it is compatible with mesa default setup, but you need add the jerk parameters in the ini file, look at the axis_mm_scurve.ini file
I wanted some feedback from the community about s-curve, there a few considerations to make, not just jerk spikes
I think there are some choices to make, when trying to respect jerk limits, we can:
1 - Slow down at curvature changes: reduce Vel so the centripetal acceleration change is manageable. (this defeats high-speed machining)
2 - Modify the geometry: insert transition curves (clothoids, Bezier, splines) that have gradually changing curvature. This eliminates the discontinuity but changes the path. (when G64 Px is too small you will see jerk spikes)
3 - Accept the spike: the programmed path has a curvature discontinuity, so the motion will too.
There is no fourth option. You cannot maintain velocity, follow the exact programmed path, AND have smooth jerk. we need pick two.
