...I've found the right parameters for slice and so on, but I still have some wobble and I do not know how fix it... any suggestion?

Maybe it also helps is you just increase with the poti the current of the z-axis driver. This will give some more power to the steppers. Anyhow you should FIRST check if everything is more ore less aligned and run smoothly. If you thing yes, that you can go for this. If you don't know how to do search youtube for "A4988". This is the name of the stepper driver. I still have no idea if this still supports only 1A or if it is already upgraded. It looks like there is still the R200 resistor (0,2 Ohm) soldered.
