Summary

The machine actually don't print new things. All thing are transported back trough time from the future when they are no longer used and recycled in this sustainable matter.

And, yeah it also works around that issue with linear guides.

Instructions

Put on your goggles and crank out some steam & grease

This could potentially work, you would just need to make sure that the arm rotates where it connects with the gear, otherwise it will not work. Its hard to tell if it does or not based off of the pictures. It would be a pain to program most likely though

:D Solving complex geometry fast is what computer do soo great.
Actually its no more than one trivial trigonometric mapping, Atan, per axis.
Each arm is compliant in a plane and stiff in the axis perpendicular to the plane.
The combination of constraints is that each axis is driven independently .
Have a look at some of Nicholas Seward's 3d printer designs.

I know it is easy for the computer, I am just saying it would be a pain because you would have to deal with pi because of circles and it is not going to be linear like the other ones that run similar to this. I love the design though! Its great! You just might not be able to use a build plate that big with it like that, I would recommend running some simulation to test it.

I don't find pi to be painful at all. However that is not used in in the necessary calculations to convert between linear and radians.
Its just some Inverse trigonometric functions or as simple as a Pythagorean theorem. No pain there either. The exact formula is in the Summary,

When it would be a pain I meant you could not use just the regular marlin and get away with it, you would have to make a few other modifications, and it is a pain to dig through that many lines of code to find one thing.

I see that this is currently just a concept, but I feel like with a little extra thought, a very similar mechanism COULD make a working 3-dimensionally movable contraption, which can then be fitted with an extruder. Mind if I take a crack at it?

Oh please do have a crack.

Still would make a great 3d printed art piece. have u fully printed one out ?

No sorry just these concept illustrations.

I have no way to open a .skp file. Do you have this thing in a .stl that can be used to print with?

Files are provided as posted. The design obviously never been targeted for, or is in any way suitable for print.
