using L293D h-bridge with current sensing for stepper chopper circuit

a_g123:
thanks much for the replies the steppers i'm trying to control are NEMA17 motors commonly found on the cheaper 3d printers

And how many of those 3D printers are using L298 drivers for their stepper motors?

Think about it ... those guys will wish to save every penny in materials cost but they don't use L298 drivers. That must tell you something.
