Strongly suggest reading through 4 or 5 of the different build thread than and getting an idea of what different folks have done. I am in the process of getting things ready to move so my CNc gantry is currently down and when i bring it back online it will be using a 2.2Kw spindle to allow both a large range of tooling and reasonable cutting ability in all the materials I work with and be able to add some additional ones as well.

Best of luck and Your link points out that I really need to put up the design of my gantry router and how to set it up for different sizes and build materials.
