    Was just about to ask whether I have to switch from belts to direct drive. Do I need brakes on the vertical servo's? It's gonna be lifting 150kg after all?

    You have to design to your own requirements but lifting 150Kg then yes I would go with dual motors with brakes, doesn't need to be servo motors thou, Closed loop steppers will do the job perfectly well enough.
    -use common sense, if you lack it, there is no software to help that.
