Ok, i am fairly new to all this. I have studied and downloaded alot of free plans for the homeuild cnc's. However I am trying to figure out exactly what i need.

I need a machine to cut up to 3/4" mdf (possibly ythicker with more passes, i am looking to use 2 1/2" mdf.

I make custom speaker boxes. I need the thing accurate, but reallyonly to a 1/16" in reality, as everthing get sanded and carpeted.

i was hoping to either have about 24" x 48" up tp 48" x 48" of travel.

I am not sure what plan to use to build my first machine, what size router to use, or what size motors.

basically, if someone could point me in the diretion of either free or cheap plans for a machine like this, it would be great.

Oh, i also have a large 4' x 20' cnc at work to machine the parts for my cnc. i was thinking of using baltic birch ply, is this a good choice?
