Dave,
Servos traditionally were harder to implement due to greater wiring
complexity, add-in servo cards, limited software choices, many more tuning
parameters, cost) when they were only the traditional servo amp with motion
card. For the hobbyist it was pretty much EMC with a Servo to Go card. Great
performance if you can pay the price and get over the learning curve. Now
that Gecko has made the G320/340 series drives available servos have become
about the same cost as steppers and only slightly harder to wire and tune.
Pretty much you set them up just like you would a stepper as that is how the
controller program sees them. So you can use any step and direction program
you want, don't need a $800 motion card and only have to connect additional
wires for the encoder to the drive.
In my view it has opened a whole new level of performance for us hobby class
people.

Hi Tim,
I had thought Servo's had all you said, but that they were a LOT
harder to implement.
There is an interesting link here :
