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.
<p>An interesting and innovative approach. I like the box based design because it adds a level of stiffness that is sometimes not there in other designs. </p>
Thanks sleeping. I love doing this stuff. <br>WWC - Haven't really been able to measure the slop yet. The more I tighten nuts and add the lead screws for each axis the tighter the whole thing gets. I'm sure it won't compare well to an all metal machine, but for woodworking it might offer some good results.
I am enjoying the creativity.
Have you been able to use a dial indicator to check for slop in the slides? Can you feal any by hand?
