Hi Jeff,
Sorry, I probably didn't phrase it right. I understand that deceleration
on soft limits for joints on a non cartesian machine is a computational
nightmare. What I am after is to specify soft limits in world space,
just like a cartesian machine. I am interested in it for my lathe but

No, it's not currently possible. It would be a welcome topic for
improvement.
Right now, kinematics is confined to the realtime trajectory planner, so
nothing is known about it at the time soft limits are being enforced in
task.
A naive approach would be to put a copy of kinematics into
I'm running Git master at the moment.

Is there an option to make soft limits to work in world space on a
non-cartesian machine? I notice now I am using my kinematics module soft
limits apply to joints rather than axes. In cartesian mode the machine
comes to a graceful halt if you try jogging into a limit. In
non-cartesian mode the
