Subject: [alt-beam] Re: let me be clearer (was stuff)
Nope, not clearer. Here's a question, is what your trying to do to use the
drivers in a push/pull fashion? IE the motor drivers point IN for on side of
the motor, and the point the 'other way' for the OUT side of the motor? If
so, that won't work either. :-) But no, still don't understand. I'm really
curious now though, as to what you mean.
