I am trying to build a CNC dividing head, but I have absolutely no knowledge of the electronics side of things that doing this will require. So I have decided to start a thread just for asking various questions regarding CNC basics rather than cluttering up the Q & A forum.
So here's my first dumb question:
My understanding of CNC basics is this: You have a breakout board which creates the pulse, width, and direction signals and these you send these to the motor driver. Then the driver converts these into the necessary format for driving a stepper. The driver also can act like a relay and feed more power into the motor than is contained in the p/w/d signal. The driver also can do fancy stuff like microstepping. Is this all correct so far?
Here's a second question: what sort of controlling input is this driver looking for? ( http://www.ebay.com.au/itm/Dual-H-B...Electrical_Test_Equipment&hash=item2ebd9899bb ) It does not take a p/w/d signal, does it? Do I need an L297 in the circuit somewhere?
Lastly, where is a good tutorial for this sort of thing, please? I mean the overall circuit of a stepper system rather than just which wire goes to the gecko board type of thing.
