Is it square yet???

Just one photo (see below) to get you thinking about squaring the CNC.  I can't over emphasize how important this step is!  It is the most time consuming step in the build process and guess what. You will need to do it again over the life of the machine.   I'm going to put together an in depth article depicting the method I used. This photo is probably a good indication......pun intended.  :-)
