[Halld-tagger] FW: goniometer quote and design

[Elliott Wolin]

Hi Ken,

Concerning the Ethernet-based XPS-C6 controller, do you know if all you 
have to do is tell the controller to go to some 6-axis position, or do 
you have to direct the controller to get there axis-by-axis, or must you 
do something even more complicated (e.g. start motor, speed up, slow 
down, brake, stop, check where you are, repeat, check for overshoot, 
back up, etc)?

Our preference of course is to simply use a single command to tell it 
where to go and not worry how it gets there.

Thanks,
