CNC machine DIY plans and build instructions

CNC Router Plans

CNC router plans are a great starting point for anyone wanting to build a CNC router. They give valuable insight on how these machines work. Many of us are very visual people and it helps to see examples of these machines laid out on paper. Some plans are thorough enough to act as a complete blueprint from start to finish while others only offer bits of information.

You may prefer to design and build your own machine. However, CNC router plans can still be a valuable resource. Plans can give you great ideas.

“JGRO’s” Design
This design is very popular among the DIY CNC router community. This set of plans is very detailed and contains dimensions on all parts. This is a mobile gantry type designed around a wood or MDF construction utilizing skate bearings for the linear motion system.

“Joe’s 2006 R-1” Design
This is another very popular design. This design is also a mobile gantry CNC router, designed around a wood or MDF structure. The linear motion system is also design around skate bearings. However, the x-axis employs dual rods and each side instead of one.



Build your CNC



A CNC machine is probably the most useful tool a hobbyist can own, but the price for a CNC machine on the market is way more than the average hobbyist is willing to spend.  The main purpose of this website (the mission) is to offer free to low cost solution to provide automated fabrication to hobbyists.






The .zip file below contains: a detailed, 65-page instruction set covering every step of our build, from parts lists to assembly and Linux setup; DXF files for all the laser-cut parts used to construct the gantry.

Computer controlled router 'Otocoup'




3Dcoup have a working area of 500 mm x 940 mm x 190 mm (20" x 37" x 7.5")
Overall dimensions are 1040 mm x 1300 mm x 800 mm.





Several CNC machines - Building instructions






3 axis CNC router MDF ( metric )

This CNC router machine is possible to make with just some hand & power tools.

The machine uses chinese linear rails and ballscrews from ebay seller linearmotionbearings2008. With the 1.8Nm stepper motors I use with geckodrive g540 it achieves 10m/min rapids and 5m/min feedrates. The working area is about 110cm x 60cm x 10cm.

Expected cost to build a machine like this from scratch is 1000-1300 euros. It also took me over 80 hours to build.

Tweakie CNC machine building instruction

Tweakie has been constructed as a router and designed for work with wood and plastic parts so to progress to metalworking I have acquired a small, benchtop, CNC milling machine which I have called Bob. All the original wiring has been replaced and a new controller and PSU fitted - the details of this work are shown on the ’Bob the Mill’ page.
