Ryan is totally right, but don’t worry too much, because once you have one, you will quickly want more! Maybe start with a 3D printer though, either the MP3DP or a smaller MPCNC. Then you can make another machine, and another and another…
I am not an accomplished woodworker, but I’ve watched a lot on TV. I have a 3’x4’ MPCNC (with a bit more than a 2’x3’ work area) and I would suggest that you may not need, or be happy with a larger one. You can do some operations in multiple steps, and there are a lot of projects that don’t need to have a CNC for the larger stuff. For example, if you just want to do some CNC cutting on the side of a cabinet, then you can cut the cabinet on your table saw, and then reference the outer edge somewhere in the work area, and make your CNC cuts in that area. But the workpiece will have to fit between the legs of the machine still. I’ve used it to engrave onto long boards by writing half the words, then moving the workpiece and writing the other half, etc. I’ve also thought about just using it to make templates, and then use the router with a flush trim bit. There are a lot of ways to make this work larger than it is.
If you are hoping to just cut cabinets over and over again, or big furniture from opendesk, then let’s hope Ryan releases the low rider soon. While you wait, you can get your feet wet in 3D printing.
