    Holy cow, looks like someone got out the shrink ray! That is awesome looks great, and had to be a ton of work!

    actually not too much, just your excellent design copy-pasted 🙂 If you are ok (basically it is your construction), I can share stl files. Or maybe later, when everything will be working – so far I am waiting for shipping of steppers and extra bearings.

    Sure but lets wait until it has been tested, and please document it well, BOM, assembly ect.

    Very cool, I have also played a bit with a scaled down version before, this one is for 18mm with 625 bearings 🙂
    I only got as far as the rollers 😀

    Really my project is not old – it has been started about 10 days ago. But I am in sick leave now – I do have lot of time (but lot of problems as well).

    I don’t need to build a 5th machine.

    That thing is so cute though.

    Hi!

    Is/has someone build(ing) this version? I started a month ago printed the STL’s and started building. First I used 15mm conduit (used for central heating in Holland) . This did’nt work so I bought 16mm conduit at the Hornbach store.  I sumbled over some problems:

    1. The Z-axis lists a M8 Threaded Rod and and Bearing 608ZZ but the Shaft coupler does not fit in the nut_lock.stl

    2. There are two roller spacers. (1mm and 2mm). Which do I use were?

    Does someone published his build or has experience building this version?

    Regards Tjeerd

    Hi Tjeerd,

    it will not work with 15mm tubes – even 0.1mm is important.

    Most probably you have bad luck with M8 coupling nut – it is possible to find 2 different type in a local shop in Finland.

    As option I can give  sketchup file – you can modify yourself according your sizes.

    About spacers – I don’t remember exactly, one type for X, another for Y, just check what is better for belt.

    As I know, few people had build this machine, but I have not seen any publications.

    Regards,

    Vladimir
