Didn't really work for me. I asked it for something I hacked together myself in the past, so I have an idea of what I want, and I also know that resources like this exist on the internet. So it seemed like a fair test.

Prompt:

"I want to build a V-plotter (carriage hanging from two points, connected by light chain or belts). How can I figure out the dimensions of the printable area that will have good print quality? Good quality requires that there is enough, but not too much pull on both chains."

Result:

Yes, it has some form elements to adjust values. But it's not really interactive and the "map" it talks about is not showing. Also "Keep both chains between 0.5 m g and 1.5 m g" sounds like nonsense.

You also get the usual LLM crap like "Loose belts cause skipped steps and misaligned layers" where "layers" clearly refers to 3D printers and has no meaning here.

What I expected:
