Controlling 5 axis CNC using arduino uno
10/16/2017 · I did some research online and watched a few tutorials and I believe I understand how to control 3 steppers using grbl. A friend is sending me an arduino uno with a CNC shield (not grbl but grbl compatiple) and 4 stepper controllers. The CNC shield has 4 spots for controllers labeled X, Y, Z, A. So I assume with that shield I can control 4 axis.
