I had a few months off this winter between jobs and I decided to design and build my own CNC router. I have wanted to build one of these machines for the last 6 years but regular work and life in general just kept getting in the way.

I started the design work just before Christmas and had everything fabricated, machined, ordered, delivered and built by the end of February. I have attached various pics showing some of the CAD design as well as pictures of the completed completed machine.
I designed the gantry to give me 49" x 49" x 7" of travel. I figured this would give me the ability to cut around 4' x 4' sheets and to also work with MDF which normally comes in a 49" width anyways.
I sourced my steppers and drives from China. The ballscrews and linear bearings came from China as well. I wasn't happy with the quality of the stepper drives so I ended up sourcing 4 new ones for Geckodrives in California.
I bought one of those 2.2kw water cooled Chinese spindle motors and inverters and I must say that I am very pleased with it. It is so quiet and cool when running.

Anyways, I hope you enjoy the pics and feel free to ask any questions. Thanks!

Nice looking machine.

BTW, who is your assistant designer in the first pic?

The little guy in the pic is my young (really young) apprentice! :) He is my son and is 6 years old. He helped me bolt together most of the base and table and that took all of a couple hours.
I have attached some more pics here of some of the CAD design work that I did on this job.

how is everything up in canada? just saw yr posts and machine. great job. like you, i have been looking and reading about cnc machines for a long time. now that i am retired and have time to research and build, yours is the best i have seen. i liked the mechmate router from mechmate.com, but not the v rail system. looks like the ball screws and rollers is the way to go. what software do u use as the control system? do you sell or list the parts u used in the build? any info would be helpful. thanks jim
