It seems, the shift registers need some initialization code to configure MS1-MS3 of the drivers? Or are they pulled to GND automatically?
Why not use a RAMPS shield with GRBL?

... could be, your drivers draw more current from the +5V of the Arduino, than the voltage regulator can deliver -- so the +5V of the Arduino breaks down and the program stops.
If it's working fine without connecting, then the +5V for the drivers are sourced elsewere ... so better let it "open" ...
