I've tried lots of CNC gantry designs using a variety of drawer slides with not great results. I didn't want my work space to be moving so a lot of time was spent trying to design a stationary deck. This design seems to work pretty well. This is still a work in progress though. The next steps are to install the NEMA motors and then start working with the computer connections and G-Code.
Thanks for taking a look. I'm also always grateful for comments and suggestions.
