Homemade CNC. Do you know about CNC?

Hello everyone!

I am thinking about make a homemade CNC. It is not intended to be professional machine but needs to be of good quality. A small CNC. The purpose is to cut wood.

I was wondering if a nema17 motor is a good choice.

Model: 17HS4401

With this motor I can cut wood?
Is it too weak?

Thank you

hi dear . I can help you for no money ! Zoltan

What stepper motors drivers are you using ?
To help you Dear, I need more technical information about your cnc project.

Hi,

I haven't bought the motors and drivers yet. I am in doubt if the nema 17 motors would have enough force to move the axis when go to cut wood.

Thank you.

Hi Dear. Check please Openbuilds page. They are probably give all advices what do you need... years ago, I was in same situation, so, Dear friend try Openbuilds and if you want womething

If you go to Openbuilds contact David the Swarfer he should be listed as a staff member. I know him well, and he has built a CNC last year some time. I am sure he has information. You will have to register for Openbuilds as usual.

Stepper motor is used for positioning and movement, for cutting you need a 755 dc motor

I can't offer any help, only encouragement. I did a similar project many years ago - 1985. My project was making a pen plotter. I obtained stepping motors from early generation CNC mmachines that were being scrapped at an electronics company I worked at. They were used to insert electronic components into PC board. Ball bearing droor slides were used for one axes. My main PC was a Commodore 64 and the controller was made from components from Radio Shack. I had to learn a little bit of Machine language with some of the coding coming from a PC magazine article. It was able to draw lines, circles and squares, however, the transistor that controlled the electromagnet that raised and lowered the pen continuously burned out. I'm sure the resources already mentioned here will help you complete your project. Best of luck and please post a video when you're finished.

Hi
It's not a place to talk about cnc milling machines. I think..
Try another chatting chanel please!

Since you posted here several times,that's an odd comment. I Would tend to disagree. This is chit chat and I've seen some diverse topics here. Like which laptop should I buy? How is your country doing with the virus etc...

Not much harm in the member's question.

But that said it might seem to be the end of the thread two messages back anyway.

Sorry Sir. I don't wanted to harm you at any way.. my mistake, I forgot to check the thread nature. .. Kind regards, Zoltan

the homemade cnc subject it's wery big...
...
1. you have to made your machine... the easiest part...
2. You need some 3d software, I use Fusion360, it's free for home and small businesses. Vectric Software Range have also cheap and affordable packages for amateurs and professionals.
3.You need one G code interpreter, like Mach 3 or anytthing else what suit you
...
Having ~37years experience using CNC machines (professional and home made) I always enjoyed to use them...
