Using the app with other plotters/svg export

I really enjoy using the Line-us app to draw. Does anyone know how I could use this app to work with my other plotters? I’ve used Inkscape on pc to plot to the line-us machine, I believe it works over websockets? Is there any way to scrape an SVG from the ipad app for use with an axidraw/hpgl plotter?

I just looked at ws://line-us.local on my Mac and got a promising string of numbers. I don’t seem to be able to get that screen back now– I just get “Welcome to Line-us” screen. Is there a way to scrape the digital drawing?
