First Proper CNC Router

If it were me I'd run the enable, pulse and dir. signals as twisted pairs - common the -ve ends up at the Arduino. This approach gives much cleaner waveforms and better resistance to interference.

Would something like a CAT 6 cable be a good idea?

CAT6, CAT5 whatever you have lying about. Try one length of cable per driver with all the screens grounded at the Arduino end as well. If you can keep the cable runs for driver input signals and high current motor outputs separate that helps too.
