@ A2
Thanks for the offer on the abs.
20. Can you explain your reason for thinking equal length arms will stop the zig zag problem? Mathematically the two arm lengths are included in the formulas as two constants L1^2+L2^2 and 2*L1*L2. Since you are solving for the vector, the arm length ratio can be any length as long as you don't violate the limits of arccosine. Changing the arm lengths to be equal might have some mathematic optimization, but I don't see how it can change the position.
21. The throat diameter is 74.3827
The reason I picked 90t worm gear is mostly arbitrarily but I wanted a gear large enough to take the strain of the arms without damaging the teeth. I don't understand you’re logic that a larger worm gear will reduce your print envelope size unless it is intruding into your printable space.
@ JamesNewton
Perhaps the simplest solution would be a printed coupler that is 1/2-10 thread on one side and 5mm on the other. Like what is used for the prusa z . [www.thingiverse.com]
Most of the load is axial so I wouldn’t expect too much flexing
