I am deciding on what I want to drive and control my servos and was looking at the Rutex site and came across this page:
http://www.rutex.com/us/cart.php?tar...&category_id=4
It is showing a servo overshot of 295 steps. I don't know much about the other info on the graph and I doubt this servo is optimally tuned, but I was thinking that 295 steps would be WAY off and you wouldn't want this in normal practice. Gecko throws a fault when the servo is off 125 steps from where it should be. That also seems like a lot. If you were using a 5 tpi screw and a 2000 steps per rev encoder, 125 steps would be .0125 inches off. I guess I'm trying to find out what the typical error is. It doesn't make sense to make a machine within .001" with precision ball screws and slides if the servos aren't that accurate. Thoughts?
