Modified Prusa I3 single motor Z mod complete

thingiverse

This single-motor Z modification prevents X axis misalignment in typical two-motor systems due to motor synchronization issues. It utilizes Cupcake Z parts for implementation. Key components include 2 each 5mm bore GT2 2mm pitch 36t pulleys (SDP-SI), 4 each 624ZZ bearing idlers (Ultimachine), 1 each Cupcake Z belt GT2 2mm pitch, 6mm wide, 424 teeth (SDP-SI), 3 each 5x11x4mm flanged bearings for the 5mm Z screws (VXB), 1 each 5mm to 5mm flex coupler (Adafruit), 8 each 4mm bore fender washers and regular M4 washers (Ultimachine), 4 each M4 x40mm capscrews (Ultimachine), 4 each M8 nuts as spacers (Ultimachine), 2 each M5 standard washers (Ultimachine), and 4 each M4 nylock nuts (Ultimachine). Note that the stock Z threaded rod should be extended to approximately 13 inches for the motor side and 15 inches on the right side due to modifications. Assembly instructions include placing the stock Z smooth rods' caps, switching pulley hubs with the hub down, adding M5 washers between the bearing and pulleys, and using lock nuts on the M5 threaded shaft in tension rather than compression. This modification ensures X axis tramming remains consistent while simplifying motor operations and reducing stress on the Pololu motor. Optional crank modifications can be made with a longer 5mm threaded rod for manual adjustments.
