Does anyone build offer a finished system using geckos? What sort of acceleration/velocity can you get with a servo system with small motors?
I currently get 275mm/sec^2 accell and 1000mm/min velocity without loosing step, using 10amp power supply, nema 23 0.9degree 250oz-in motors, using geckos with micro stepping. My the motors are directly coupled to the screw, I would like to do the same thing with the servos. I'm using preloaded 5 tpi 15mm ballscrews and linear guides.
I think what I'm looking for are brushless servos with 1000 line rotary encoders and using quadrature.
Also I understand that you can home to and index mark on an encoder. I'm am interested in how this works, I think it would be more accurate than using homing switches.
