It's not really intended but is a known limitation of the planners, original linuxcnc planner as well.

This is part of the reason why I shifted focus on rebuilding the tp base. Which I am ready to share the first draft of, mind that it is still very much work in progress, although quite promising so far on my own testing.

set in your ini in addition to the jerk limits.

[TRAJ]
TPMOD = tpnextmod
PLANNER_TYPE = 1

This is the different approach which I mentioned in my previous post, based on my multi-axis branch, plus a new base for the tp, path based rather than segment based.

Thank you all for the continued testing and support, I do keep an eye here even if I don't always reply ;-)
