Ok, I found error.
Kinematics are ok and switching between kinematics works well.
X axis offset is not supported at the time.
Problem was lost encoder pulses.
Im running 8000 pulses per mm.
This was too much for hardware to handle.
I need to drop my encoder count for this hardware, sadly.
I would have liked to get everything out from machines accuracy.
Im running 6i25 and 7i77, currently Im not using filtering to get better encoder count rate.
I have 8000count per mm but now Im going to drop it down to 2000 per mm.

OK, I wasn't even considering hardware problems....

Same here, I had previously 5I20 and 2 analog servocards and 1 io card.
This setups did not had this lost pulses problem.
I still need to investigate more accurately what is going on.

Hello
Well yes.
It's now working perfectly.
Error was lost encoder pulses.
I'm using 6I25-7I77 compo and it turned out that it's max count rate is ~550 KHz when filtering is on.
I was loosing encoder pulses on rapid moves.
I dropped my encoder count on all axis, this resolved my problem.
I still need to run impeller to test how this affected my surface quality.

Nice....
How did you home the rotating Axes? Home on index with a separate Ini?
You are German, right?
