Re: rotary table drive

Sure, there is a pulse and dir circuit in the files section that is
really a simple single chip unit with some caps and resistors.

no ramp function and just a plain on/off type of start/stop unit. it
could feed the stepper driver (assuming that the FROG is not the
driver) and all you would need to do is figure the switching from one
unit to the other.
