Stepper motor with encoder = servo
Encoder ----- rotary or linear?
Get requirements straight, size, positioning, accuracy, load weight.
Put together a concept of operation.
What are positioning requirements? Accuracy X, Y, Z with in 50 micron.
Stage size 1m x 1m x1m? 10m x 10m x10m?
6 motors X, Y. Z Pitch, Roll, Yaw (you really need to Roll a microphone)
Pitch and Yaw will effect position of tip of sensor
What type of guide rails?
Consider motors with brakes -- so there is no hum from holding current to motors.
What will be driving this? Controller?
Position command (software)--> PC USB interface--> micro controller (Arduino) --> micro controller firmware--> stepper driver --> stepper pulses
read encoder --> encoder controller interface --> controller --> controller firmware --> feedback algorithm
RAMPS 1.4 will control 5 motors
You have a parts list before you have a design?
Good luck
