    Looking good. What was the distance on the brackets? And on the Z-bed bracket? I might have made a typo in Openscad when I recently fixed up all the parts.

    The angles of the ported and non ported parts are different. It was a way for me to keep the apart. I will probably change them to all be ported, but with a letter or some other type of identification at the bottom.

    Currently the build volume is 200x200x220mm

    Making the platform higher will instantly increase vertical build size, but comes at the expense of longer drive shafts, lead screw, smooth rods, and a slight loss of stability, unless you enlarge the machine footprint as well.

    There is a 300x300x300 version planned that should be printable on a standard Morgan, or Mendel reprap.

    I am working on just such a build instruction. Halfway done.

    It should be fine – at least until you can print yourself a set of parts.

    Good luck!

    Fully printed Morgan…

    ID should be about 27mm

    Two 6805 is correct.

    On Morgan I print the threaded parts at 0.2 layer heights with much success. Of course, 0.1 will be better, at the expense of time.

    I recommend you get someone to print the plastic parts for you. Going the repstrap route is an adventure, but can take a very long time to get every found piece working together.

    I can do it for you for $50 plus shipping, but prepare for shipping to cost much more than the parts… South Africa is far far away…

    Yes… Brass was a slight doccumentation mistake on my side. It should be plain old copper plumbing piping.

    So, 16 and 23. I will start on the SAE branch sometime today.

    Hi Jesse,

    If you US guys can supply me with commonly available close matches to the metric parts I use, we would do and SAE branch of Morgan on github.

    This should make your lives a bit easier…

    My two machines were printed on 10% hex infill, and is doing quite well despite the sparse plastic. 15% should be more than good enough for everything.

    Two shells. 0.2 looks good, but 0.4mm layers do work fine. Go 0.2mm if it is your own machine and the extra printing time is not an issue.

    Only used 3mm on Morgan so far. To all accounts 1.75 works better for bowden, but I have 3mm down to an art now.

    Next machine will be 1.75. Building it right now…

    6805 is a bearing commonly used in bicycles, and if you go to your local bike shop you will find it as hub bearings. Get the cheapest ones – the ceramics are great, but too expensive for the use!
