2 wire vs 4 wire Stepper motor driver?

Projects General Guidance
1

HI,

I am building a 3 axis cnc mill, and have a questions about the type of driver to use. I have 4 nema 17 motors, and purchased four 4 wire control h-bridge drivers(L298n). Most of what I am seeing in the cnc building community are the use of 2 wire drivers (step, dir) such as the Sparkfun easy driver or the Pololu a4988 driver, and I am wondering if this is the better way to go as opposed the the 4 wire control? Also, in my searches, I am not finding the Arduino g-code interpreter/stepper controller that would control a 4 wire stepper driver, and am wondering what is out there to do so? I know grbl was able to in past revisions, but have dropped support for doing so in the latest releases. Any help would be appreciated,

Thanks,
Jake

you can check with Sparkfun tech support, but I'm pretty sure you just ignore the middle wire to use a 4 wire (per winding) as a 2 wire.
I have the big easy, and it is easy.
