I would normally use 2 drivers with one set of pins.

Normally you would use two separate drivers. As a more advanced topic you might want to home the motors individually to auto-square the gantry.
There is a kinematics module that maps multiple "joints" to a single "axis". Have a look in the sample configurations for the one that mentions "gantry" and "stepper" and look how that is configured.
