      I thought this was interesting, it's hard to make out in the photos, but it looks like the larger DeltaWASP models are using a third arm at the top of the effector to keep it stable while holding pellets (or heavier extruders). I wonder how well that works with reducing effector tilt.

      Could four arms work with something like this or does that somehow limit the movement of the effector? Could one simply add another set of arms spaced 10 or 20mm above your lower arms on a carriage and then duplicate the arms by the same height on the effector.

        I suppose the third arm offers a lot of stability for the massive effector in the link. I suppose you could add 1 or 2 more arms to your delta if you wanted as long as they're all parallel, it should work, its more mass, more joints and more components to achieve precise alignment of, but why not? Assuming its well built it should offer a more stable effector. But on anything but a very large machine its overkill as a combination of rigid frame, linear rails, magnetic joints and metal (or PCB?) carriages and effector seems to result in no effector tilt, so why add more components?

          I may tinker with this idea in OpenSCAD.

          Something like a small triangular carriage with three arms around the points of the triangle using a mag-ball setup.

          It's adding 1/3 more weight, but maybe it would make the effector more stable at higher speeds?
