Opto Endstop X Adjuster
thingiverse
The given text discusses modifications made for Opto Endstops shipped with a Prusa Mendel Kit. The Endstop PCBs have SMD light barriers and only one hole to fix, so a slot was planned in to prevent rotation. Future adjustments include adding a wheel for the adjusting screw and possibly printing the opto bar horizontally to avoid a filled slot. For assembly, tools like 3mm and 2.5mm drills, a drill press (if available), M3 thread cutter, M3 x 40 and M3 x 25 screws, square nuts, washers, nuts, and a small spring are needed. Instructions for building include finishing the clamp bar holes, cutting threads in the holes, drilling the opto bar holes, assembling the unit with screws and nuts, and deciding on placement of the opto bar. The adjusting screw should be positioned at the top for easy access, and the unit is ready to use after fine-tuning.
