This is the first post in a series documenting the design and build of a CNC Router. After completing the build of my first CNC router (Openbuilds OX), I wasn’t entirely happy with the performance of the machine. I decided to have a go at designing a custom machine which would better suit my expectations. After several weeks of design and analysis I came to the final design which you can see in the images above. The machine will primarily be used for cutting sheet stock; wood and aluminium.
All three axis of the machine will be ballscrew driven, dual drives on the gantry (Y axis) and single drives on the X and Z. The working envelope will be approximately 850mm x 600 mm x 140 mm.
- Welded steel base frame
- THK precision linear slides 2xSSR15x760 mm, 2xSSR20x1080 mm 2xSR15x300 mm
- Ballscrews: RM1605 (C7) – 290 mm, 790 mm, 1060 mm (x2)
- Nema 23 425 oz-in motors (‘CNC Router Parts’ 4-Axis Kit)
- 2.2kW water-cooled spindle
- CNC machined 6061 aluminium plate

I really like your design alllot! Is there a chance you share the plans with me?
Greetings from Belgium
Hey. Could you please send your project to me by e-mail? You got an excellent cnc machine!
Hi Alexander, the model is available for free download via the link on my “Final Assembly” post.
Hello to you
Well done for your work, I’m a good machinist, I’m not very good at it
drawing. I would like to know if you have a free version I am interested in young people who are going to drop out of school and I would like to interest them in making a cnc machine
To show them not to drop out of school
If possible for you
thank you and again bravo for your work
