    How do you mount a plate to the other side? I see in one of the examples there in a second mounting plate on the gantry to allow the mounting of a "Z" axis. Do you use longer screws through the rollers to the second plate. If so do the eccentric cams still work? I want to mount a 500mm C-Beam kit for my "Z"

    Yes, you use a longer screw but you also need a 2nd eccentric on the opposite side of the wheel into the second plate. Both eccentrics will need to be set to match each other and adjusted together as needed.

    Solid V-wheels are 11.0 mm thick. You can work out the rest.

    Not trying to sound off handed, but that's not an answer. I still don't know what length screw is used to install one on a single plate, so how could I work out the length needed. I'll buy 40mm screws and cut them.

    It was not intended to be an answer as I am not entirely sure what your final build up will be comprised of. But assuming you are using (2) 3mm plates, (2) 1/4" shims, (1) 11 mm wheel, and (1) 5mm nut that comes out to a grand total of..... 34.7 mm.

    That helped a great deal knowing those measurements. I only had to add to 1mm shims.

    Thanks
