How to set up Polargraph dimensions?

How to setup the dimensions of a Polargraph?
I search the MC website but couldn’t find any guides.
I only get directed to the forum here.
But the forum has no search function. Or do I not see it?

Do I measure from the motor shafts center to center?
Do I measure from the inner or outer edge of the motors?
Do I measure from the pulleys edge?
How do I measure the height?

I cannot find any written down instructions or guides.

Okay I got it.
The machine width is the distance between the center of both motors’ shafts.
The height is from top (shaft center? Motor’s bottom edge? wooden board top?) to the floor.

The machine height should be 2x the area above the home position + the paper height.

It does not have to go to the floor. When the pen is near the top corners of the paper then the weights will be below the bottom of the machine height.
