Re: Stepper Driver to CIM

The DRV8818 stepper drivers from TI used on the grbl sheild are for stepper motors and are not compatible with brushed motors. Stepper motors are electrically and fuctionaly different from brushed motors (like a CIM). Closed loop speed control with talons and encoders are the way to go.
