    You could try a rotary base design. One motor rotates the base with the paper and the other swings the pen arm in an arc from the outside to the centre. A bit like a hard disk drive or a phonograph tone arm.

    As each motor is fixed to the same base plate you might get a more rigid design. 

    I've seen 'coaster plotters' done this way but they tend to use a linear lead screw arrangement to move the pen.

    If you could turn it into a gear works like this one, with drawing functionality incorporated, that would be spectacular (starts at 2:30: )

    Reminds me a bit of the kinetic sculptures by David Roy

    I think that the inspiration comes from the Tourbillon mechanism
