Instructables
I got inspired for this instructable when I viewed the Easy To Build Stepper Controller

instructable .When I read the instructable I knew I could make a decent looking and functioning cnc machine for under 20 dollars with a recycled twist, Not to mention I did this in under a week.

I expect you to have basic knowledge on power tools and hand tools
and of course this instructable requires you to have a rotary tool such as a dremel.
Even if you don't have knowledge on power tools or hand tools I advise you to try this instructable because you will learn a lot about hand and power tools and you can build this for less then 20 dollars
so if you mess up it's no biggie and it would not cost to much to replace a part.

Let's Build!

Update 02/01/10

{Hi everyone just thought I would give you an update on this instructable since Ive been getting
a lot of emails and messages and such.

I'm getting really close to completing the electronics for the CNC,
as stated in a comment the steppers I found in the printer were bi-polar stepper motors which the circuit
would cost quite a bit more if you went this route. If you were lucky to find some Unipolar stepper motors
then you could build the electronics for under 3 bucks however unipolar motors have less torque. I will be selling CNC kits soon and they will be of better build quality as well as a cheap price tag because I know how it is to be on a budget and not have the tools I need to create simple things and even complex things and this world needs more DIY builders.

The CNC kits will be available roughly 1 to 2 weeks after the electronics Instructable has been released
their will actually be a video showing this CNC working when the electronics Instructable is completed}

Hi Guys

This article is very good about CNC machine...

But i can suggest you also the best one

Please visit the following page to know more about the CNC MAchines

good

Cool. I might try this one.

can not

OK I have taken my share of scanners and printers apart, and I know that the stepper motor pictured in step 5 did not come from a printer or a scanner. Where did you get it?

I got it from an old epson printer sorry to disappoint you but it was from a printer
WOW thats a huge motor to come out of a printer! I need to find one of those...
Techbuilder (author)  Electronics Man3 years ago
1 1/2" x 1 1/2"is big to you?
Well apparently the images are misleading. Even if they are small, they are definately bigger than the ones I pulled out of my printers.
Techbuilder (author)  Electronics Man3 years ago
Never assume by a picture unless you have a reference point
like a ruler or a quarter so fourth.
You could also check the dimensions in step 3

umm

Alright...but are those steppers strong enough to work properly? Could you provide the brand and the ratings for them please???
Techbuilder (author)  Electronics Man3 years ago
They were minimal at best probably enough to cut through some foam and light plastic. you can only get so much torque out of a little printer motor without sacrificing tremendous speed.

I no longer have the cnc machine anymore I sold it
so I can't really provide those specs

i have 3 cd drive lens assemblies (EG: the lens shell holder, the rods, the stepper motor and the base)

could i use those to make this?

umm

you just have to check if the stepper motors are uni polar or bipolar. both will work, but they require different circuit boards. other than that I'd be worried if they are strong enough, but hey, worst you can do is try and they break

Good idea trying with this material. I think it would work best for small machines as it is flexible.
With this in mind, the drill stand frame is poor design. First its poles are way too high. The link between the drill stand and the frame of the machine should be as short, strong and direct as possible.
The other axis seem to be less fragile but could be improved.
Gluing : Not good for precision and stops you from dissassembling if you need to transport or repair the machine.
Lastly, nothing is said on how things are aligned perpendicular and parallel.

$20 for anyone who has hundreds of dollars worth of scrap perspex lying around...

I don't know where you are buying your acrylic from but I have loads, about 6 kilos in weight and its cost me little over £10!......... ebay, just look for off cuts

haha! I thought the same. One man's trash is another man's $300 project. Still a nice simple build.

is this a dead project. I see no link to the electronic portion, and the author said he was going to post those 4 years ago.

What gives???

Where can I go to find scrap materials? Is this a junk yard or a specialty store kind of thing?

where do you find a pipe mount?
You can find a pack of them for a few bucks at a gas station.

Great Instuctable. It says that the acrylic was laser-cut. What did you use to do that?
I would really love to build this but I am waiting on your electronics instructable for this.
i'm starting to build this its realy nice and it will good to have your electronics instructable for connection this and a free programm to control it.
move it on

or use a cnc to make one XD

what software do you use
LinuxCNC is a good open source software that runs on linux
lev22 squiggy22 years ago
would that software run that step motor ? or would you need something different ?
