Openbuilds 4x8 cnc
![](https://openbuilds.com/data/article_cat_images/s/0/286.jpg?t=0)
I built this cnc using 2 z axis actuators thinking it would minimize deflection and it seems to be very sturdy. I used 2 1500mm c channels for my x axis, 1 1500mm c channel for my y axis, nema 23 stepper motors, dm556 drivers, 2 24v power supplies, smc5-5-n-n controller, 9mm wide belts, and the Hitachi m12vc router. So far it's working very well with a few hiccups. Programming the controller was a learning experience but I'm very happy with it.

RiNo Route
![](https://openbuilds.com/data/article_cat_images/s/0/286.jpg?t=1389472260)
A CNC router designed to handle a 4'x8' sheet, for as close to $2000 as possible. The price barrier resulted in my choice to use timing belts rather than leadscrews or rack&pinion. Build List still being updated
