CNC drill/mill machine V2 – Electronics Part – Update

I’m going to drive the steppers with a chopper steering. I’m going to build my design around the L297 and L298 ic’s. The parts I’m going to recycle from the driverpcb’s I got from Rik (See the picture bellow). The reason I don’t use these pcb’s like this is because if I connect a stepper motor then it already starts to turn without a signal. And the input signals are not universal.
