 0.5NM stepper for the extruder.

next step get all the parts.
