If might be important to deinstall 2.9pre in synaptic manager prior to trying to reinstalling current 2.9pre. The procedure to uninstall the installed version of linuxcnc in Synaptic Package Manager can be seen in the video I posted.
But I'm really not sure why you insist on not using the official 2.8.2 ISO and update that to current master.
[edit]
maybe there is a misunderstanding and you already have updated to current 2.9pre? Have you checked if millturn config is available in the configuration picker?
[edit]
this here might help to find where to look for the sim config:

yes, I got there now I have version 2.9pre under Dabian 10.
I am now looking to install the switchkin branch with buildbot.

OK, thanks ,
it works I didn't understand that it was necessary to open an xyzac simulation and then save it.
the language barrier is not always easy ...
I will now put my config.
it is much simpler than all the compilations that I have been able to perform (search for all sources) etc ...
thank you all

Anyway, I'm glad you got it working.

That is not really necessary. The reason why I wanted you to check the simulation configs is because that is an easy way to find out if you have 2.9pre with switchable kinematics installed.I didn't understand that it was necessary to open an xyzac simulation and then save it.
Anyway, I'm glad you got it working.

Hi look through your configuration file, it seem have to put offset value in to .Ini file instead of Hal file?

Me too ,
my configuration works very well now, I just have to go and machine parts.
thanks again

Yes , it's possible with "HALCMD" commands .

one last question, what are these two tables for in the linuxcnc xyzac-trt interface. Is there an inflance in the position of the pivot center.
or the settings of the pivot center in the .hal or .ini files are sufficient
Thank you

The first table is to change the helical tool paths in the example program and the other seems to be for experimenting with the rot-point But these are not necessary.
The important thing is to get the Y,Z offsets and the X Y Z values of the rotation point right.
Nice to see that you got it working too.

Hi, I have a problem setting up TCP kinematics.
Switching between kinematics works well
but in reality the movement of the machine is chaotic
Numerical coordinates indicate a slight change.
Machine is gantry Y on version LC 2.9.
in my ini :
In my hal:
In my M128 code:
In my M129 code:
How to set parameters in HAL file correctly?
On those videos I switch the kinematics using HB04B macros and generate the movements with the mpg wheel
Please help.

Note that the xyzbc-trt-kins are for a setup with a rotary table (c axis) on top of a tilting table (b axis). You seem to be using a machine where the b and c axis is in the head and that requires a different kinematic model.
You might want to have a look at 5axiskins:
