!cnc-shield V3
Arduino CNC shield V3 has this type of axis clone feature which does not require any firmware changes. It’s an easy way to clone any axis to the fourth stepper motor header in Red color( on V3 shield in pic).

Well that’s totally dependent on the PCB design. The V3 CNC shield simply connects the Step and Dir pins of the two stepper motors with jumpers, this is very simple and saves some pins.

However this type of Axis cloning can’t provide some functions like Self squaring gantry which requires the control of independent motors. Just recently they have added this feature in Arduino Grbl for one axis.

So it’s upto to your requirements,
You should be fine with the Arduino Grbl, since it’s very simple and easy to setup.
But if you need some cool features like Wifi, SD card, SPI drivers, More axes…….. You choice is obviously the

Closing.

This is not a firmware issue.
