4. It seems like I am unable to escape the need for a ST330. Just to clarify, if I use the arduino, the connection would be as follows:
arduino->stepper-shield(like
this)->ST330-driver(or alike)->stepper motors
I did see
this shield, does it negate the need for the stepper-driver-board?
I also read that this "
stepper motor carrier driver" is required when using the reactive substance shield and the arduino...getting a bit confused on what is necessary after I plug the arduino into a stepper shield...
5. I know the TB6560 board would work well with a parallel port and linuxcnc, but I am unsure how I could connect the arduino to it.
