I know you may have heard this all before....But.....
I am trying to formulate a plan to “get into” CNC machining and my first question is:
Is this circuit a “good” circuit? http://www.doc.ic.ac.uk/~ih/doc/stepper/control2/3axis/
I have seen and read a lot of posts for purchasing boards and building, but no one has commented on this exact design. So I am just wanting to confirm that this will work with some small 5 wire (yes I am going to say it) HP stepper motors. Don’t worry this first machine will be small. I just want to get my feet wet, but not get shocked.
Why not buy……..well I am married and most of you single guys wouldn’t understand. Plus she handles the money so I am in a little pinch. I have done a lot of research and looking around and think I can build the complete 3 axis controller for under $40 dollars.
