    This is correct. Hall sensors are configured as “Max” in the firmware, and should be configured as such. It has to do with the reference of the degrees of the arms, not the actual bed zero. This is why it can be confusing.

    If you take a look at the images in the Smoothie arm calibration under the support section is may become more clear where the home zero position is.

    Yes, it can be a positive distance, as long as the home position is not in a position before the end of the bed. If this happens, you can miss a home, and the machine will try to turn its own head off…

    Hi Crow,

    Drop us a copy of the config and config-overide files here.

    The dimensions above are for the latest calibration STL you printed right?

    This happens when:
    – The Theta and Psi wheels are not printed completely round
    – The Theta and Psi wheels are not the same size
    – The arm segments are not exactly 150mm (or whatever you set in the firmware setup)

    In selfbuilt systems you can get combinations of the above…

    There is a calibration procedure with a special model that you print, and a spreadsheet can assist with the settings. I will update it this week and add it to the Morgan site probably this weekend.

    Will let you know when it is up.

    Morgan 2 has machined hinge joints with 15mm OD tips for the arm printed sections. The bolts just keep it together.

    Press fitting involves driving the bearing over with a hammer…

    The new guide will be ready in three weeks, after we completed the first build course. It is always hard to write a guide before you know what to tell people…

    I will start publishing sections of it soon.

    M4 bolt is not quite sturdy enough to hold the arms stable during printing. You need something with a larger diameter. I found using M8 bolts with 608 bearings did not give the right amount of stability either…

    You are welcome to modify away. Just remember that most of the design choices was paid for… in failure 😉

    The Lilian in the picture is an extreme low cost version of the Morgan Pro 2, in that you use 15mm copper pipe in stead of machining the drive rod or the arm hinge mounts, and all the plastics are printed rather than manufactured in a factory. The bearings are press fitted (needs a bit of work with a wood block and a mallet to get it installed.

    Of course, when you build it you are welcome to interpret it as you like… That is a common occurrence amongst those brave enough to build a Morgan from scratch!

    Hi 100ideas,

    Jumping the gun a bit, but the Morgan Pro does have a solid bar as the Psi drive shaft.

    I will be publishing Morgan Reprap 2 in a week or two. It is the lilian code on which Morgan Pro 2 is based.

    Hi Mike,

    No, arc movements are not implemented in the old morgan marlin fork. It is probably going to take a lot of work to get the old marlin running it, and I personally don’t work on it any more. The only two machines I have running Marlin is in the Morgan display in the showroom…

    All of it is implemented in the new Smoothieware firmware though… If you need those movements, I recommend getting a Smoothieboard or Smoothieware capable controller.

    You may have to hack the kinematics into Repetier yourself…

    I don’t know anyone in Toronto yet. Let us know if you found somebody.
