Hello everyone I am totally new to this world of cnc I want to build a cnc machine for under 500 bucks and need help Including all the parts

[elfrench]

Price is the least significant part of building a cnc machine. You'll likely get more help by giving more specifications like work area, subject material, accuracy. I don't think it would be very hard to make a working machine for under $50 from a couple of surplus printers.

It should be 3 axis with an cutting area of atleast 1mtr by 50cm

And capable of cutting aluminium and maybe a bit of steel?

Absolutely not for steel, and highly unlikely for aluminum. Typically, a machine that can do an adequate job in aluminum at that size would cost $3000 or more

Since you're budget is extremely low, you're going to really need to know what your doing to pull this off. Your post indicates that you don't.

There are no plans and/or bill of materials to build what you want for $500, so for someone to answer your first question might potentially take many hours of research. Normally for someone interested in building a machine with no experience, I'd recommend spending several months reading everything you can in this forum.
Do that and hopefully you'll have fewer questions in a few months.

But be aware that a $500 budget will usually require a lot scavenging for free or cheap parts, and the specific parts you end up with will dictate your design.

Gerry, I was being sarcastic. As commonly people come and ask for capabilities expensive machines struggle with.

A machine is doable for $500. But usable and satisfying, not really

I thought it was the OP that said that - my mistake.

Just as a plain reference.

A NEMA-23 3 axes motor driver kit runs for about $200 USD not to mention the structure of the machine, the transmissions and of course the electronics and PC.

For a machine the size requested a minimum of around $1500 USD should be considered and limiting the structure to using nothing more expensive than MDF. In this case I would consider a hand drill to be used for the tool.

As someone already posted, building a machine no matter the type, is most dependant on the desired function and application. Not the other way around. After fully defining the specs you can always play around so that cost can be minimized.

These comments are not to be discouraging. They are meant to let you know that you must always first know what you really want or need.

Just as an example of the things that can be done, the following link shows a project I´m bulding with one of my sons. It will be a small plotter using salvaged floppy drive motors.

Since we wrote the software and built the electronics we were able to reduce the cost to barely $15 USD. Of course this is just a toy and our tool will be a pen. Then again the purpose of the project was set first before even finding out what parts could be used to accomplish it.

As you can notice, the structure of the machine is still missing. I estimate another $30 USD to build it.

Best regards.
