Could You, please, draw and paste somewhere a sketch?

Hmm, maybe I could use the X word to specify > the d value? I created kinematics module, where I had an offset value, used for rotary joints to compensate displacement of nozzle tootip along X and Y, when rotary joints tilted the head. The thing is that the offset value was feeded in kinematics module like a HAL pin. And I think that it means - it could be adjusted "on the fly" as machine is running.
