It's pretty crazy if it's just to generate some pictures for fun, especially when there are alternatives. I have an A3 flatbed Graphtec plotter with a precision of 0.01mm [1] that I got for something like NZD$40 (>20 years old, but perfect condition).
[1] Not a typo, but I don't have a way to check it. I use it in its "low accuracy" 0.025mm mode.
Are you able to elaborate on what you were expecting or hoping for?
