hey guys I am sitting here watching my cnc mill atm its shaking quite a bit acceleration is 600mm/sec2 which is not that high i think. compared to every other cnc mill i have used with a commercial controller. they have jerk control and work much better. so looking forward to when we get jerk control here on linuxcnc!
but in the mean time i need a poor mans jerk control and thinking of a limit on the pid output to chop down the initial acceleration for the first moment in time just so little moves don't shake it to death andy mentioned that I could maybe use a limit component to limit the initial acceleration for the first tiny moment in time to cut down on the vibrations. how do you guys think that could work?
