Not sure how it would work with servo's Andy, but despite my jog dials on the sheldon having to navigate thru the encoders to get back to motion's jog inputs, they are as realtime as you can get when 90% of that signal path is in a 200HZ thread, and I don't get anywhere near halui with any of that. Its real slow. I am using it to stop and by way of halui, unhome if a driver faults, and the halui action might be up to 2 seconds after the machine stops before the home star dissapears.
