How is every body doing i am doing a senior project and the project is about controlling a 3 axis machine and let say kind of a pick and place machine. It is mostly and idea for now not sure what the whole thing would be like but surely it would be able to pick some up and place it where needed. I be using mach3 as the controller software which would connected to a parallel port. so i need a controller circuit that would control three stepper motor in the range of 12v to 24v tops.The project require us to built a controller, so we can't buy one. I would be using small stepper motor no big stuff. I would basically a shelf with 3 axis frame attached to it and we will move stuff around in the shelf from one slot to another. Best description would be a "wending machine."
