The Root CNC 3 Lite is finished

As can be seen by the image above, the router is installed in my Dads garage and we’ve carried out a couple of test runs. All in all we are very happy with how it has turned out. I’ve got a few more parts to print to put the duet wifi in and tidy up the cabling. I also need to print a dust shoe to attach the vacuum to.

To generate the CNC gcode, we are using fusion 360. As I mentioned, we are using a duet wifi as the main controller and luckily for us, thats also the the controller used by Ooznest. They have very kindly provided us with a post processor for fusion 360 to allow the CNC gcode to be output fully formatted for the duet.

A copy of the config we are using for the duet can be found here.

I think I’m going to end up building a larger CNC router for myself as my next project once the CoreXY is out of the way.


  1. Hi Jay, I am building a CNC using duet 2 & 500w spindle, and was wondering if you are controlling the spindle via the duet 2 board or manually through the potentiometer on the spindle power supply unit.

    1. Just manually through the potentiometer. I did look at duet 2 control but manual has proven to be fine. The hardest part is calculating the speed the spindle is rotating
