Right, MIN_LIMIT and MAX_LIMIT are not handled by stepgen or
any motion interface hardware, they are handled much higher
in LinuxCNC. To reach a smooth deceleration right at the
limit position requires it to be limited before the
trajectory planner. So, these parameters are picked up out
of the [JOINT_n] stanza by something in the motion section.
Even the G-code interpreter knows about them, as you will
get "program exceeds +X limit at line 1234" messages when
loading a program.

I've seen that memo hundreds of times. Maddening when its only 1 thou
outside of that limit.
Much LESS maddening than if you didn't have homing and soft
limits set up, and you started in cutting material when it
hit a mechanical limit and wrecked the material or a cutter
or whatever.
I'M SO GLAD I finally set up home and limits on my system.
