Raspberry Pi – Stepper Motor Control

I’m new to hobby robotics. I want to build a cartesian robot for a pick and Place application. Nothing is engraved in stone on this project, but I envision five stepper motors and two servos, ultimately being controlled by Python running on a Raspberry Pi 3 model B. There will a limited number of well defined pick and place points. Some parts have been bought and a lot of the 3D printing has been completed. No programming has been done yet.

My question is “Would it make good sense to use a GRBL CNC control board to interface with, at least, the X,Y,&Z steppers or would programming be more straight forward using stepper motor hats?”

I look forward to any advice that may come.
