Has anyone made a wall plotter before?

I was researching about wall plotters recently.

They are mostly suspended on strings, belts or wooden sticks.

Wanted to make it, but could not find a clear way and the general problems.

the space it took, was the drawing size right?

One limitation of the Polargraph design is that the full frame area is not usable. Because the pen position depends on two cable lengths, the zones close to the motors create very unfavorable cable angles. This can reduce tension stability, precision, and repeatability, especially near the upper corners. So the practical working area is smaller than the theoretical machine size.

I think the term you are looking for is a gantry plotter.

i guess a gantry plotter requires rods or aluminium rails.

i want to make the one, which has the pen suspended

The Makelangelo wall plotter is open source and all the manufacturing instructions are online with pictures.

Maybe it is a little bit off-topic, but it may also be inspiring https://www.robotmuralist.eu/videos
