About a year ago I started looking into buying a table saw and decided to get a 3hp sawstop. After looking around I saw I could build a CNC machine for around the same money. I decided to go with the cnc machine to join my computer and building things hobbies.
Here is the CNC router table that I built. It has a 48×48 inch cutting area with a 3hp (2.2kw) spindle.
It is built from parts from cncrouterparts and 8020 extruded aluminum. It ran me around $3500 to get running.

2 8020 1530 rails (60”)
1 8020 3060 for gantry (60”)
