It was indeed a fun project, but It never worked very good. Stacking rotational axis in series, like the typical robot arm, requires stiffness and precision of the parts and bearings that is not available to the normal hobbyist, like me
I'm not sure just yet if this is a good design, but it looks cool :) It suffers from wobble in the arm when the base rotates, and there is some slack somewhere in the rotation. I'm not satisfied until it moves 0.1mm in any direction when I tell it to. Work in progress... I will open source the thing once it reaches a decent state, or if someone else wants to help develop it.
I can't believe I'm seeing a fusion of polar kappa? I love it !
I thought of setting up one with the turntable, but you overcame

Wonderful. Do you publish the firmware? Can it be customized in GRBL?
Amazing work, is it an open source?
Amazing work! Please document this! Is it open source?

is the firmware on Github?
Man, that's incredible! What's the name of the cinematic?
The arm is a Scott Russel mechanism and it rotates. Polar Scott Russel perhaps?
