Louis:

The Mach1 or Mach2 ocx can be used by VB developers to write applications
to do pulseing. Mach2 is stable at 35Khz with no more than .000040 second
jitter in Windows on most systems. Mach1 is as stable at 25Khz . The OCX
interface of each allows a VB application to do stepper motor control from
windows as easily as calling routines like LoadGCode() or
StraightFeed(x,y,z,a,b,c) from your application.
It is still a commonly held belief that Windows cannot step in a stable
fashion, but the diagnostics screens in Mach2 (cuurently released in alpha)
will show you in detail the stability of the pulseing. It is no longer true
that Windows cannot do smooth movement in real time. My 1Ghz machine is
stable within 5uS at all times in its pulseing. It can even read and send
email and maintain this stability. Mach2 even has a screen designer to
design screens to mimic your application's needs and you can use VB to add
more buttons you control.
If your in XP or Win2K I suggest you download the demo and give it a
shot. Even the demo can be used to develop your own application.

(Just an unabashed plug to clear up this "Windows can't do it thing...)
