Thanks guys for your answers,
as you can imagine I'm not a magician with the inverse kinematics ... and before I start the construction of my first 3d printer and burn a bit of money with a wrong project, I need some certainty.

I also think that the parallelogram is a sort of redundant kinematic system which ensures that the effector remains parallel to the bed
in fact for the purposes of kinematics is treated as a single link
but in action could be critical
your optimism pushes me to try, but if I am wrong I have to redo a lot of stuff ...
@ sheepdog43
yes, this design allow great print area and great freedom of effector (single cardan joint allow 45 ° + and -), but I'm still not sure of being able to control him :-(
However I do not want to make a Chinese copy of the project and use pneumatic actuators, but I'm just very fascinated by its minimalist design, and I'm looking for some kind of confirmation on the function of the single link
