I updated from R4-SP4 to all of the updates to R4-SP9 this past week. Controller has worked fine since 2017.
After updates to current ones, everything works except Y & Z will error out with " Excessive servo lag in y or z"
Anyone know where or how to correct this? As long as I have the feed rate rheostat turned way down low it will run like a turtle. As soon as I turn it up to normal speeds it errors out.
