This is to sync the 2 Z axis motors together on the FT5.
The front spindle mount plate uses the stock screws and channel nuts for the bottom and 6-32 screws to attach front bearing spindle mount to the top and bottom of the spindle. use the spacers as needed to allow for a screw to pass through both mounts and the spindle. I used 4 spacers two tight and two wide 1 of each per bearing mount. the slide mount and toothless spindle takes a bearing with a 8-32 screw and washer on the bottom use the spacers in the bearing here as well.
The belts I used. https://www.amazon.com/gp/product/B0CQP34D6V/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1
