Exactly, when a single Arduino can use GRBL or similar and run a CNC machine or laser cutter or even a 3D printer then it seems very odd that getting an Arduino to control two stepper motors is ...

The machine uses a ‘grbl’ controller, which has an Arduino-based circuit that includes multiple outputs, including a powerful 24V pwm signal that is generally used to drive a 60-80W spindle motor..
