I want to create a CNC plasma.
I am looking at running GRBL on an Uno and had original thought to run the GRBL shield but am concerned that it cannot run larger stepper motors. So I started to look at commercial stepping controllers.
Could I run 3x CW230's in place of the GRBLShield?
would RESET-, CW-, CP- ground on the arduino,
CW+ hookup to Directon axis pin
CP+ hookup to the Step axis pin
