TWIN OR QUAD LEADSCREW DRIVE FOR Z-AXIS

thingiverse

A custom lead screw drive system for a single stepper motor utilizes two right-angle transfer boxes driven by a differential gearbox. This setup requires two sets of transfer boxes for a quad lead screw configuration, supplemented by a NEMA17 dual shaft stepper motor. To ensure accurate rotation, one differential box must have its input shaft reversed while maintaining identical gear mounting in both differentials.
