LinuxCNC S-Curve Accelerations

I tried to follow your instructions, and it works ok for me.
I suspect it maybe something with the custom tool table which is missing from default, could you share that?

Hello,
I am sorry my bad ...I am too much focusing in something and then I failing in others ...

I have tested some toolpaths till now ... Infinite spikes are gone at tp 1 and 2 at paths where it defenetely were in the past ... I noticed that TP1 during its startup with testing code 1_1001.ngc spiking much with servo time (if we take 250us as our goal - for 1ms it is fine) ..

Default TP0 and TP2 do not this behaviour ...

dark blue from scope pictures in the attachments then TP1 is spiking at each segment change over 200us during cloud of points its repeating spiking too.. 

I notice that switching between TP1 and 2 is not possible sometimes it creates error and switch me back to TP2 from TP1

thank you E.
