Re: stepper driver

Hi, this is a simple circuit that immediatly comes to mind.

I am also building one of these so I will prototype it this weekend.
For a four axis machine, it would need one hex inverter, and two quad
and gates. I'm sure there is probably an even simpler way to do this.
Anyone know of a better solution?
