Ok, so it seems I led a lot of viewers to believe this is a good design. Seriously, you do not want to build a CNC using this design. It is a really terrible design actually. It is better than the other two I've used, but still not really "good enough". It has way too much flex in pretty much every direction. Sorry for misleading you.
