Hey Jon, I really like the looks of your board and it's very obvious
a lot of thought has gone into making sure all the "goodies" are
there. Could you describe (briefly) what the rest of the pieces of
a full system with your board at the center might look like i.e.
examples of the software front end to this (I'm assuming it's
set up to run ideally with EMC since I don't know of other software
that has the ability to read quadrature encoders back and drive
s&d out (I could be wrong here ... probably am ...). Also, from the
output side, what sits between your phase outputs and the motors
themselves, i.e. how do you get your phase signals "beefy" so they
can move the motors. I know there's a power supply matched to the
motors current and voltage requirement ... what else (This may be
a stupid question ... but hey I find out daily I know less about
everything than I think I do so I have no shame). Nice job on
the design for the board!
