(snip) Simply, all the drives have their Direction pins tied to a
single Direction output pin on the computer. Each driver gets their
own independent Step pin. Axes going different
directions obviously can't be stepped simultaneously, but must wait for
a microsecond or two... a delay which wouldn't be noticed by the motor.


Doug, what type of equipment would you use this technique for ? It would
appear for some type of "single axis at a time positioning", with when
in the rare lucky event that more than one axis IS going the same
direction, one could run simultaneously, though that would be an
interesting "post" method from a Cam proggy.....

Clearly, the programmer can account for this, as does the method of
wiring the Gecko by just tieing them all together....
So it looks like Only the fixing of the timing issues are your
question, correct ?

Mostly, I was curious to the application.

Thanks,
