    A thought just crossed my mind…are the holders for the 8mm rods in the z-mounts supposed to be drilled out? Or are the bottoms flush with the main surface of the two mounts.

    In other words is it supposed to be 440mm from platform to platform, or from z-mount surface to z-mount surface?

    Thanks,

    I suspected that they were supposed to be. A picture wouldn’t help much. The problem is that the top platform ends up not quite parallel to the bottom platform and causes the bearings to bind.

    Are outside PVC supports supposed to bend around the inner ones (under tension)? Mine do, but I end up with an upper platform that isn’t parallel to the base. I’ve cut the the supports to be 452mm and 459mm (per the BOM). Are those dimensions correct?

    Thanks,

    6805 bearings are used for the top of the 22mm pipe and for the tool head.

    I’m building one (albeit with mostly metric parts) and I would say that the 5/16″ rod would work IF you ensured that the nuts fit correctly into the printed parts and the tubing. One issue I ran into was that the M8 nuts are not force fit in the 15mm tubing. I used superglue to make them stick (epoxy would probably be better). I would check and see how 5/16″ Nuts fit in the various parts.

    I’m sure Quentin will have some input, also.

    I was just thinking (after I lost one of the captive nuts in a leg). Can’t all of the feet be ported? At least that provides small opportunity to correct the situation (and is one less type of part to print).

    One thing missing from the BOM is the 6805 bearings. How many does it take? I count 2 from the assembly instructions, but I want to make sure before I place an order.

    Another basic question. How solid did you print each part (how many shells, infill %)? Do any of the parts require more substance than others?

    Thanks,

    Two questions:
    1) The drive belts are not listed in the BOM. What belts did you use?
    2) Which of the fasteners (if any) in the BOM were use to attach the z-mounts to the bases?

    Thanks,

    The first issue I’ve run into is PVC pipe sizes. I was able to make the supports work with 1″ Schedule 40 PVC if I remove the “Rib anchor” from the part that goes into the pipe. It’s a snug fit.
