    The main advantage of belts other than gearing is to reduce resonance and smoothen motor performance. This is why most use it.
    Resonance cripples the performance of steppers so anything to help reduce it is welcome. Using Digital drives makes huge difference to stepper performance and smoothness.
    Also regards Micro stepping don't think of it to increase resolution because while it does up to a point it's main purpose is to smooth motor performance. Noticed you also mentioned running Steppers at 200 steps (Full step) this would make them run awful so expect to use Micro stepping.

    They are exactly the same regards end dimensions. But C5 screws require higher spec end fixings hence why they sell C5 end bearings other wise there's no point using C5 screws.

    Right, that's what I needed to know! Ok, I'll go with belts, albeit on a 1:1....! Thanks.

    I will be going digital, yes, there seems only a marginal increase in cost of the drivers and like I said, this is an investment/reuse later so no need to buy cheap first off. There's no point; if I just want to do cheap then I might as well buy a 6040 :)

    Yep, my point was that I didn't *need* microstepping for any resolution aspect; naturally I'd use it.

    Yes, I'd noticed on the website, that's fine. Wasn't going to attempt to mix ;) but to know the end dimensions are the same is just what I needed to know. I'll model off C7 drawings/dimensions, but just spec everything at C5.

    Perfect, thank you!
