    Default Re: Redesigned Y-Axis Carriage with Rotary Table

    No, not the nut mounts. The flanges on the nuts in the red circles should be where the blue circle is.

    I see, but how would this make tightening easier?

    Sorry, I'm really slow on that one...

    It eliminate the need for a 12" extension on your ratcheting wrench and remove the motor that would be occupying the space your wrench needs to be in.

    Surly that is just an Allen key job to tighten the cap head screws?.....either side the space is the same with the screw in the way...……...OK, so the nut is more to the outside (right hand side) of the bottom face and what you are saying is the cap head screws in the flange will be easier to get at from the right hand side with a ratchet wrench.....….once the screws are in finger tight you don't need a ratchet wrench to tighten them, just a longish Allen key.....but ideally then I suppose it WOULD be better the way you said......Ishi is just getting too lazy to redraw his pet subject......LOL.

    I mounted them nut facing motor because this is what NSK did in their video:



    I wonder if the orientation matters. I can't think of a reason why it would, but I would like to make sure, because it will have an impact on several components if we want to benefit from full potential travels on all three linear axes.

    Default Redesigned Support Mount Flange

    The flange on which the support mounts are installed on the X-axis carriage had to be redesigned in order to provide clearance for the flanges of the nut mounts.

    Of course it matters which way around you mount them. They only work in one direction.
    Um .... let me think about that again ....


    Cheers

    You should round or facet all inner corners.. any sharp inner corner is easy cracking point.

    I believe this is what I am doing. If you see any in need of rounding or faceting, please let me know.
