Maybe what's needed is a stable and well supported real-time OS. Xenomai might work. But even better is a more modularized Machine Kit architecture that lets you run the various parts on different computers that each use a different OS. The real time loops could run under a true RTOS, then

Personally, i insert more limitation in my kinematics for generate somethings similar to "soft limit" ... but the only way is possible to do thes is with a if statement ... at every cicle of kinematic save world->z to your var than control if yourvar is equal or not to your limit at these
