3 axis motion control- where do I start?

I have to develop a hearing aid hybrid test system which will test an array

of hybrids. I already have the individual hybrid test code but need some

guidance with the motion control. Does anybody have any good references

for me on what aspects should be considered. All I really want to do is
step
and test but don't know much about motor types stepper/servo etc, limits,
calibration etc. Any tips would be greatly appreciated.

If you're willing to spend a lot of money ($4-$5 K), you can get a lot of
this motion stuff ready made. I bought motors, controllers, stages, etc,
from Velmex (www.velmex.com) and found it was fairly easy to program.
Considering wh
at my time cost, learning all about motors and putting
together everything myself probably would have cost more. They don't have
LabView VI's, but programming their controller in LabView was not too
difficult.

We use http://www.jrkerr.com/index.html motor control system. This uses
low cost Pics and a serial network. The drivers are a DLL and can be
called from LabVIEW. I have built multi axis devices and it has worked
real reliable. (No problems).

A company called Compu-Motion has experience building low cost hardware and
software for mult-axis devices. Compu-Motion web site is
www.compu-motion.com. Compu-Motion could help you build the hardware or
software.
