'source for stepper controllers?'

Does anyone have a recommendation for a stepper motor controller board, with
perhaps serial input? One that will drive big fat stepper motors? Also, a
source for a couple of big steppers?

Thanks, Bob

Well, my recommendation is, of course biased.  My company makes a good 1.75
inch square module (15 pin SIP package) that will drive up to 500mA per
phase with full features (half step, auto or external step, free spin,
etc.); alternatly we sell just the stepper chip that can drive four MJE3055T
power transistors for very large motors.  Datasheet with hookup schematics
are on our web site at http://www.netins.net/showcase/elab

The stepper IC is the EDE1200, in the 'Integrated Circuits' section.

As for driving it serially, put one of our EDE300 PC Interface ICs on the
front end.  It will control up to 4 steppers depending on how much control
you need over them.  A datasheet for it is on there as well.

As for stepper motors,  try B.G. Micro at http://www.bgmicro.com
