The Electronics: Sanguinololu with Polulo stepper drivers

The Electronics: a Sanguinololu controller and 4 Pololu Stepper drivers (one for each axis X,Y&Z and one for the Extruder Stepper motor). The Polulo drivers shown here are Ice Blue Stepsticks.

Here the Pololus are mounted on the Sanguinololu. Let's hope we don't blow these up when powering up the Sanguinololu.

Next step: wiring - extend and route all wires to the Sanguinololu board.

(and finding out where the mechanical endstops go for each axis.

This is the Sanguinololu wiring schema:

Mounted an extra Fan needed for printing PLA, not needed for printing ABS.

Pololu steppers + belts installed

Added the Pololu stepper motors and the belts.
(Pololu Type: NEMA17 Stepper motors 1.8 degrees step / 4.8 kg/cm)

The Extruder has to come of again to attach both the stepper motor and the hotend.
