The Qidi Max 4 doesn't report that it's a Qidi Max 4 via /server/info
like the other Qidi printers apparently do. This means that filament
matching is a fool's erand because you'll never actually match anything.
this adds a fallback where we just use the configured machine type. I'm
not sure why we wouldn't just do that all the time, but I wanted to
change as little as possible.
