I still get acceleration violations but the magnitude seems less

I can not upload the file because it exceeds 1.6mb ... I need to upload it over external source  www.uschovna.cz/sk/zasilka/UA4I4N3SK2XGF2W6-TNV/

I checked the @ruediger123 codes and there are another spikes in the ramps...

I've checked all the reported spikes, and the issue is not the new s-curve in itself, but the trajectory planner architecture, we will have to do a much more involved refactoring, will look at Tormach work, maybe talk with Rob if that happens, and take it from there.
The current scurve is best that can be done within the limitations of the current tp architecture.

Can you elaborate on what are these architectural issues?

spiking is present maily during movement at same vector .. when vector of speed is different, spikes are gone

The curent scurve is architecturally limited to works on segments, and the transitions between segments don't respect scurve limits.
We will see if we can improve blending and look ahead to solve this issue.
