I'm planning a major upgrade to my homebuilt CNC Machine. My current thought is to use Gecko's GRex to send step direction signals to Rutex R2010's. As the Grex can generat step/dir signals very quickly I want to use the largest line count encoder that I can. The Rutex website lists Encoder speed of 200,000 steps.
Assumeing this meens 200,000 steps / second...
200,000 steps/sec * 60 sec/min = 12,000,000 steps / min
To achieve say 3000 rpm...
12,000,000 steps / min * 1/3000 min/Rotation = 4000 steps / rotation
If 4 steps = 1 line count than would a 1000 line count encoder be the maximum that I could install without lowering the top speed?

Your figures look ok to me for that speed.
Also does anyone have experience with the Keiling KL34-170-90 Servo Motors?
