To improve your Witbox 1 and eliminate Z wobble, here is a part and the necessary materials to replace the original spindle with a T8x4 trapezoidal screw with anti-backlash nut:
Required materials:
1 unit of motor with T8x4 screw, 310mm in length
2 units of DIN 912 M3x14 screws
2 units of DIN 912 M3x12 screws
The motor you will receive already includes a nut, but if you want to install an anti-backlash nut (recommended to further improve accuracy), contact the seller to ensure it is included or to purchase it separately.
