    On the original design, the x-axis rail needed to be an extra 3mm wider then the outer edge of the base assembly. Was this taken into consideration on this bundle? I havent had time to fully look at the dimensions of rails cut.

    We did our best to ensure that this version is as modular as possible and in doing so made sure that the x axis rail could be extended or shorted along it length creating a machine that can grow according to the users needs. So yes its working great, and in fact we have had one of the early betas in the wild for some time with Team member and Project Maker @Ariel Yahni making great Projects.

    Thanks brother! :thumbsup: but props go out to you guys in the community for refining these designs to awesomeness, the original designers and of course the whole OpenBuilds Team because they were are amazing in coming together to make this happen.
    We are so happy to finally be able to offer a group of proper cartesian style router systems, its always been something that we have wanted to do and it's great to be moving forward in this direction.

    The actual length is not that critical. The extra 3mm comes from the 1.5mm on each side the plates are away from the face of the y-axis c-beam. On the original build the 3mm longer rail allowed the y-axis rails to sit flush with the outside edge of the base frame for easy squaring of the machine. The 3mm can also be handled by insetting the y-axis rails 1.5mm for a total of 3mm. If you take a look at Marks Sketchup model he shows the inset y-axis rail option and my original Sketchup model shows the 503mm long x-axis c-beam. Both options work well.

    With the y-axis rails flush on the base frame and x-axis rail length equal to the base width, the plates are forced out of square like so /___\ causing inaccuracy and undue wear and tear on bearings, wheels, nut block, lead screw ect. The Openbuilds v-slot / c-beam systems are very modular and as long as the proper care is taken during assembly to ensure everything is square and parallel you can make the rails any length you need. :thumbsup:

    Will the SPHINX end plates be made available separately so that I can mount them on my machine?

    Mark mentioned in one thread that you will need to contact the folks at the store for information on this.

    Interesting that didn't go with the 2" taller and double nut version of the plates. Any reason why?
    Guess I will have to pay attention to when openbuild sales happen now. Was contemplating cobbling one of these together.With a bundle now available, price is becoming my only point of resistance.

    Hello @Comedie
    @Kyo and I talked about this, and from what we gathered from the taller builds out there is that deflection seemed to be an issue with the 2" taller plates. We wanted to maintain the low profile stout nature of the original design so we settled there. On the nut blocks the single anti backlash does just fine on its own so we saw no need for the extra cost there.

    Hey guys just a heads up. We updated the build with an easier to understand xPRO controller diagram in tha main build page that should help to see how to easily wire up the machine to the xPRO controllers.
    Hope this helps.
