  It can go further than that, i just limited it to a smaller size for my first real test. I told the software that I was drawing on an A1 sized paper. Drawing this across the full board would have taken forever.

  There are a couple of no-go zones close to the corners. Longer belts would allow it to go lower, but then the counterweights would hit the floor when going up high and limit the drawing area there instead.

    Would a block and tackle solve that problem? Could 3d print them likely.

      Hmmm, only if a second pulley was higher than the motor, I imagine.

        You can use multiple pulleys and shackles to take the distance of the rope up.

        It’s how they do it inside of machines as far as I’ve seen.
