Tool path simulation - nx ignores arc paths :/

[CamExplorer]

Hello everyone, since yesterday I am trying to solve the problem as the topic above.

I made my own kinematics (5axis machine, itnc driver) and NX is runing tool only on points (machine control settings) in tool path simulation mode. I describe this problem in link belov becouse someone had have same problem like me:

LINK : tool path isue

PS. Strange, because machine code simulation MODE works fine on my simulation (arcs OK, plane spatial OK , etc)

Unfortunately still no solutions for tool path simulation (arc paths) ... Ehhhhh

Any idea how to fix it?

I'm not sure there is enough information here to tell what is happening.

Have you shown this case to GTAC?

Currently I didnt show this to GTAC because this is my first time when I get this "rare" issue

According to the guidelines I used for kinematics .MCF file from similar siemens_sim file. This is the standard procedure + the possible modification of kineamtic chains and channels in Machine Tool Navigator. Mayby I should re edit again copied subprog file which contains ToolChange.prg (cse_driver\heidenhainTNC\subprog) ? ? ?

I made some my own kinematics & postprocessors before and I have never met this problem with common Tool Path Simulate.
