You might borrow from GPS reverse solver libraries. They find the intersection of sphere, relevant to HEXA printer.

Feynman's electromechanical pantograph idea was popularized in a sci fi anthology I read some years ago. Waldo, it was called, I think.
He refers to the problem in the space dimension and is stumped by its insolubility on the time dimension. It takes "forever".
The promise of the RepRap was as I first heard it that there would be wealth without money. There would be some many of the darn things t

Bateson's leadscrews can be threaded rod, precision threaded rod, Acme threaded rod, precision Acme threaded rod, ball screw rod, precision ball screw rod, or unthreaded precision rod with spiral ball nuts; it doesn't matter. Those are the classes of materiel offered by my suppliers. Bateson isn't specified by what is built but by how it's built.
One assembles a single X axis and uses it to run o

Reprappers
My design for Bateson uses 12 identical leadscrews in groups of 4 for X, Y, and Z, in a cube, and suspends the cube on the diagonal to eliminate backlash as noted for accelerations below 1g.
This has the peculiar effect of changing the base of replication from 2 to 12. That is when the machine replicates x generations there are 12x axes, not 2x machines. Not quite the desired 12^x basis for repl

Reprappers
Hallo.
I seek a machineable wax flistruder and can offer a bounty. Mommie and Daddy left some money. They won't pay for my cigarettes and I'm trying to quit anyway.
Is there a machinable wax recycling filstruder extant?
Bateson, my RepStrap, boots from Unimat One to a single self-replicating X axis for <$50 and contains 12 X axes held with cuboctahedra in a cube extended to octahedron.
It

Bounties
If they were available in my previously selected stepper motor / leadscrew combo size I would add disc / hole magnets to my lead screw nuts facing North out without loss of generality and add at the stepper motor face a similar or identical magnet facing North out to form repulsive pairs. To home my machine I would simply overtravel my leadscrews and jam the steppers...but they wouldn't jam. The

I don't have a sig or a file to attach...other than 13 minutes of me dial-gaging bits of 5/16-18 threaded rod in MP4 to get some SPC on my build.
I'm building a Unimat One RepStrap called Bateson; is the name taken?
5/16-18 or M8 threaded rod fits nicely in the spindle bore of a Unimat One.
Aside from that...it's a cube, Darwin / Sakura style, and it's minimal--the leadscrews are structural du
