A4983 on a breadboard

The Smoothie project will use the Allegro A4983 chip to drive the stepper motors.
It's a very nice chip, it has 1/16 microstepping, can drive up to 2A, and has the simple step/direction interface.
Most common way to use it is via the Pololu Driver Carrier, but in the case of Smoothie, we want all of the 4 drivers directly on the PCB, so that they can share the heatsink/fan, and also share some components. (read more…)

That will allow direct control of the current settings from the firmware / via serial commands, and automatic benchmarking of the current settings. (read more…)
