TCP 5-axis kinematics

I don't understand because pin motion.tooloffset.z in xyzbc-trt.ini eample, not is refreshed whe use a tool with a positive tool lenght value.
How kinematic can calculate if not have this value .
In hal file existe connetion, but the pin motion.tooloffset.z is alway zero value.

Thanks

the pin motion.tooloffset.z is alway zero value

maybe try using g43/g49 to activate/cancel tool length compensation

more thanks.

Hi.
I would like some clarification about the kinematics parameters.
The parameter xyzbc-trt-kins.x-rot-point, xyzbc-trt-kins.y-rot-point, xyzbc-trt-kins.z-rot-point.
On my machine, I have linear, incremental encoders. The machine performs the zeros and axes are distant from the center of the table X = 830mm, Y700mm and Z 750mm.
After finishing the references the machine position for X, Y, Z has a value of zero.

Should I write the values of x = 800, Y700, Z750 in the file .ini [JOINT_0] HOME_OFFSET = X .ecc. or in xyzbc-trt-kins.x-rot-point?

Thanks

Normally you would "setp" those HAL pins to suit the fixed geometry of your trunnions.

It isn't anything to do with home positions etc.

Thanks for the answer. So ultimately, I have to set xyzbc-trt-kins.x-offset and xyzbc-trt-kins.z-offset based on the physical center distances of my table based on the dimensions of the table manufacturer and to perfect the kinematics and adapt it precisely use xyzbc-trt-kins.x-rot-point and xyzbc-trt-kins.y-rot-point and xyzbc-trt-kins.z.-rot-point.
Correct?
