we have Properties in the PC for configure the behaviour before and after the Toolchange. Give them a try, it's normaly not needed to change the Buffer here .
If that not fits you expectations of output please give me some more informations on the created Post (NX Version, PC library version, Controller, used Layers). I tried to get the Buffer output with NX12.0 but i not get the same output. Maybe you can also provide a sample post here so that i can do some testing with that buffer.
Thanks for the replay,
NX version: 10
PC Version: 4.2.2
Controller: Sinumerik 840D
Layer: 1 named AYS and other named Bost(Manufacturer). I know that is not the best order way, but I am beginning in this issue .
It is all Off in Additional motions.
I do not mind overwriting the existing buffers so they do not appear, but do not leave templates without the option to remove them
I can share with you the post if you think that it is necessary.
the G153 movement in your output is before or after the toolchange?
When it is before the toolchange then the reason is that the properties "Return before First Tool Change Pos" & "Return Tool Change Pos" are set to Z XY/ Z in your post. Switch them to NONE and it should work.
If that is not working and you mean the return movement after the toolchange please send me the post to take a look into it.
