Hi Nerd here again,
I have big problem.
This is working good, i can turn the thc on and of via glade panel button :
Now this is problem :
What ever i do, it is not working. The message is mostly, thcud.velocity-tol does not exist's...
Both pin's are available in halmeter in section pins
Orginal the example is setp, this works good, but is not handy in practice way's :
Please help me.

setp thcud.velocity-tol 0.05Please help me.

looks like thcud.velocity-tol is a parameter rather than a pin so can only be setp'ed
If changing this "live" doesn't cause any issues the easiest fix would be to change it to a pin

@PCW,
Thank you for the comment. I have tried to fix it to make the connection as a pin output and also as a variable output.
I see it the value's are available in halmeter, but the connection can not be made in the hal file section.
Maybe i must try to connect them with python script.
Now i was looking at the thc when the program is working. The z-axis motor is responding normally on the thc up and down input signal. So this go's well. But the Z-axis dro on the screen is not changing when the TCH is enabled.
It looks like the correction value of the THCUD is not linked to the actual z position.
When the THC is disabeld, the Z-axis dro value is oke en normal responding.
thcud.z.pos-out value is about -1600 at the screenpicture. This value should be on the z axis dro displayed.
See also the picture of the z axis output value's
This is my hal section, i looked a long time to look what is wrong, i have cleaned it up :
Is it possible for me to experiment with the THCUD.comp file? Is it only possible to make a comp file with halcomp in terminal?
Or is it possible to change some code directly in the THCUD file? This is new for me, but maybe good to practice.

Update :
I was trying to solve the thc z axis dro value problem, but that is not as easy as it looks.
So now i have made a real time hal component file with : sudo halcompile --install grotiusthc.comp
Hopely now i can get the z-axis dro value on the screen.
