Re: Joes CNC Model 2006 R-1
If you plan to build a 4x4 you should gret the plans for Joes 4x4 hybrid instead. MDF will sag if much longer than 3'. To build a 4x4 takes about 6'x6' of area. In my opinion building the Hybrid is the better course if you want a larger machine.
If you told me you planned to build a machine exactly as the plans show, then II would say the 2006 is a great choice. Once you start extending the table you are better off with a Hybrid.
