ronf1964 Posted February 27, 2017 Share Posted February 27, 2017 Any thoughts on the best way to control two axis moving in a vector? Right now we are bringing our gap voltage into and analog channel and using timebase following. The problem with this is the process is erratic. We use reverse look ahead to change directions if we drop below our set point. Link to comment Share on other sites More sharing options...
curtwilson Posted February 28, 2017 Share Posted February 28, 2017 You are doing fundamentally what all our Turbo EDM users do. How to tame the motion resulting from the noisy gap voltage measurement to get smooth but responsive motion is the challenge. Unfortunately, those who have done it successfully consider it their "secret sauce" and don't let us know the details. You will have to experiment with various digital filtering algorithms.
