I wrote a big long post with responses to a number of quotes but then realized that it was overkill.

We really don't know what it is you want to cut with the CNC router part of this.

You could do some very nice wood carvings at a very slow speed with a hybrid machine, but forget about aluminum.

If you could give some more details and perhaps some pics of the cad files of what you want to make and what you want to cut exactly, the advice would be more relevant.

Trakyan, you are overly optomistic. Also, when you bump up to a router, things cost alot more. The speed of a filament printer is slow compared to a proper CNC router and very very slow compared to a commercial laser. IMO, filament printers are not made as spartan as they are in order to increase speed, they are made this way to reduce cost, and because beefier components aren't necessary to achieve the goals.

Unless you are talking about an XY area that is very large, I don't see an advantage in combining the two machines, and I think you would be better off to keep them separate.
