I got the closed loop speed control working last night but it needs changes. The best I got so far is the use ff0 and set a value that gets me close to the command speed and an I gain of .001 homes the speed in real close in a few seconds. I want to try to replace my lowpass filter on rpm feedback with a limit2. My large negative spike when trying to thread was limited in rate of change but lowpass kept it in the loop for a while and threading didn't work. More experimenting to come!
