So why here?

Well, it is a variation of h-bot and it does, in fact, share the same kinematics as COREXY. We have seen that already called as Core-T by some (see Jason McMullan's design )

Mine is a vertical drawing machine based in the same principle. Using the usual suspects: printed parts, threaded rods, 8mm rods, LM8UU bearings and stepper motors and a microservo.

Interesting- do you find that the pen wobbles when it's down at the bottom of the Y axis?
How fast can you run it?
Does the whole thing fold up for compact transport?

Interesting indeed.

Now you program it to draw the Bansky little girl with the red balloon (NOT baboon), call it "Bansky UNshredder" and cash a few millions smiling smiley

It works ok if acceleration is kept low (mine is 100mm/s^2 now) and speed (using 2000 mm/min max at the moment). The current design is not foldable but Y axis is not bolted or glued, so you just remove the belt and pull it easily out for easy transport.
This is is not a precision plotter but still reasonably accurate for writing text, not good enough for drawing a PCB.
