I wouldn't recommend building your own cnc router to try and save money. As ger21 said, you are only trading your time for money. I just finished building my own machine and I am very happy I did it, but I don't think I saved much cash.
This is why I think building to save money doesn't make sense:
- If I valued my time at even a couple dollars an hour then I 'spent' much more than if I had bought a machine.
- I spent a year researching, designing, sourcing parts and fabricating my cnc router.
- In that year I easily could have completed a couple of paid projects which would offset the extra cost of the router. (once you have a cnc router people will ask you to make stuff)
I do, however, recommend building your own cnc router for the following reasons:
- To learning new skills. I can't believe how much I learned about electronics and programming while building my machine.
- Pride! The first time you get the motors or the axis to move is a pretty awesome feeling! (priceless)
- You are not planning on getting paid to use your cnc router. If you have no desire to do work for other people and get paid, then it makes sense to spend as little cash as possible.
- You have no choice because you cannot find what you are looking for.
Good luck Ryan with whatever way you choose to go!
