Filawinder servo filament guide leverage multiplier

thingiverse

This setup boosts the leverage of the servo, keeping it from complaining about movement limitations, though it restricts range of motion, as far as I see no compelling reason to span a full 180 degrees anyway. A sturdy 8x32x1.25 inch machine screw with three nuts forms the pivot. First, screw the fastener into place at the base. Next, slide on the bottom spacer and then the guide, accompanied by the top spacer. Finally, tighten everything at the top with a jam nut, securing it firmly in position. Hot-glue the servo onto its designated spot. The great thing about this design is that you can adjust it to work with any spool sizes. The base itself was printed using an 0.8 mm nozzle, resulting in a slightly loose fit - let me know if you encounter issues, and I'll take steps to tighten things up. Use a hobby-grade push rod for the linkage and aim to position the guide directly at the center of your spools. Align both the guide and servo to face perpendicular angles to achieve the ideal connection. Calculate the ratio between guide arm length and servo arm length, then plug this number into the FilaWinder sketch/Firmware's guide movement correction section. This tweak should get everything up and running smoothly. Hope this setup finds its way into use - maybe it will be exactly what someone needs!
