Hi,
I am currently using grbl with 2 ULN2003 transistor arrays(per stepper).
The steppers are connected like this http://ssecganesh.blogspot.com/2008/05/driving-stepper-motor-using-uln2003.html
I tested my code also with a L293D H bridge and it works well. This could lower the price for a grbl stepper driver board.

Is this feature welcome in grbl? It would need a config option which decides whether to compile the stepper driver or the H bridge code.
Thank you
