I started this project to enable me to do another project which required sheet wood to be machined, (another 3D printer which I have been wanting to do for a while). without the large cost of out sourcing the tasks to a company. So I created this CNC named Root 2 to open up a endless amount of possibilities.
Why make it open source? Since getting involved with 3D printing and the whole open source community, it has taught me many things and open doors which might not have been open without the added experience the community has given me. So I thought what a great way to put something small back into very thing what got me hooked in the magical world of CNC machine - the open source community.
If you make one or remix it, I would love to see it! post some photos and show it off! =]
Working Area = 331x305x120mm (X,Y,Z)
Goals of this machine
- Create a expandable CNC machine capable to machine aluminum
- Use minimal different 3D printed parts
- Customization (Make it Bigger)
- Use parts commonly used in DIY 3D printer
- Easily sourced parts
- Print with 3-4 perimeters
- Print with ABS but PLA will be fine though your mileage may vary

Generate the Gcode
I use PathCam, free open source software with minimal settings to enter to get up and running. Its not perfect but still does a great job! see link for more information.
What is the working area of this machine?
- 331x305x120mm (X,Y,Z)
What Firmware or Software do you run on the Arduino Mega?
- I use Marlin the 3D printer firmware. only because I know my way around it very well. I have not used GRBL yet but would like to try it. Marlin has a strong community and most questions have been asked regarding it.
Animated assembly guild:
I've updated the file structure to hopefully make it easier to find parts.
Also added the option for a NEMA 23 Motor for the Y axis!
Added a 65mm and 66.4mm Spindle Mounts as requested. Theses Are REV2 design which incorporate the option for a lead screw nut or normal M8 nut options in one design!
Removed Prototype parts (from update 7). Theses parts were to premature for released and have been removed - see Facebook conversation for any latest work.
Animated assembly video's, these are a work in progress for when I get more time. more will be added soon
Added FAQ's at the bottom of this page, It will be updated as and when I receive a question.
Added the option to use the Dewalt 611 / DeWalt D26200 or any other 69mm Diameter spindle on this machine! (Untested - Awaiting delivery)
Added the following files to use 1 inch box section* instead of the 25 mm box.
- X-Axis Box Bar Mount INCHES
- Y-Axis Bar Mount INCHES
- Y-Axis Bar Mount Idler INCHES
*Theses are untested though the slot has been increased by 0.4 mm from the original to accommodate the 1 inch box.

Rev 1.1 updated .STL files
- Theses are updated file which will reflect the Plastic Parts BOM Blow Use theses new files.
- Part Improvement on;
- Spindle upper and lower mount tweaked - Placed the logo on upper file and blanked the bottom
- Y-Axis Bar mounts Tweaked - Added option for cable management to ran through the aluminium box section. this can be useful for the min and max end-stop cabling.
- Y-Axis Motion Bearing Mount - Increased area to allow for more motion to tighten up the M8 clamps nuts. (It was difficult to do before)
- Removed the pointless prototypes of the 3M pulleys and only uploaded the sizes required
Special thanks to the people who have given me the ideas to come up with this machine. There have been many hours of YouTube videos watched over a long period of time, many hours searching google and most of all many hours printing. I cannot comment on all sources of information but here are a few which standout;
People and groups worth mentioning;
https://github.com/CarlosGS/Cyclone-PCB-Factory for getting me into this in the first place
http://reprap.org/ for giving me the printer which printed a printer. To which that printer, printed the parts for a CNC machine - to machine the new printer. Of which this printer helped print the new piece for a new machine! very fitting for the RepRep self-replicate philosophy.
http://www.thingiverse.com/Rukey/designs/ great place for ideas
http://www.thingiverse.com/thing:41594 inspired the first Mill (Root 1 which wasn’t released as it wasn’t great :P)
