I don't have a great need for it with my machines, or the time/brains to
implement it. It just seems like a feature we really should have.
I'd be willing to participate monetarily in some sort of system to
incentivize the inclusion of jerk control. Perhaps an open-source feature
bounty? Does the community want to consider that sort of thing?

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?
Regards
Andrew
