    Hi
    In the Lead 1010 build video the guy talks about adjusting the eccentric spacers from the fully
    open position till there is no more play.

    First Question
    DO all 8 wheels need to be touching the C beam with the same amount of rotation?

    Second Question
    What is the reason for him saying in the video to rotate the eccentric spacers counter clockwise
    on the right side of the machine and Clock wise on the left side?


    Thanks for any help.

    All should touch, but rotation may differ as each part has slight differences in tolerances

    Just OCD :) practically it makes no difference, though it feels nicer when you know they went the same direction

    Yeah I messed with those thing at least an hour or two over the last couple days and there
    was no way I could find to get them all the same.

    I got them pretty good now though so it's good to go.

    I worry about getting them too tight. Is it enough to just have zero-lash in the plate assembly relative to the C-beam? I suspect that my adjustment of the eccentrics may have contributed to an offset between the LH and RH Y-axis during my first movement test.

    Correct, just dial out play. No pressure
