Building a budget cnc router?

Question

Do it yourself

Are there people who made their own machine?
Let me know what problems you are facing.
Recently on Habré there was a topic on creating a machine, and it contained links to self-assembly kits, including engines, a control module and a power supply unit. But I'm not sure whether the power of these engines will be enough, which shafts to use and what is easier to make a frame from for the stability of the entire structure.
Or are there ready-made inexpensive machines for home use that can cut through material (plywood, wood) with a thickness of more than 10mm?
I will also be grateful for links to articles and topics with a discussion of this issue.

Answer 1

It all depends on what you consider expensive and what is not. And what will be the workload of the machine. Now many manufacturers put CNC modules on machines. That is, a CNC milling for metal can be bought for 150-180 thousand, but this is such a city. On the one hand, the CNC seems to allow you to set quite high accuracy, on the other hand, the iron of the machine itself cannot withstand, backlash and so on.
I advise you to google, look for cheap CNC milling machines. The Chinese make a lot of these. But I repeat, it is not a fact that it will not fly with you in six months.

Answer 2

Of course, there are cheap inexpensive ones, before the rise in the exchange rate it was possible to buy for 145,000 now, alas, more expensive. True, it is suitable for only non-ferrous metals, alas, it is not intended for harder ones.

Now it’s easier to buy a ready-made CNC milling machine, here https://rdm24.ru/ , for example, you can take high-quality Japanese Roland machines, you can also order all the software for them there.
