    I’m not from an English speaking country, so please bear with me, I will try my best to make me understand.

    I’m considering making the 525 25,4mm update, but before starting printing I like to analyze by CAD what I’m about to print. That also gives me a very good idea of how everything is assembled.
    So while doing this, one thing felt weird, there is a difference between corner tube centers and middle tube centers.


    Here the distance between centers is of 29.4mm
    There are some tolerances, 25,8mm tubes can fit, so a 0,4mm offset.
    Everything tight down theoretically will give a center-center distance of 29mm


    But here the distance between centers if of 27,3mm

    What am I missing?

    I think I got it, it’s for adjusting the tension between X and Y.
    Correct me if wrong.

    EDIT: Uoppss.. And did the cad middle assembly wrong. It’s actually 27.5mm
    So between 29 and 27.5 it’s just 1.5mm. Yup, don’t mind this thread… pretty sure it’s for the tension.

    PS: I’m impressed by this new middle and the way the threaded rod fits now. Well done Ryan

    F&ck, Looks like I have some work to do.

    Thank you for finding that, the equations did not carry over in solidworks…

    Could you please tell what files are updated? There is no records in changelog.

    The F and J corner assemblies have a change log for the corner pieces that have been labeled with a “2” The locks should be the same but I revved them anyway to be safe. For most people this is not a big deal, not worth reprinting your parts.

    Glad to help. Indeed, don’t think that is a big deal also.
