Simple. The screw is replaced with a ball screw (P3 precision or above) with double-head positioning support. It is enough to select a servo motor with an X-axis of 10 N/m and a Y-axis of 15 N/m, as well as a coupling. The parallel error between the screw axis and the guide rail should be less than 0.05mm. To make it simple, just install an encoder on the spindle. Note that the speed ratio between the spindle and the encoder should be 1:1
